GPI Flomec DP490 and DP525 Insertion Impeller Flowmeters

Great Plains Industries' Flomec DP stainless steel  insertion impeller flowmeters measure the flow of water, fuel, and other low viscosity liquids. When the insertion flow meter is installed, 1/8 of the meter head goes into the pipe, resulting in very little pressure drop.

The DP insertion impeller meter is commonly used for HVAC, hot and chilled water, fire systems, water distribution, boiler and chiller feed water and industrial chemicals.

Key Specifications

  • Simple flow measurement for clear fluid applications
  • Suitable for pipe sizes from 1.5" to 100"
  • Flow ranges from 4 to 780,000 USGM (0.25 to 49000 liters/sec)
  • Intrinsically safe model available
  • DP525 version suitable for hot tap installation
  • Integral 4-20mA output option, quadrature pulse output option and bi-directional flow measurement
