Liquid Flow Switch
Liquid Flow Switches series
Flow control of water and aggressive media (depending on model).
Alarm signal of flow shortage. Available in brass for normal media, and in stainless steel AISI316L for aggressive media.
Well-suited in pipes of general industrial plants:
- heating and air conditioning systems
- refrigeration systems
- heat pumps

The flowswitch can be installed in every position far from elbows or throttlings, with arrow on flow direction. If pipe is vertical, recalibrate range to balance paddle weight.
If the device is downwards mounted take care to slags, and apply it in a straight pipe far from filters, valves, etc with length at least 5 times the diameter of pipe upstream and downstream the unit.
