The OMEGA? FTB-930 & FTB-940 Series turbine meters have male NPT end fittings for easy connections. They are suitable for use with gases with a minimum density of 0.025 lb/ft 3 (air at STP is 0.0752 lb/ft 3 ).These units come supplied with a mating 2-wire connector and can be supplied with integrally mounted FLSC-60 Series signal conditioners to provide 4-20 mA, 0-5 V, or amplified pulse outputs. These turbine gas meters are intended for clean service only; where there is any doubt about the fluid, strainers are recommended.
OMEGA? precision turbine gas flowmeters are designed to measure actual cubic feet or actual volume passing through the meter. Before sizing a flowmeter, it is necessary to convert flow units (i.e., SCFM, LPM, etc.) to actual units. To convert to actual measured volume (ACFM) from standard volume (SCFM), use the following formula:
ACFM = SCFM x 14.7/Pa x Ta/530
where:
ACFM = Actual cubic feet per minute of measured gas flow
SCFM = Standard cubic feet per minute gas flow
Pa = Operating pressure (psia) in = (psig + 14.7)
Ta = Temperature in degrees, Rankine = (°F + 460)
