Gas volume corrector ELCOR

The new ELCOR gas volume corrector presents a powerful solution for commercial gas measurement purposes.

The ELCOR is the device designed to convert the volume of gas measured under operating conditions to volume under base conditions.

The gas flow rate information is sensed by the gas meter pulse outputs or encoder data output. Gas temperature and gas pressure are measured by integrated transmitters. The degree of gas compressibility is calculated by the device according to conventional methods or a fixed value can be applied.

The device's design with respect for future extensibility enables the customer an easy extension of the functions, which in the case of ELCOR model means the possibility of modem installation or replacing an existing modem with a newer one in the future.

The basic features of the ELCOR are the integrated RS232 / RS485 serial interface, allowing connection to the data collecting / SCADA system, 3 digital inputs (low frequency or binary), 2 digital outputs and the option to connect the NAMUR or SCR + encoder interface. A maximum of 1 pressure transducer and 1 temperature transducer can be connected.

The extended measuring ranges of the pressure transducers make it easier for the customer to order a corrector.

The ELCOR is also available in a version capable of measuring and operating in temperatures from -40 °C.

All communication interfaces are mutually independent.

The ELCOR includes a data logger as an integral part of the device with a large 16MB memory, allowing to store measured data at hourly intervals for more than 10 years.

The housing was designed to operate in harsh outdoor environments with certified IP66 protection class.

The ELCOR corrector has been designed for measuring spots where only battery power is required, so an external power supply option is not available. If it is necessary to use a corrector with external power supply (e.g. very frequent communication with the device), it is recommended to install a more advanced ELCORplus model.
