Flow switches for insertion installation / Metal version for industrial applicat
型號：Type VH780- Universal flow switch for DN 32...200
- Adjustment to nominal diameter and setpoint setting by selection of the baffle flag
- High switching currents due to micro switch as signal transmitter
-
SIKA flow monitors monitor the liquid flow of low-viscosity media in pipelines. Typical applications are:
- heating systems
- cooling circuits
- lubrication circuits
- heat pumps
- water-cooled welding equipment
- compressors
- chemical, pharmaceutical and food industries
- cleaning and environmental protection systems
The flowing medium hits the baffle flag attached to the end of a paddle. The paddle is deflected by the resulting dynamic pressure and actuates a micro switch.
