Water Flow Switch Installation
Before installing the water flow switch remove all power to the control.
Water flow switch installation. Adjust flow paddles to the size of the pipe used. Fit the switch into the space with the water in end towards the device you want to wire. Other general installation rules include. With a hacksaw cut out a section of the pvc part of the water pipe that leads to your device.
An efficient flow switch from grainger can accurately monitor the flow of air steam or liquid then send a signal to a pump to turn itself on or itself shut off. Most water flow switches work by using a paddle usually a physical one but sometimes ultrasonic wired directly to the channel through which water or other liquids will pass. Models are used with oil air water and gases. Refer to the instructions that come with the switch to cut out the right size section.
How does a water flow switch work. Liquid flow switches can be used to help regulate systems such hydronic heating plumbing water cooling equipment liquid transfer water treatment and more. It is recommended that a 50 micron filter be used to protect the internal actuator of the switch. They are single pole double throw spdt and can be installed to turn one circuit from off to on normally open or from on to off normally closed.
Applications include oil flow control low flow detection in cooling lines and high pressure lubrication systems. Shuttle or piston flow switches are sensors with an electrical contact output at a specific flow rate. Place it as level as you can for it to work properly. Electrical connection the switch assembly has three wire connections.
The movement speed of the paddle will indicate the flow rate to the transducer and the transmitter will in turn take this information and convert it to a signal or action. Turn off the fuse to cut the electricity going to the device to which you want to wire the water flow switch. On horizontal pipe it should be mounted on the top to avoid rust or particle accumulation from interfering with its. On vertical pipe it should be mounted where there is an upward flow.
Turn off the water. The flow switch should be mounted six to seven feet above the ground. The water flow switch option wfs is a piston activated in line flow switch which requires filtering of the cooling system water to insure proper operation and long product life. If needed trim the large flow paddle at the arc corresponding to pipe size see figure 1 and figure 2 and install.
