plastic helical rotor water flow sensor is positive displacement base principle with low pressure loss, high accuracy and not depend on viscosity so its best option for dispensing and metering application for all liquid.

broil developed and designed helical rotor plastic water flow sensor with pulse output, fully inhouse facility including injection moulding machine and owen mould and tools,

Plastic flow sensor is best for water and liquid automatic dispensing machine, its also best for water AMR SYSTEM,

Helical rotor water flow Sensor are positive displacement meters with a very favorable low pressure drop behavior.
therefore perfectly suited for the flow measurement of very high viscosity fluids.
Due to wide measuring ranges, high accuracy and resolution helical flow meters are an excellent choice for
laminating systems, painting systems, adhesive dispense systems, as well as batching systems for various fluids.
