Beskrivelse
FTB790 Series turbine meters with microprocessor-based electronics offer 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 two-point floating decimal for totals from .01 to 999,999. All operations are easily performed with two buttons for simplicity. The basic unit and display are powered by two lithium batteries, providing up to 4000 hours of actual use. Automatic “on” and “off” save battery life. Manual “on” allows view of the display on demand. Cumulative total, batch total and rate of flow are standard. A fifteen-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-ND-P) 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 three-wire connection.
The FLSC790-MA, 4-20 mA output or 0-5 Vdc output for rate indication. Requires field calibration. The 4-20 mA dc is a two-wire system requiring 8-30 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. A two-wire connection is required with an 820Ω (min) pull-up resistor. The FLSC790-P-DC, external power module for the FLSC790-P allows for 9-30 Vdc external power for the 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 , the LCD display can be mounted up to 90 metres from the turbine meter. The FLSC790-BATT is the replacement lithium battery for the display electronics. Batteries provide 4000 hours of actual use.
