Model AS-FT Flow Sensor
Brand: Fluid Components International LLC (FCI)FCI’s Thermal Dispersion Technology (TDT) directly measures mass flow of air, gases, water or liquids, which saves cost, installation space, and weight over alternatives that require the addition of pressure and temperature sensors, and a flow computer to infer mass flow.
FCI flow sensors are also inherently dual-function, and temperature measurement of the fluid is readily available from the same sensor element.
The flow meter system typically consists of a flow element that is inserted into the customer’s process and a control unit that can be mounted integrally or remotely. The wetted portion of the probe is hermetically sealed, made of stainless steel parts joined by gas Tungsten arc weld or nickel braze.
The element construction provides excellent corrosion resistance that can withstand up to psig: 2,000 (kPa: 13,790, bar: 138) or more in line pressures. The insertion length is specified by the customer to position the thermowells in the center of the flow stream.
