The newest solution manufactured by PLUM is aimed at the highest international requirements. MacBAT 5 (Volumetric Flow Meter)is ATEX and IEC Ex certified. Pulse inputs variety makes MacBAT 5 (Gas Volume Corrector)compatible with most gas meters available on the market: double LF inputs, HF, Wiegand, Encoder SCR, and NAMUR. Possibility of backward gas flow detection using two LF inputs. Integrated or external pressure transducers are changeable during normal operation. Configuration using NFC interface. Casual, available on the market batteries designed to work and being changed in Ex Zone 0. Gas compressibility factor is calculated with the use of algorithms SGERG-88, AGA8-92DC, AGA8-G1, AGA8-G2, AGA NX-19 mod or a constant value of relative compression factor. Cooperation with EM-1 and EM-2 extension modules expands EVC functionality for additional current and binary outputs and NAMUR signaling inputs.
