Singapore Branch K. Page istockphoto. Electricity meter HAN Gas meter While this is no easy task for any country, the competition-based structure of the UK utility sector, and the complexities of existing prepayment billing systems, have necessitated a unique architecture to be deployed.
A central Data Communications Company DCC will be procured and licensed and installed by with competing energy suppliers being responsible for deploying meters which provide interoperable data against defined protocols, supporting a sustainable platform for competition in the future. Six technologies had been short-listed and evaluated against different weighted criteria. ZigBee Smart Energy scored highest in the evaluation and is a preferred standard in the UK for smart meters and home area networks, allowing over-the-air upgrades of firmware as well as secure data communication.
In this respect, ZigBee is able to provide customers with the latest improvements and new functionalities. Elster gas and electricity solutions are able to support the latest mechanisms for data protection and system security. Elster is one of the few organizations that can provide an end-to-end solution from meters, through home area networks and wide area communications, into head ends and meter data management services in the back office.
An essential part of any security solution is simplicity and integrity. Initial smart trials, with proprietary technology, have been ongoing for some time. Our solution to the UK requirement is scaleable to cover either metering as a component to a defined architecture, or alternatively, a managed end-to-end capability including head end and MDMS. However, the last 2 years have shown a dramatic reduction in the volume of demand for these meters as both utilities and metering asset owners, become increasingly aware of the risk that these meters will be removed and replaced as part of the smart deployment model, effectively stranding their initial investment.
In terms of capital investment, this is a sound decision, but this perspective puts increased pressure on the roll-out by reducing the number of active meter installers required, at a time when these resources actually need to be expanded to cope with smart technology Elster may have the answer. The modular design used by Elster within our smart portfolio allows our fully compliant smart meters to be installed without a communications module, thereby operating in traditional credit meter mode.
In addition to its acknowledged high product quality, this process has been helped by its extremely compact design and the fact that it also offers great flexibility in terms of safety features and connection variants. One of the deciding factors in this decision was the extremely low design length of the M2R which enables it to be installed in the same installation space as its predecessor model, the Furthermore, good accessibility of the downstream pressure setting, the SSV reset and the pressure test point were also important for the selection of the connection configuration.
This means that the M2R can be used not only for new installations, but also as a replacement in existing meter boxes. This, together with its robust design, made it an easy choice for HMN after a series of field tests.
For internal training, HMN has produced a short instruction video showing the installers how to install the regulator and check its settings. The two-stage regulator guarantees the regulation of the downstream pressure which is independent of the upstream pressure, covering a wide upstream pressure range of 0. The compact design of the M2R combined with its variation and sturdiness means that it can be used to modernise domestic meter boxes.
Today, we would like to put forward another solution, but first here are some passages from the past article to give you a brief overview of the facts: In many systems, gas meters are installed whose indexes do not generate a sufficient number of pulses at least pulses per measuring period at 0. The problem of inadequate pulse generation is due to the technical equipment of gas meters of sizes G and G For an 8-digit roller index, there must thus be 7 figures before the decimal point and there remains one figure after the decimal point which generates one pulse per m 3.
Consequently, only 48 pulses per hour are issued at 0. The exception to this are gas meters which have a 9-digit roller index with two figures after the decimal point and a pulse value of 10 pulses per cubic metre. By agreement with the regional calibration authorities and the German National Metrological Institute PTB , the following specifications apply for existing and new systems in commercial transactions between supplier and end user with the invoicing of measured capacities: 1.
In the case of existing systems, measured capacities may only be invoiced if the value invoiced is based on at least 50 pulses. This is to be ensured by the supplier. New systems must be designed by meter operators in such a way that the gas meter issues at least pulses at 0. In the case of new systems, measured capacities may only be invoiced if the value invoiced is based on at least pulses.
As a technical solution, the installation of meters whose integrated or connected pulse generator has a higher resolution e. It has been available in the following versions since 1 August 1. Index S1V with pulse disc E10 This pulse disc supplies a pulse which is 10 times higher than that of index Z6, i. Index S1V will also be available as of mid in conjunction with mechanical temperature conversion TC.
