The KOBOLD flow monitor types PSE and PSR are simple, reasonably-priced and reliable monitors of fuid motions.
Depending on the flow velocity/flow throughput, the baffle plate is defected and it moves over the balance arm the permanent magnet into the operating range of the reed contact mounted outside the process fluid.
The leaf spring, which also serves as a support for the balance arm, forces the baffle plate back to its rest position when there is no flow. KOBOLD baffle plate flow monitors are supplied compley assembled with pipe length up to nominal size 40. For bigger nominal pipe sizes the devices are supplied without pipe length for direct fitting and are screwed into standard T pieces or reducing pipes. PTFE tape is used for sealing.
應(yīng)用Applications
Cooling and lubricant circuits
Dry running protection for pumps
Prevention of low water levels
Monitoring of pipe fracture
Special advantages
Pressure-resistant, forged case for model PSR-xx08...PSR-xx25
Baffle plate system made of spring stainless steel. This precludes bending of paddle even with flow rates well outside the switching range
