 STAN-P-K-VA |
STAN-P piston flow meters are used to measure and control the flow of water, oils, or other liquids. Their operation is independent of their mounting position.
The device is equipped with an orifice plate containing a magnetized piston, placed in a cylindrical tube. The piston is driven by the fluid to be measured and balanced by a compensated spring, enabling reliable operation in all positions.
A magnet integrated into the piston transmits its movement to a remote mechanical needle indicator, providing instant visualization of the flow rate on the scale.
A bistable reed contact, normally open when there is no flow, is mounted on an external slide and closes when the magnetic piston passes. The contact trigger point can be set across the entire measuring range.
The actual flow rate may exceed the set measuring range without damaging the device, but this will increase the pressure loss.
These devices must only be used with fluids that are free of particles and away from any magnetic influence.
