ELCOR
Electronic Gas Volume Corrector (EVC)
ECLOR is an Electronic Volume Corrector (EVC) used with various types of Natural Gas and LPG Meter which includes RPD, Turbine and Diaphragm meter for the PTz (Pressure, Temperature, and compressibility) correction at Standard condition. ELCOR is designed with respect to the future extensibility which enables the customer an easy extension of the EVC functions, means the possibility of modem installation or replacing an existing modem with a newer one in the future.
About Product
ECLOR is an Electronic Volume Corrector (EVC) used with various types of Natural Gas and LPG Meter which includes RPD, Turbine and Diaphragm meter for the PTz (Pressure, Temperature, and compressibility) correction at Standard condition.
The basic ELCOR is integrated with RS485(RS232 optional) serial interface, allowing connection to the data collecting SCADA system, with 3 Digital Inputs (DI) - Low Frequency (LF) or binary), 2 Digital Outputs (DO), and the option to connect with NAMUR or SCR + encoder interface for High Frequency (HF) pluses.
The extended measuring ranges of the Pressure Transducers make it easier for the Customer to select a suitable EVC for their application. It also have large 16MB memory which allows to store measured data at hourly intervals for more than 10 years. The housing of EVC is designed to operate in harsh outdoor environments with a certified IP66 protection class for better safety.
