Contrec 515 Mass Flow Computer with Master Proving (MP02)

The Contrec 515 MP02 is a reliable solution for measuring the mass flow of various products. This advanced instrument utilizes the frequency output from a mass flowmeter and features an additional “master meter” input along with a Meter Factor for in-line proving, ensuring precise flow measurement.

The master meter input enables an “on-the-fly” proving run to be conducted against the line meter without disrupting the flow. A recommended Meter Factor is calculated and can be easily entered, guaranteeing accurate measurements for current flow conditions or compensating for any minor degradation in the line meter’s performance.

This flow computer effectively maintains the line flow rate and totals independently from the proving totals. Proving runs can be conveniently controlled through RTU Modbus communications or via the logic inputs located on the rear panel, making it an essential tool for industries requiring precise flow measurement and control.
