YF-S401 Hall Effect Hydroponic Water Flow Sensor Flow Meter Switch is an electromagnetic fluid flow sensor to detect and measure fluid flow speed based on electromagnetic hall effect. In the electromagnetic hall effect sensor type, the fluid acts as a conductor and a magnetic field are made by passing current into a coil outside and around the fluid tube. The inductive voltage is directly proportional to the flow rate. These type of fluid sensor is suitable for destructive and corrosive fluids and liquids.
The YF-S401 flow sensor is made of a plastic valve body, a fluid rotor, and an electromagnetic hall effect sensor. This sensor has two 6mm tube entrance, one for attaching an input fluid tube and another for exiting the detected fluid. It has a high insulation resistance in the range of few megaohms. The YF-S401 sensor is specialized for laser cutting tube or CNC spindle for cooling. Also, it can be used for Coffee Dispenser to fluid control Counter and so on. It can detect and measure a little fluid with accuracy at 0.15 litter per minute up to 3 litter per minute. This sensor can tolerate a hot fluid with 120 degrees Celcius and can well work in a -25℃  up to  80℃ environmental conditions.
