Description

Description

The FTB930 series is being discontinued. Please see the series as a possible alternative or contact our Flow and Level Engineering department.

The trodeks® 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.

trodeks® precision turbine gasflowmeters are designed to measureactual cubic feet or actual volumepassing through the meter. Beforesizing a flowmeter, it is necessary toconvert flow units (i.e., SCFM, LPM,etc.) to actual units. To convert toactual measured volume (ACFM)from standard volume (SCFM), usethe 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)
