HGLC Oval Gear Flow Meter

HGLC Oval Gear Flow Meter

Oval gear flow meter is used for the continuous and intermittent flow measurement, it is a kind of positive displacement flow meter, features as follow:
● For fluids with high viscosity and without corrosion
● Easy installation, no requirement to Straight pipe length at upstream / downstream
● High accuracy
● Mechanical counter
● Can be integrated with Pulse-output transmitter or Analog current-output transmitter (on request)
● Communication option for electronic transmitter: RS485 or HART (on request)
