When a Virginia manufacturer of foam core signs needed reliable level measurement of their resin bulk storage tanks, they turned to Flowline. Urea and formaldehyde resins are blended into fillers, coatings and adhesives that provide structure to their products. Highly sticky, plant operators used ultrasonic sensors in these applications, but they became intermittent as the level approached the bottom of the tank. This was caused by vapor and the resulting absorption of the acoustic signal. For this reason, Flowline suggested the use of our pulse radar level sensors that are unaffected by vapor, and ideal for coating media like resin. The radar sensors provide continuous level data to the PLC, which in turn, monitors the tanks and alarms for replenishment. Flowline is reliable level measurement. |
