Description
Broil developed and produced plastic helical rotor flow sensor specially for liquid dispensing industries, now a day water dispensing industries use plastic turbine flow sensor its k factor changes with flow rate so for solution we developer helical rotor plastic flow sensor with same pulse k factor for full range also provide very good accuracy and repeatability in full range of measurement.
Performance Data
High accuracy, up to 2.5 bar pressure, independent of viscosity, perfect for 1 ~ 106 mm²/s, low pressure drop compared with other positive displacement meters, high resolution, pulsation free measurement, nonsensitive to pulsating flows resistant to corrosion by advanced materials.
