FMD090EV EXTENDED VOLUME METER PROVER
FMD’s latest addition to its proving family is the state-of-the-art Extended Volume Prover Line. The FMD-090EV small volume meter prover is designed specifically for proving manufactured pulse meters such as Coriolis, ultrasonic and helical turbine meters. With a 50% greater volume capacity, at 120 gallons compared to 80 gallons for the standard FMD-090, the FMD-090EV allows for larger sample sizes and extended flight times making it the ideal choice for proving manufactured pulse meters.
