When a Virginia municipality needed reliable level measurement of their lime dosing silo, they turned to Flowline. With 10-14 grains per gallon, the local water supply is unusually hard. To combat this, the treatment plant doses calcium hydroxide into their clarifiers, which raises the pH and precipitates the ions that cause hardness. There the plant operator was dissatisfied with the prior bob mechanical level sensors that frequently clogged and eventually failed due to corrosion. As he said, “I need reliable, maintenance-free level measurement.” For these reasons, Flowline suggested our non-contact 80 GHz radar sensors with corrosion resistant PFA antennas, that are easy to configure and inspect via our LevelTap App with secure Bluetooth. The radar sensor provides reliable level data to the SCADA system that controls chemical feed and alarms for lime powder replenishment. Flowline is reliable level measurement.
