Thermal Mass Flow Meters Reduce Cost Of Measuring Flow Of Natural Gas

Natural gas is the feedstock supply for butane, ethane, and propane, as well as a component in the production of ammonia and methanol. The manufacturing of antifreeze, fabrics, fertilizer, plastics, and pharmaceutical depend on it.

FCI’s inline ST75A Flow Meter is suitable for the estimation of natural gas, other industrial specialty gases, and air in line sizes from 0.25 to 2 inches. It features a stable-state thermal dispersion mass flow sensing element with platinum RTD’s in equal mass thermowells for years of correct, trouble-free service.  It may be calibrated to weigh gases over a wide stream range from 0.04 to 559 SCFM (0.07 to 950 NCMH), relying on line measurement.

For variable plant demand cycles due to small batch or other steady process manufacturing requirements, the ST75A Flow Meter is factory preset to 100:1 turndown. It has highly reliable accuracy to ±1% of reading with ±0.5% repeatability.  Engineers and technicians can depend upon this meter for precise circulation control of gases to make sure high-quality products from batch or steady processes or in production activities.

The rough design of the ST75A Meter’s flow aspect features no-moving elements for superior reliability.  This distinctive model provides extra confidence where process safety is a big worry with other kinds of meter expertise, which depend on movable parts that can break over time in high turndown applications.

The Version ST75A flow meters are made with a selection of mounting configurations.

They feature a digital screen and are additionally available with elective transmitter distant mounting capabilities for dangerous plant conditions.
