Contrec 515 series with MP02 application measures the mass flow of a product. The instrument uses the frequency output from a mass flowmeter and has an additional “master meter” input and Meter Factor for in-line proving.
The master meter input allows an “on the fly” proving run to be carried out against the line meter without interrupting the flow. A recommended Meter Factor is calculated and can be entered to ensure accurate measurement for current flow conditions or to cater for a slight deterioration in the line meter.
The flow computer maintains the Line flowrate and totals independently of the proving totals. Proving runs can be controlled via the RTU Modbus communications or via rear panel logic inputs.
