We have a wide range of flow switches incorporating various types of flow meters for many process liquids and gases.
The KOBOLD flow monitor types PSR and PSE are a simple, reasonably priced and reliable monitor of fluid motions.
Depending on the flow velocity/flow through-put, the baffle plate is deflected and it moves the balance arm and 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 for pipe size to 40mm. For bigger nominal pipe diameters these devices are supplied for direct fitting and can be screwed into standard T pieces or reducing pipes. PTFE tape can be used for sealing.
Cooling and lubricant circuits
Dry running protection for pumps
Prevention of low water levels
Monitoring of pipe fracture
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
Baffle plate exchangeable
PSR and PSE versions
PSR made of brass or stainless steel with fitting and female thread for nominal sizes G ¼ to G 1 ½,
8 mm – 40 mm dia. PSE made of brass or stainless steel with external thread for larger nominal sizes from 50 – 200 mm Dia.
