Elster EK 205
The Elster EK205 is a battery-powered volume converter that can be easily mounted on gas meters from Elster or other manufacturers. The device is powered by a lithium battery with a minimum service life of five years (optional external power supply of 6-9 VDC, max. 50 mA is possible). The EK calculates gas volume under standard conditions based on consumption data provided by flow proportional pulses from the connected meter, as well as measurements of gas temperature and pressure. The EK205, in the version without a pressure sensor, can also be used as a temperature converter.
