G2 Series Industrial Grade Turbine Meters

The G2 Series Turbine meters are self-contained, compact and feature an intergrated display.  This group of meters offers a variety of metal and plastic materials to meet almost any fluid application. Fitting connections include, NPT, ISO thread, Flange, Sanitary and True union. Meters in this group range from 1/2 inch to 2 inch depending on model. Flow ranges start as low as 1 GPM and go to 200 GPM.  Choose the G2 Series when you need good accuracy for a reasonable cost.  These meters are intrinsically safe for Class 1, Division 1 environments. The Tri-Clover model is great in non-3A food processing applications. These meters are cost-effective and are ideal for monitoring, batching and some process control applications.  PVDF meters have no wetted metals and can be used with harsh chemicals such as sulfuric acid and bleach.

Economy Electronic Digital Meters

GPI Economy Electronic Digital Meters are best described as "Application Specific.”   These meters are the choice when economy in monitoring is required. Their accuracy is lower than our other meter families but these meters are perfect in many basic applications. 

01 Series Meters are available in aluminum and nylon.  The aluminum meter comes calibrated from the factory for petroleum fuel. The nylon meter is a simple, rugged, water meter. These two meters come in the 1 inch size only with a flow range of 3 to 30 GPM.

FM-300H/R Chemical Meter mounts at the end of the hose or on a pipe inline. The PBT Polyester housing works well for chemicals. The flow range for this meter is 2 to 20 GPM.

Lube Meters are compact meters used for metering engine oils or transmission fluids. The 1/2 inch meter is available with NPT or BSPT connections. The flow range for this meter is 0.26 to 7.8 GPM.

TM Series meters are an economical choice for water applications. Five sizes of this PVC meter are available.  Choose this meter for measuring water in the 1 to 200 GPM flow range.

Electronics Choices

GPI Electronics come in a variety of types depending on the output required. Output can be as simple as rate of flow to the Wireless system. GPI Electronics can fit almost any signal need.  Output models include:

  • Controllers: Used for batching and Net Use
  • GBT – Batch Controller
  • GRT – Total & Rate Controller
  • 09 Computer Display: Mounts on the meter and provides 2 totals (1 resettable, 1 cumulative), 2 userdefined calibrations and flowrate. Easy to customize in the field.

Indicating Instruments with Output:  

  • GG5 – Pulse Output with Display
  • GX5 – 4-20 mA Output with Display 
  • GA5 - 4-20 mA Output without Display 
  • SC5 - Scaled Pulse 
  • Wireless: The Wireless System transmits signal to receiver without the need of cable. Maximum transmission distance is 300 feet.
