When a Midwest composite material manufacturer needed reliable level measurement and control of their resin storage tanks, they turned to Flowline. The company binds various materials with resin that they manufacture, heat and store onsite for daily production. Formaldehyde based resin is highly vaporous, especially when agitated during tank filling. At that time, operators experienced intermittent measurement from ultrasonic level sensors due to the attenuating effects of vapor on acoustic signals. They also wanted a high level shut-off for spill prevention. For these reasons, Flowline suggested the use of our radar sensors that are unaffected by vapor, and a Switch-Pak high level controller for pump shut off safety. The radar sensor provides continuous level data to the PLC, which in turn, monitors the storage tanks and controls the process. Flowline is reliable level measurement.
