Detecting cooling water flow
By detecting flow, part absence can be detected in addition to the blockage of water flow due to debris buildup. Also, by monitoring the flow, it is possible to predict the need for maintenance.
The FD-M Series Non-Wetted Electrode Electromagnetic Flow Sensor is the first factory automation flow sensor to adopt a free-flowing structure. Unlike floating-element and paddlewheel devices, the free-flowing structure of the FD-M Series has no moving parts or obstructions in the flow pipe, greatly reducing the risk of clogging. With no moving parts, the sensor is not subject to mechanical wear, which ensures a long service life. There is also virtually no pressure loss in the pipe, so the pump uses even less energy. Unlike conventional electromagnetic systems, this device detects liquid from outside the pipe, making it highly resistant to insulating deposits inside the pipe while minimizing maintenance. Two sensor types are available: one with a separate amplifier that allows flow rate monitoring using the LEDs on the sensor head and one with an integrated amplifier and a dual-row digital display for easy setup.
