1-30l / min - 1/2" - Flow Sensor Meter for Liquid, Water - YF-S201

A liquid flow sensor made of high-class PPS material, chemically and mechanically resistant, is used to control external devices. It even reacts to a small flow by generating a high-resolution voltage signal to the controller.

Technical data

Operating voltage: 3.5-24 VDC
Working pressure maximum 17.5 bar
Maximum operating current 10mA
Working temperature -20 to +90 ° C
1/2 inch connections (outer thread diameter 20mm)
Flow: 1-30 Liters / minute
Resolution F = (7.8 * Q) ± 10% Q = L / MIN
Number of pulses per liter of liquid: 468 + - 10%

For example, for a flow of 1 liter / minute, the sensor will generate a square-wave signal with a duty cycle of about 50% and a frequency of 7.8 Hz (+ -10%).
Similarly, for a flow of 10 liters / minute it will be 78 Hz (+ -10%)
