Product Detail

Flow Sensor is the presence or absence of flow through the output switch control signal 
to the water sensor switch, the main switch signal. Divided into specific types normally 
open and normally closed type, in the main water control work flow monitoring role to 
play. Water flow switch and relay use with the usual components of the water control 
system, easy to use, no power is the flow switch on.

Mainly used for water heater, boiler, water dispensers, coffee machines, hot card 
machines, steam equipment, water system, the campus card sales, selling self-help 
water systems, water treatment equipment, cooling systems, mechanical equipment,
 instrumentation, pharmaceutical equipment.

1, flow sensor installation environment to avoid strong vibration, and shaking with the 
local magnetic environment, in order to avoid the flow switch malfunction. In order to 
avoid particles, debris into the water flow switch must be installed in the inlet filter. 
2, when the magnetic material close to the water flow switch, its characteristics may change. 
3, flow sensors, relays must be compatible with use, as less power reed switch (typically 
10W and 70W) easy to burn. Relay maximum power 3W, 3W power will be greater than 
the normally open and normally closed phenomenon.

Periodically clear the guide rod and float on the dirt (as the media cycle may be). Check for 
the loose buckle
