Plum - MacBAT 5 - Electronic Volume Converter

Gas Volume and Energy Electronic Conversion Device with Integrated 2G/3G/4G LTE Modem

MacBAT 5 is a gas volume corrector that enables PTZ, PT or T conversion. The device is designed to measure volume, energy and flow of gas. Primarilybattery powered with the possibility to connect external power supply. 

Plum - EVC - MacBAT5The device converts the volume of gas counted by the gas meter (turbine, rotary, ultrasonic) into the base conditions.

Gas compressibility factor is calculated with the use of algorithms SGERG-88, AGA8-92DC, AGA8-G1, AGA8-G2, AGA NX-19 mod (all algorithms with possibility of use of full gas composition) or constant value of relative compression factor.

MacBAT 5 is an intrinsically safe device ready to be installed in explosive hazardous zone 0.