Look forward to having one less problem! Lead times for gas meters today are essentially dependent on the facilities available in the sector of high-pressure test rig technology. As long ago as , the first high-pressure mobile calibration test rig produced by Elster-Instromet came to China. In , Elster-Instromet delivered another highpressure mobile calibration test rig to PetroChina. In May this year, a new generation of mobile calibration test rigs successfully passed the final test at pigsar.
Elster-Instromet made full use of its experience of the last two generations of mobile calibration test rigs and also of its innovative potential. Sinopec is China s largest state-owned enterprise, and its revenue in was about USD billion and it ranked 7 th in the Fortune Global The mobile calibration facility is installed in a truck. This unit is equipped with a calibration data acquisition system and comprises three turbine master meter lines, one meter under test and an ultrasonic reference meter.
Each of the meters is equipped with an inlet and outlet spool and a flow straightener. The parameters of the meters are as follows: Sinopec, pigsar and Elster-Instromet project team The parameters of the test rig are as follows: Measurement uncertainty: U 0. Furthermore, the RGC software is installed on the supervisory computer for configuration and maintenance purposes.
The software on the supervisory computer of the mobile calibration test rig is the Instromet Supervisory Suite ISSplus. It has been developed by Elster- Instromet based on Microsoft. ISSplus is a synergy of the latest software technologies and the extensive experience we have gathered in gas metering applications over the last 12 years with the current ISS.
It provides the operator console with controlling, alarming, trending and reporting functionalities. Calibration certificates and reports are stored on disk in PDF format and can be printed via a normal printer.
The supervisory computer SVC consists of an industrial PC with serial and Ethernet ports for communication to all equipment in the calibration system. Furthermore, four solenoid valves and a pressure transmitter are provided to check for leakage. A PLC, which is integrated into the supervisory system, is used as an IO extension for the supervisory system and is dedicated Q.
Putting the correct master meter in series with the meter under test MUT is done by the system via motorized valves. The flow through the master meter, reference meter and MUT is controlled by the three flow control valves downstream of the master meters. The reference meter, master meters and MUT are connected to a calibration data acquisition system which performs pulse measurements. The master meters are connected by using a dual pulse output. The reference meter and MUT are connected using a single pulse output.
The calibration data acquisition module performs the pulse measurements by determining the flow through the master meters and the MUT using so-called dual chronometry processing, thus achieving the highest possible accuracy in pulse measurement. The ultrasonic reference meter has an RS serial connection to the supervisory computer for transmitting diagnostic information. The master meter and reference meter were calibrated at pigsar before being installed in the truck.
After installation, they were calibrated at 20 bar and 45 bar to be as close as possible to the actual operating pressure. The calibration differences of the master meter and reference meter before and after installation in the truck are very small, and these data show that flow meter errors at 20 bar and 45 bar also differ only slightly, which means that the performance of the meters is excellent.
We would like to take this opportunity to express our thanks to pigsar, and to all those who worked in the project team, for their excellent work and strong support. Nowadays, there are many different types of screw heads, all requiring separate screwdrivers.

Oil / Fuel / Chemical Meters
Electricity meter with communications system If, for example, commercial gas meters are connected to a data logger, but are to be integrated into a smart M-BUS system at a later date, a diaphragm gas meter with the new Absolute ENCODER can be installed without having to dismantle or replace the meter on site. M-Bus Meter Bus is a fieldbus for use in consumption data acquisition. Data is transferred in serial form over a two-wire cable protected against reverse polarity from the connected slaves measuring instruments to a master.
The Absolute ENCODER is an index for diaphragm gas meters, which records and displays gas consumption in exactly the same way as a mechanical roller index. The position of the digit rollers is scanned opto-electronically and the absolute meter reading is transmitted via an interface and standardized communications protocols. The operating energy for the diaphragm meter is derived from the gas pressure.
