VAT only for Spain
Description
The fluid flow causes the displacement of magnetic piston and closes the electrical contact of sensor (reed switch).
The Eicos flow switch FA14B02 of 1/4"G port is ideal for low flows of water. The sensor has an operation range that allows to adjust the ideal flow of liquid to be detected in application.
The sensor works Normally Open (NO), with ON signal when the flow (liters per minute) is higher that the sensitivity adjusted in the sensor and OFF signal when the flow decreases below the set point.
Output connection in 1.50m wire.
