Flow switch suitable for a wide range of flow control applications in both hot and cold liquids

Heavy Duty Flow Switch

The F20 flow switch is a tough but highly sensitive paddle flow switch suitable for a wide range of flow control applications in both hot and cold liquids. The electrical housing of the switch is a separate assembly and locks onto the wet end of the switch. It can be easily and safely removed for servicing, without disturbing electrical wiring. This unique feature and the inclusion of a built in manual override makes the F20 a very versatile flow switch.

The electrical module of the F20 flow switch is completely separate from the process connection and wet end of the switch. The wet end assembly and the electrical module lock together with a single externally accessible screw. This feature allows the flow switch to be disassembled and unscrewed from pipework without the need to disturb electrical wiring. All F20 flow switches are supplied with an extra long glass fibre reinforced polypropylene paddle. The paddle can be cut and shaped as required to suit pipework 20mm (3/4”) or larger.

A unique feature of the F20 flow switch is its built in manual override. This allows the flow switch to be switched on at any time at the press of a button regardless of lack of flow. Using the manual over ride
allows pumps to be manually started at any time by simply pressing the button. It also makes the testing
and commissioning of systems very simple. Our well proven magnetic repulsion system is built into each F20 flow switch and couples the paddle’s movement to the high compliance switch through a double wall of solid material. The result is a high pressure flow switch with no seals, diaphragms or bellows or other points of potential failure.

The F20 is available in stainless steel, dezincification resistant brass or Polypropylene construction. There are models to suit most applications including use in seawater, bore water, acids, alkalis and in many  chemical solutions and fuels. There is also a dedicated dieseline version of the F20 available.
