When a Kentucky municipality needed reliable level measurement of their aluminum sulfate bulk storage tanks, they turned to Flowline. During the hot summer months, blooms of harmful blue algae grow in lakes and reservoirs. To combat it, they utilize spray boats that apply aluminum sulfate, a powerful flocculant that safely removes blue algae. Prior to dispatch, boats are trailered to a bulk tank, where they fill up the IBC spray tank with chemical. The operator complained that past ultrasonic level sensors became intermittent during peak humidity, and this resulted in untimely chemical shortages when they needed it most. Based on this, Flowline suggested our reflective ultrasonic sensors that are unaffected by humidity and the daily condensation cycles in the tank. The ultrasonic sensors provide reliable level data to the SCADA, which monitors the bulk tanks and alarms for alum replenishment. Flowline is reliable level measurement.
