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 make 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 the 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 an integral data logger with a large 16MB memory, allowing it 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.
