When a Midwest commercial HVAC maintenance contractor needed reliable level measurement of their clients cooling tower sumps, they turned to Flowline. Under continual evaporation, cooling towers require frequent water replenishment, and the most common associated failure is a corroded or scaled float or conductance level sensor. To fix this, the contractor required a non-contact level sensor that can be used as a switch with relay contacts or a transmitter with an analog output, thus enabling them to replace any maintenance configuration they encounter. For these reasons, Flowline suggested our multi-function ultrasonic sensors that are perfectly applied in small sumps. The ultrasonic sensor provides reliable level data to the controller that monitors the sumps and controls the fill valves. Flowline is reliable level measurement.
