Green energy and pollution monitoring

The FCI ST51 and ST98 Flow Meters are used to deliver accurate flow measurement in green electric power co-generation and pollution monitoring/control applications.

Featuring a rugged, no-moving-parts design, the flowmeters are suitable for hazardous plant environments requiring biogas capture and recovery systems for power generation and pollution control.

The flowmeters 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 good performance, low maintenance, long life and a low life cycle cost.

The ST51 is designed specifically to measure biogas, digester gas and all methane composition gases including natural gas. It features a thermal mass, insertion-style flow element with flow accuracy to ±1% of reading over a broad flow range from 0.08 to 122 mps, and repeatability of ±0.5% of reading. The flow element is available for use in line sizes from 51 to 610 mm diameters. It operates over a wide turndown range of 100:1, which is essential due to the variable gas flows in wastewater treatment. It operates at temperatures from -18 to 121 °C and withstands pressures up to 34 barg.

The rugged ST98 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% of reading, +0.5% of full scale. It is suitable for a wide range of 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 flowmeter, providing process flow and totalised flow data in a matter of minutes.
