Flow sensor CP3/4-B
Liquid flow sensor designed to read the flow of water or other liquid with a capacity of 2.5 to 30 L per minute. High sensitivity allows detection of even small liquid flows. Mounting 2x 3/4" external thread.
pic Flow sensor CP3/4-B
The sensor under the force of liquid flow causes the reed switch to short circuit. Made of brass body. Mainly used for water heaters, boilers, water dispensers, coffee makers, vending machines, steam equipment, water systems, water treatment equipment, cooling systems, mechanical equipment, instrumentation, pharmaceutical equipment or other industrial automation projects.
