Description FTB790 Series turbine meters with microprocessor-based electronics offers a durable, compact, high-precision fluid measurement device, with total and rate indication. Information is clearlydisplayed on a large 6-digit liquid crystal display with only 2-point floating decimal for totals from0.01 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 calibrationcurve 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 operatingon an applied voltage of 0 to 60 Vdc. The output is a square wave pulse with an amplitude thesame as the supplied voltage.
The FLSC790-P-DC external power module for the FLSC790-P, allows for 9 to 30 Vdc external power forthe pulse output. Internal batteries in the display can be used as an auxiliary power source.
The FTB790-RK remote kit allows remote mounting of display electronics. This option expands the applications into wider fluid temperature ranges to -40 to 121°C (-40 to 250°F). The LCD display can be mounted up to 90 m (300') from the turbine meter.
The FTB790-RK-FM is an FM approved remote kit. It allows the display electronics to be mounted ina hazardous area up to 30 m (100') from the turbine meter and for fluid temperatures of -40 to 121°C(-40 to 250°F).
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 thestandard position.
