The MacBAT 5 corrector offers PTZ, PT, or T type corrections. The device is powered by an internal battery with the option of external power connection. MacBAT 5 converts gas volume measured by a rotary, turbine, or ultrasonic gas meter to base conditions. The gas compressibility factor is calculated using algorithms: SGERG-88, SGERG-mod-H2, AGA92-DC, AGA8-G1, AGA8-G2, AGA NX-19-mod, or a constant value of the compressibility factor K1.
MacBAT 5 is an intrinsically safe device that can be installed in Zone 0 explosive hazard areas.
