Great Plains Industries G Series Precision Turbine Flow Meter

Precision Turbine Flow Meter
G Series

The High Precision Meter line is the most accurate of the GPI Turbine Meters and includes a traditional design. These meters come in a variety of sizes and fitting options including BSP, ISO, NPT and ANSI Flange fittings. The GSCPS in this section carries the 3A Sanitary Rating.

Sensor Options:
• Low Drag Pickup (1/2 in. turbines)
• Standard Pickup (3/4 to 3 in. turbines) Electronics Options:
• GG510 (Display with Pulse Output)
• GX510 (Display with 4-20 mA Output)
• GA510 (4-20 mA Output)
• SC510 (Scaled Pulse Output)