The M-BUS master is integrated in an electricity meter or in a data concentrator e. For this application, no batteries are required. The same goes for new devices.
A selection of communications modules can be retrofitted or replaced at any time. You can find the diverse possibilities of combination with other components for data transfer in the illustrated diagram.
Due to its robust mechanical construction, the same calibration terms apply as for standard diaphragm gas meters. The Elster Jeavons S over pressure slam shut valve is now available with a standard micro switch to give remote indication of the unit having tripped.
A similar switch had been offered previously, but due to the high specification required, the cost was often off-putting. Initial entrance into the peritoneal cavity was obtained via the Hasson technique. The abdominal cavity was insufflated with CO2 to achieve an intra-abdominal pressure of 10 — 12 mmHg allowing for adequate visualization of the intra-abdominal organs.
This pressure was constantly monitored and adjusted as needed throughout the procedure. Two additional 5mm trocars were placed under direct visualization, one in the left hypogastric region and one in the right hypogastric region. The cecum was identified and an approximate four-centimeter perforation was made on the anti-mesenteric side, at least one centimeter away from the terminal ileum, via a laparoscopic shear device. Fecal material was allowed to flow out from the perforated cecum to induce intra-abdominal sepsis.
Attention was then directed to the liver.
The left lobe of the liver was identified and measured with a sterile plastic ruler in the cranio-caudal aspect using atraumatic graspers to retract the lobe laterally.
Once the liver injury was completed the CO2 was immediately evacuated from the peritoneal cavity, all laparoscopic ports were removed, and the port sites were temporarily closed with nylon sutures to achieve abdominal wall continuity.
The area was excised down to the level of the muscle fascia removing the skin and subcutaneous tissue. Injury severity score as a result of these injuries was calculated as 21 meeting criteria for severe trauma.
Hemodynamic parameters were monitored during this time.
Anesthetic gas was adjusted during the injury phase to minimize the anesthetic effects on blood pressure while ensuring adequate sedation.
The incision was carried through the peritoneum to gain access into the peritoneal cavity.
The liver was exposed and liver packing was performed. Once hemostasis was achieved the liver was repaired by over-sewing the cut edge with chromic sutures and cauterizing the raw, exposed parenchyma.
Intra-peritoneal blood was evacuated via pre-weighed laparotomy pads for measurement and subsequently weighed in order to formally quantify blood loss. After control and repair of the liver injury, attention was then directed at repairing the cecal perforation.
The inflamed edges of the cecal injury were resected with metzenbaum scissors, and a two-layered intestinal repair was performed. Full thickness apposition with vicryl sutures was performed followed by imbricated seromuscular sutures of silk.
All intra-abdominal fecal contamination was removed and the peritoneum irrigated with warm normal saline until the effluent was clear. The abdomen was then closed in two layers with running sutures and the previously placed laparoscopic trocar sites were re-approximated with absorbable suture. To mimic clinical practice during the hospital phase, the intra-operative resuscitation was targeted to physiologic parameters during the hospital phase.These range from small measuring systems to complex biogas injection rigs, which are becoming increasingly important in the context of climate protection policy.
Information on the latest functions and features offered by Elster products, and on new technologies was imparted and discussed intensively at the training centre in Mainz-Kastel. Lung mRNA gene transcript analysis Total RNA was extracted from freshly isolated lung tissue using standard trizol-chloroform-ethanol extraction procedures. Regarding the triedand-tested turbine gas meter technology, its long recalibration interval is doubtlessly of great use, i.
To be able to manipulate the common types of screws, you need a well-stocked toolbox. Her inability to make her choices consistent over time is what compels her to seek treatment.
Since , the company with its six employees has increasingly turned towards the natural gas market. This is to be ensured by the supplier. By using an external impulse downstream of the regulating equipment, the S will rapi The trip off pressures then vary from as low as 18mbar up to 1.
Results are expressed as the mean difference in relative fold gene expression.
