Case Study: Pulse Burst Radar Transmitter Eliminates False Alarms in Sodium Hypochlorite Tanks

Many water processing plants have implemented level control instrumentation to help achieve critical operational goals. This case study demonstrates how the use of a pulse burst radar transmitter in sodium hypochlorite tanks can help maximize safety – and minimize maintenance costs.

The Challenge
Pulse Burst Radar Transmitter on Sodium Hypochlorite TankA water filtration plant in Washington was using another vendor’s ultrasonic unit to measure level in its 16-foot tall sodium hypochlorite tanks, but was experiencing excessive false alarms due to the loss of echo and spiking during the off-gassing process. This issue usually occurred when tanks were in the low-level position and happened so frequently that plant employees had begun to disregard the alarms – without even checking the tanks to see if there was an issue.

The Solution
Due to recent technological advancements, pulse burst radar has become an affordable solution that many companies are now using in simple, daily applications. A Magnetrol® Model R82 pulse burst radar transmitter was installed in one of the sodium hypochlorite tanks to allow plant employees to evaluate its ability to provide reliable measurement in this challenging environment.

The Results
During the evaluation period no false alarms occurred, which eliminated the safety concerns associated with employees ignoring frequent nuisance alarms. As a result, company management installed four R82 units with ETFE antennas for chemical compatibility, and is considering adding R82s to other level measurement applications across the plant.
