HVAC Cooling Water Sump Liquid Level Sensor

When Hewlett Packard needed reliable level measurement of the water sumps in their data center, they turned to Flowline. Servers generate tremendous heat, and HVAC cooling systems are required to maintain operational temperature. The reliable collection and transfer of process water to and from the cooling tower is critical to the system, and the operators had experienced agitation and corrosion problems with their previous float level sensors. For this reason, Flowline suggested the use of our non-contact ultrasonic liquid level sensors, mounted in a stand-pipe to eliminate agitation. The ultrasonic sensor provides continuous level data to the PLC, which in turn, monitors the sump level and actuates the transfer pump. Flowline is reliable level measurement.
