3.Description of metering principle
The MPFM can carry out the three-phase automatic metering of oil, gas and water production from tested well. It uses duplex-body tanks to measure liquid flow, a vortex meter for gas flow. And a water cut device is used to measure at interval time and calibrate water content of crude oil.
PLC automatic metering control cabinet controls automatically the process of metering and water cut measurement, collects data of each instrument and calculate and display the metering results.
