The KOBOLD flow monitor types PSE and PSR are simple, reasonably-priced and reliable monitors of fluid motions. Depending on the flow velocity/flow throughput, the baffle plate is deflected and it moves over the balance arm the permanent magnet into the operating range of the reed contact mounted outside the process fluid.
