Switch VM Piston
VM Flow switches are conceived as universal instruments for fluid and gas control in any industrial sector. The passing fluid vertically pushed a magnetic piston, housed inside a rugged valve body The vertical movement is proportional to the flow rate. The piston magnetically activates a microswitch contained inside the adjustable electric head. The piston and flow chamber are designed to guarantee a high functioning stability (0 - 100 cst.) as the fluid viscosity changes. To set the alarm value turn the electric head axially, referring to the diagram displayed on the instrument. The changeover contact may be both used as normally open and as normally closed.
Use/Characteristics
 
- Functioning stability, also with variable viscosity fluids.
- Hermetic separation between flow chamber and electric head.
- No restrictions on assembling position.
- Constant regulation of the set point value.
- Indifference to impurities, due to the valve type structure.
 
The instrument is normally used in industrial operations requiring the control of cooling or lubricating liquids, as well as for transformers, welders, machine tools etc.
