- Accuracy Value FTB-791: ±2% rdg
FTB790 Series turbine meters with microprocessor-based electronics offers a durable, compact, high-precision fluid measurement device, with total and rate indication. Information is clearly displayed on a large 6-digit liquid crystal display with only 2-point floating decimal for totals from 0.01 to 999,999. All operations are easily performed with only 2 buttons.
The basic unit and display are powered by 2 lithium batteries, providing up to 5 years of use. Cumulative total, batch total, and rate of flow are standard. A single-point field calibration curve can be stored in memory.
The turbine meter can also be ordered without display electronics. A special pulse output model (FLSC790-P-ND) must be ordered to obtain an open collector current sinking output operated on 9 to 35 Vdc. The output is a square wave pulse with a 3-wire connection.
Accessories for Turbine Meters With the Display:
The FLSC790-MA provides a 4 to 20 mA or 0 to 5 Vdc output for rate indication. The output module requires field calibration. The 4 to 20 mA dc is a 2-wire system requiring 8 to 30 Vdc power (24 Vdc recommended).
The FLSC790-P pulse output module provides an unscaled open collector sinking output operating on an applied voltage of 0 to 60 Vdc. The output is a square wave pulse with an amplitude the same as the supplied voltage.
The FLSC790-P-DC external power module for the FLSC790-P, allows for 9 to 30 Vdc external power for the pulse output. Internal batteries in the display can be used as an auxiliary power source.
The FLSC790-BATT is the replacement battery for the display electronics. Batteries provide 5 years of use.
The FLSC790-90D is a 90° mounting adaptor designed to allow displays to be mounted 90° from the standard position.

What are the allowable mounting orientations? Vertical / flow up, vertical / flow down, horizontal?
Thank you for your inquiry about the inline flow meter. The orientation can be mounted in any position, yet, in a vertical position, the flow must go from floor to ceiling and must be full of flow at all times.

can these be utilized with nozzles?
The FTB791 requires a laminar flow in order to work properly. You cannot mount this sensor right before a nozzle. This sensor needs a straight pipe before and after the sensor. The FTB791 needs at least 15 inches of straight pipe before and 10 inches after the sensor. Please contact our Tech Support or flow@omega.com so we can fully understand your application to further advise as you need. Thank you!
