PRODUCT DESCRIPTION
Elster EK220 Gas Volume Converter
The EK220 is a battery-operated volume converter. The device records the low frequency operating volume pulses of a gas meter, measures the operating pressure and temperature of the gas and calculates the compressibility K as well as the conversion factor C. The standard volumes, standard flow rates and operating flow rates can be calculated using this initial data.
In addition to volume conversion and data logging, the EK220 may be used for the flexible data recording of different measurements and, in conjunction with either a modem or RTU, for system monitoring.
- T, PT, PTZ volume conversion
- Conforms to European standard EN 12405
- MID approval
- Compressibility calculated in accordance with different methods
- Flexible, integrated data logging function
