FTB380 Series turbine meters with microprocessor-based electronics offers a durable, compact, highprecision fuel 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 4000 hours of use. Automatic "on" and "off" extend battery life. Manual "on" allows view of the display on demand. Cumulative total, batch total, and rate of flow are standard. A singlepoint field calibration curve can be stored in memory.
The turbine meter can also be ordered without display electronics. A special pulse output module (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 Dislay
The FTB790-RK-FM is an FM approved remote kit. It allows the display electronics to be mounted in a 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 4000 hours of use.
The FLSC790-90D is a 90° mounting adaptor designed to allow displays to be mounted 90°from the standard position.
