• modelEK205

The EK205 is a battery-operated volume conversion device that can be easily mounted onto gas meters from Elster or other manufacturers. Powered by a lithium battery for a minimum five-year service life, the device calculates gas volume at base conditions on the basis of consumption data supplied by flow-proportional pulses from the connected meter and the measurements of gas temperature and pressure. The data logging function, serial interface and different data communication protocols allow integration in head-end and Supervisory Control and Data Acquisition (SCADA) systems.

The smart multi-functional themisalpha index for diaphragm gas meters provides features, which go well beyond simple remote reading. The combination of existing options (time- and load-dependent tariffs, valve control, load profiles, communications interval control, data logging, etc.) enables the index to be adjusted to suit the needs of individual customers. A wide range of communications solutions for the themis-alpha index guarantee the authenticity and integrity of the data transferred between the communications partners and also allow granting authorization to users. A secure, remotely controlled software update and the modular principle guarantee that the technology is future-proof and also that it can be adjusted to meet new challenges retrospectively at low cost if necessary.

• Model NumberRABO G16 - G250

RABO combines tried-and-tested product features of previous rotary gas meters from Elster-Instromet and is a convincing product because it offers a large range of future-oriented features. The device is suitable for measuring gases of the first, second and third families pursuant to EN 437:2009 and for measuring a range of technical gases.

• modelTRZ2

The TRZ2 is serially equipped with permanent lubrication bearings as well with the mechanical S1 Index. From ANSI class 300 upwards all meters are equipped with manual oil pump as standard.

• modelCHEKKER

The CHEKKER is a patented meter which generates a two-digit check number in its index. The number is generated mechanically and the system requires no maintenance. This check number is encoded. When the meter is read out the check number is also registered and, with the help of a software module, the number enables the user check whether the meter reading is right or wrong. To do this, the check number is automatically decoded before the data is processed by the billing system.

• Series3000 SERIES

The unique design of the 3000 industrial regulator is used for distribution, commercial and industrial applications. It is best suited for furnaces, batch ovens and boilers.
