There are Hall and Optical Flow Sensor can chosoe.

1.Hall effect sensor based water flow switch, a turbine wheel embed with magnet is placed on a closed plastic envelop and a Hall effect sensor placed, When the water flows through the pipeline, it makes the turbine wheel to rotate and hence the magnet flux interferes the hall sensor, the rate of interference is depends on the speed of water flow, so the hall effect sensor produce pulse signal output, this pulse output can be calculated as water volume.

Food safe flow meters have been widely used for pharmaceutical, food and other industries.When used for food grade application,the pipe size of hall effect flow meters are usually not over 30 mm.
Because stainless steel hall effect flow sensor is expensive, it is firstly recommended to consider food class plastic hall effect flow sensor.

2.The flow rate of the medium through the Micro Infrared Flow Switching is large or small, so the number of signals generated is nonlinear. Whether it is a volumetric or a velocity flow meter, as long as the amount and speed of the flowing medium change, nonlinearity exists objectively. The electronic part of the photoelectric flow meter compensates the curve of different conditions of the medium, and the measurement algorithm changes with the change of flow rate and flow rate.

The Optical Flow Meter FM-PS2130 is compact, versatile, easy to install and small in installation size. No need to compensate for gaps, sensors with high precision measurement, high repeatability measurement and high positioning accuracy, long stroke and long life.
