Water Treatment Lime Silo Radar Level Transmitter

When a Virginia municipality needed reliable level measurement of their lime 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 mechanical level sensors that frequently clogged and eventually failed due to corrosion. He said, “We need reliable measurement.” For these reasons, Flowline suggested our non-contact LR85 radar sensor with a PFA antenna, rotational flange and maintenance free measurement. The radar sensor provides reliable level data to the SCADA that controls the chemical feed and alarms for lime powder replenishment. Flowline is reliable level measurement.
