Overview

Description

The fluid flow causes the displacement of magnetic piston and closes the electrical contact of sensor (reed switch).

The Eicos flow switch FE14B04-M12 of 1/4"G port is ideal for low flows of oils. 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 male M12 plug (not included with sensor).

For water applications, see the model FE14B02-M12.

Liquids with magnetic particles will cause deposition/magnetic sedimentation and it will prejudice the operation of the sensor. Use magnetic filter before the sensor.

Liquids with encrustation particles and/or solids require tests.

Installing the snubber filter extends the lifespan of the sensor’s electrical contact.

Never connect the sensor directly to a motor, pump, lamp or any other load over 20W.

Always use a contactor or relay.

Troubleshooting

DIAGNOSIS	ACTION
1) The electrical contact keep on closed WITHOUT flow.	Check if there si overload; Test with an ohmmeter; Open the plug and check if the piston is not blocked.
2) There is flow and the electrical contact remains always open.	Adjust the sensitivity; Check the electrical contact with an ohmmeter; Possible overload that damaged the electrical contact.
