Flow Totalizer
Graphic LCD, Digital RS-232 or RS-485 Interface
The Series GFT2 Flow Totalizer is a microcontroller driven device designed to linearize
the flow meter and controller flow curve plus display the instantaneous flow rate, total,
and accumulated total. The totalizer is intended to be used with analog flow meters and
controllers with analog 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA interface. RS-232 or RS485 digital interface is available.
FEATURES
• Up to 47 different volumetric and mass flow engineering units (including user defined)
• User adjustable LCD back light and contrast level
• Compact design for unit mount, panel mount, wall mount, or field mount
applications
• Low and high flow alarms with programmable action delay
• Free configuration and mounting utility software
• 0.51˝ (13 mm) LCD digits for flow rate, and 0.21˝ (5.5 mm) digits for total
