Fluid Components International, a global company committed to meeting the needs of its customers through innovative solutions to the most challenging requirements for sensing, measuring and controlling flow and level of air, gases and liquids, recently announced the launch of ST51, a mass flow meter that provides excellent measurement accuracy in an explosion-proof instrument that’s safe, simple to install, requires almost no maintenance and that offers an economical low lifecycle cost.

With its no-moving parts thermal dispersion mass flow sensing element, the ST51 Flow Meter provides direct mass flow measurement of gas without the additional equipment required with other flow measurement technologies.  Its non-clogging sensor design operates over a wide flow range with low-flow sensitivity, and the meter’s calibration is matched to the user’s actual gas composition and installation conditions.  This proven, rugged design is ideal for wet, dirty coal mines and coal bed methane gas recovery environments.

According to FCI, the ST51 Flow Meter is ideal in mining methane gas recovery applications.  It features an 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. In addition, the ST51 operates over a wide turndown range of 100:1, which is essential due to the variable gas flows in mining operations. It operates at temperatures from 0 to 250°F (-18 to 121°C) and withstands pressures up to 500 psig [34 bar (g)].3 to 400 SFPS (0.08 to 122 MPS), and repeatability of ±0.5 percent of reading.
