THEORY & STRUCTURE

Plug-in installation.Mechinical flow switch .Built-in micro trigger switch.

 

FETURES

Can measure the 2-way flow in pipeline,minimal pressure loss, good repeatability, dirt-resistance.Hermetic separation of mechanical.At the time of delivery is accompanied by 5 baffle plates, on the large diameter pipeline with low velocity or not full,the user can flexibly use according to the actual situation.The same kind of switch can be used for various pipeline.

FUNCTIONS

By detecting the pipeline has or no flow to open or close a circuit. It is usually used in heating, air conditioning, refrigeration, water treatment, water supply, industrial added system and etc. Can control equipment such as: water pump, compressor, combustor, cold water machine, electric valve, alarm equipment, industrial attached equipment and etc; In the heating system, its role is particularly important, when the boiler system backwater flow too low or no flow, it can be quickly closed burner boiler system, to prevent dry burning, over temperature, avoid the frequent involvement of other temperature control element.
