Installation Method of water flow switch in water system
The water flow switch generally has three contacts, normally open and normally closed. Normally, it is connected with normally closed contact. When there is water flow, the contact is closed. During commissioning, the commissioning personnel will set the contact disconnection point exactly at the minimum flow required by the unit. When it is less than the set value, stop the main chiller, refrigeration and water pump.
