Gas volume correctors ELCORplus

The new ELCORplus gas volume corrector offers a powerful solution for commercial gas measurement purposes.

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

Information about the gas flow volume is sensed through the pulse outputs of the gas meter or through the encoder data output. Gas temperature and gas pressure are measured by integrated digital transducers. The degree of gas compressibility is calculated by the device according to conventional methods or a fixed value can be used.

The device's design with respect for future extensibility enables the customer an easy supplement of the device's functions. In the case of the ELCORplus model, the device can be equipped with up to two RS232/RS485 serial interfaces, an internal modem (available variants for 2G/3G/4G/NB networks), an external modem, up to 12 digital inputs, analog inputs and outputs 4 - 20 mA, and the possibility to install an interface for connecting the NAMUR or SCR+ encoder.
Up to 6 digital pressure and temperature transducers can be connected to the device.

Thanks to its wide hardware options and flexible software features including basic telemetry, the ELCORplus is one of the most equipped and powerful volume correctors on the market.

The extended measuring ranges of the pressure transducer makes it easier for the customer to order a proper corrector.

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

ELCORplus wireless connectivity enables connection of two modems simultaneously (internal+external or 2x external). Internal modems are available for 2G, 3G, 4G Cat1, 4G Cat M1 and NB (NarrowBand) networks and can be used in ZONE 0 explosive environment.

All device communication interfaces are mutually independent.

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

The device´s housing was designed to operate in harsh outdoor environments with certified IP66 protection.
