We produce various flow swich and widely used for gas and liquid. and below is the mainly model.
Features:
good repeatability
hermetic separation of electrical and hydraulic components
low pressure loss
not include the bellows
corrosion resistant
magnetic switch.
Application:
gaseous /liquid
The flow switch for ground-source heat-pump is mainly applicable to industrial automation/mechanical equipment/air compressing industry/ refrigeration and air-conditioner. The magnet not contact with flowing water, so can normally work in sewage discharging system.
