GPI Digital Flow Meter / Totalizer Rental
- 1-10 GPM (1/2" inlet/outlet) or 5-50 GPM (1" inlet/outlet) models available.
- Displays flow rate and cumulative flow.
Information is clearly displayed on a large 6‑digit LCD readout with two‑point floating decimal for totals from .01 to 999,999. All operations are easily accessed with the two buttons on the front panel. The CMOS, microprocessor‑based electronics have extremely low power requirements and data retention capabilities in both RAM and ROM.
Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This pulse data is translated from the turbine into calibrated flow units shown on the computer's readout.
All GPI turbines are designed to measure flow in only one direction. The direction is indicated by the arrow cast‑molded in the turbine outlet. If the computer display is upside down, remove the four screws, turn the display 180° and reinstall the screws.
