When a Midwest manufacturer of agricultural and turf chemicals needed reliable level measurement of their urea storage tanks, they turned to Flowline. Urea is widely blended into fertilizer and animal feed products as a safe source of nitrogen that improves crop yields and livestock metabolisms. Operators previously replaced sight glasses with Flowline ultrasonic level sensors on their smaller ammonia and hydrochloric acid tanks, and they wanted to do the same on their taller urea tanks. But urea is exceptionally vaporous, and ultrasonic sensors would not be reliable, due to the vapor’s attenuation of their acoustic signals. For this reason, Flowline suggested the use of our radar sensors with corrosion resistant, PTFE antenna shields that are unaffected by extreme vapor. The radar sensors provide continuous level data to the SCADA system, which monitors the tanks, and alarms for replenishment. Flowline is reliable level measurement.
