Hazardous Alum-Sulfate Tank Level Measurement
When a Washington state municipality needed a reliable level measurement of their aluminum sulfate tanks, they turned to Flowline. Aluminum sulfate is a highly acidic, hygroscopic compound used as a water treatment filter agent. The soluble crystals bind or clump with impurities creating flocs that settle out and to be more easily removed from the system, increasing downstream filter efficiency.
In high concentration, aluminum sulfate can have a pH value as low as 2. The plant operators experienced a shortened level of sensor life and required a non-contact, corrosion-resistant sensor. Additionally, the tanks are in a hazardous area due to methane, and they needed intrinsic safety. For these reasons, Flowline suggested the use of our intrinsically safe ultrasonic sensors that are ideal for corrosive chemical feed applications.
The ultrasonic sensors provide continuous level data to the SCADA, which monitors and controls the chemical feed process. Flowline is reliable level measurement.
