When United Technologies in Connecticut needed reliable level measurement of the chemical feed systems supporting their engineering lab facility, they turned to Flowline. With building equipment, processes and critical testing to protect, the water circulating throughout the HVAC, boiler and chiller systems is constantly treated to remove biological pathogens, eliminate scaling and inhibit corrosion. The chemicals are corrosive or coating in nature, and the maintenance team was often replacing or cleaning the previous float level switches. For this reason, Flowline suggested our non-contact PVDF ultrasonic level sensors that provide maintenance free level measurement of chemical feed tanks. The ultrasonic sensors provide reliable level data to the PLC, which monitors the tanks and alarms for chemical replenishment. Flowline is reliable level measurement.
