Fluid Components’ ST51 Mass Flow Meter helps mine engineers and operators recover coal mine methane as a fuel resource and reduce the effects of dangerous greenhouse gases.
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.
The design is ideal for wet, dirty coal mines and coal bed methane gas recovery environments.
Coal mining operations are a major contributor to the greenhouse gas pollution that results in global warming.
There are three major sources of coal mine methane: degasification systems (drainage) both pre-mine and gob, ventilation air (VAM) and abandoned or closed mines.
As requirements for pollution abatement increase, coal mine methane gas is an increasingly attractive fuel source for co-gen electric power.
Precise measurement of methane gas also is required for methane oxidizer systems and to provide data for incentive credits.
The ST51 Flow Meter 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.
It is suitable for line sizes from 2 to 24 inches (51 to 610 mm) diameters.
The ST51 Flow Meter 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.
