DIGITAL SENSOR — POSITIVE DISPLACEMENT METER (DIGITAL)

Plastic Helical Rotor Flow Sensor & Meter

Same pulse factor, full range, every time.

BROIL developed and produced a plastic helical rotor flow sensor specially for liquid dispensing industries. Where plastic turbine flow sensors suffer a K-factor that changes with flow rate, BROIL's helical rotor plastic flow sensor holds the same pulse K-factor across the full range — delivering very good accuracy and repeatability throughout the measurement range.

01 · Performance

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, non-sensitive to pulsating flows, resistant to corrosion by advanced materials.

02 · Where it's used

Markets & Areas of Application

Very good for water ATMs, water dispensing, tea / coffee / wine / juice and other food liquid measurement and dispensing. Also fats and oils with varying viscosities, water / glycol mixtures, and any viscous liquid where viscosity changes with temperature.

03 · Why choose it

Advantages

✓Direct plug-in digital LCD readout with reset/cal buttons

✓Three output sensor options to match your controller

✓Low pressure drop compared with other positive-displacement meters
