Gas flow computer Z-FLOWCOMPUTER-B

for liquidsfor waterfor steam

Product Description: Z-FLOWCOMPUTER-B is a flow computer for water, steam, and gas applications. The unit is equipped with 4 PNP/NPN digital inputs, 2 voltage/current analog inputs, 1 universal analog input, 2 relay digital outputs, and 1 analog voltage/current output. The versatility of this controller, guaranteed by different standards of input signals, allows its use in applications such as corrected flow or energy efficiency calculation for white certificates issue. Water and steam applications compressibility factor is calculated conforming to international standard IAPWS IF-97, while flow rate totalization and compensation for both NATURAL and REAL GAS are calculated according to SGERG88 ISO 12213-3, AGA8 GROSS, AGA8 92-DC ISO 12213-2, RK and RKS algorithms calculation standards.
