Thermal Instruments for Rugged Environments

Fluid Components International’sFLT93 switch, ST98 flowmeter, and GF90 and GF92 flowmeters havereceived IEC/IECEx approvals for their safe use from the InternationalElectrotechnical Commission (IEC). FCI’s thermal mass flow switches andflowmeters provide precision flow measurement, high reliability inrugged operating conditions, low maintenance, long-life and lowcost-of-ownership.  A microprocessor-based designs feature ano-moving parts thermal mass flow sensor, which makes the instruments agood fit for a broad range of industries, including:  chemical,energy and power, food/beverage, oil/gas, pharmaceutical, water/wastewater treatment, etc. The Flow/Level/Temperature (FLT) flowswitch monitors the flow, level and temperature of liquids, gases,slurries, syrups, lubricants, coolants, and more.  It is a goodfit for tank level monitoring and pump low-flow protectionapplications. The rugged ST98 flowmeter operates over a flow range from0.21 to 172 NMPS in air with a standard flow accuracy of +/- 1 percentof reading, +/- 0.5 percent of full scale. It is ideal for a wide rangeair/gas flow measurement applications, including natural gas or methanemonitoring, compressed-air metering, industrial HVAC systems, nitrogenblanketing and combustion air. The GF90 is a heavy-duty industrialflowmeter designed for applications that include:  flare gas,combustion air to boilers, scrubber balancing, exhaust stacks, andmore. The GF92 is a heavy-duty flowmeter that offers excellent low-flowmeasurement characteristics and is ideal for compressor fuelmonitoring, nitrogen purge monitoring, digester gas monitoring andhydrogen make-up gas.
