Product description
The flow switch can control a pump, operate a solenoid valve or generate an alarm.
The built-in microswitch is controlled by a paddle placed in running water.
At a certain volume flow (pressure), this movable paddle activates the switching contact. This switching point is adjustable by means of a screw.
Applications
Water and non-aggressive liquid
This flow switch with 1″ connections is suitable for water and non-aggressive liquids.
Included in the delivery are four different stainless steel paddles, respectively 30, 48, 79 and 156 mm long. This allows this flow switch to be used in a range of 0.8...200 m3/h.
This is an industrial-grade flow switch. For air conditioning, refrigeration, boiler and heating systems, building automation, agricultural, sprinkling, fish ponds, etc.
Pipe diameter and water volumes
The flow switch is screwed into the pipe via a thumb fitting. Delivery includes paddles (metal strips) for setting the correct switch value.
The paddle choice depends on pipe diameter (from 0.5 to 8 inches) and the number of cubic metres per hour of water displacement. The manual includes a table with these values.
