Pressure, temperature and fluid rate control at ESP (Electrical Submersible Pump) discharge.
IRZ TMS-R system includes additional downhole remote unit, measuring flow rate, pressure and temperature of production fluid, passing through the unit. In the flow transducer there is a vortex method of measuring, which differs from “spinner” type in wide range of measured fluid rates and absence of moving elements.
Various types of configuration in production systems and for the downhole pumping — both upward and downward schemes.
To implement a configuration you need to lay only one cable in a tube close to Electrical Submersible Pump.
Configurations: a) IRZ TMS-R1 for production system; b) IRZ TMS-R1 for downhole pumping; c) IRZ TMS-R2 for downhole pumping with a downhole sensor with a thru shaft
