New Mass Flow Meters Combine Accuracy, Long-Life & Economy In Green Energy & Pollution Monitoring

Process and plant engineers interested in green energy and pollution reduction applications will want to see FCI’s ST51 and ST98 Flow Meters which deliver accurate flow measurement at an economical cost in green electric power co-generation and pollution monitoring/control applications.

FCI’s (USA) ST Series Flow Meters feature rugged, no-moving parts designs suitable for hazardous plant environments requiring biogas capture and recovery systems for power generation and pollution control. The ST51 and ST98 are designed with a precision thermal mass flow sensing element, built-in temperature compensation and advanced transmitter electronics. The ST Series provides air and gas flow measurement with exceptional performance, low maintenance, long life and a low life cycle cost.

The innovative ST51 Flow Meter is designed specifically to measure biogas, digester gas, and all methane composition gases including natural gas. The ST51 features a thermal mass, insertion-style flow element with flow accuracy to ±1% of reading over a broad flow range from 0.3 to 400 SFPS (0.08 to 122 MPS), and repeatability of ±0.5 percent of reading. Approvals for use in hazardous environments include FM, CSA/CRN, Class 1, Div 1, Groups B, C, D; Class 1, Div II, Groups A-D, ATEX/IECEx Zone 1, II 2 G Ex d IIC T6 …T3, II 2 D Ex tD A21 IP67 T90°C…T300°C.

The rugged ST98 Flow Meter sets the industry standard for performance and value with a reliable thermal mass flow sensor in a smart electronics package. The ST98 operates over a wide flow range from 0.21 to 172 NMPS in air with a standard flow accuracy of +1 percent of reading, +0.5 percent of full scale. It is ideal for a wide range air/gas flow measurement applications including natural gas or methane monitoring. With the addition of HART communications, the ST98 is now a drop-in network replacement instrument for any other HART-compatible flow meter, providing process flow and totalized flow data in a matter of minutes.
