Dynamic Flow Computers Micro MV Flow Computer with Rosemount 205 Multivariable Module 0-3626 PSIG

This unit is a Micro MV flow computer. Its nameplate identifies Dynamic Fluid Measurement Inc. of Stafford, Texas, and the Micro MV product line is published by Dynamic Flow Computers, also of Stafford. The Micro MV is described by the maker as a 32-bit, dual meter run custody transfer flow computer for liquid, industrial gas and natural gas measurement.

The unit carries a Rosemount 205 multivariable sensor module, which measures differential pressure, static pressure and process temperature in a single device. The flow computer uses those readings to calculate corrected flow for the meter run. The module on this unit is labeled for 0 to 3626 PSIG static pressure and -250 to 250 inches of water differential pressure.

Instruments of this type are used at natural gas wellsites, pipeline meter stations, gas processing plants and liquid custody transfer points, where measurement technicians and operators need an explosion proof, field mounted computer that runs on low voltage DC power and reports over Modbus.

Available from King Surplus inventory in Del Rio, Texas.
