Main Specifications

  • Housing Material: Aluminum
  • Meter Body Size: 4"
  • Connection Size: 4"
  • Connection Type: NPT Female
  • Design: Oval Gear - Alum. - Pulse Out Only (145 PSI)
  • Flow Range: 20 - 400 GPM (75-1500 LPM)

Features & Benefits

Excellent for applications with fluctuating or multiple viscosities - No field calibrating required; Accuracy: ± 0.5% Of Reading; Up to 1,000 cps Viscosity; No straight pipe requirements; Bi-directional; PPS Rotors are immune to galling (adhesive wear); PPS Rotors produce less noise than metal rotors


Metering clean fluids such as Oils, Grease, Fuels, Fuel Oils, Lubricating Liquids

Application Notes

The meter may be mounted horizontally or vertically but must be mounted so the rotor shafts are in horizontal plane (see manual), For viscous liquids the maximum allowable flow may need to be reduced to ensure the pressure drop across the meter does NOT exceed 15 PSI, Viscosities <3cps, min. flow range is 10% of maximum flow range, Line must be full (no air) for proper accuracy
