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) |
