When a California building automation system integrator needed reliable level measurement of their fire sprinkler water supply tanks, they turned to Flowline. In high rises or large buildings, state fire codes typically require secondary water tank systems, capable of supplying 30 minutes of fire suppression if municipal water service is disrupted. In which, the system must have level equipment to detect and automatically refill the tanks when low. The engineer required a reliable non-contact level sensor that’s unaffected by condensation for use with their building automation system. The ultrasonic sensors provide reliable level data to the SCADA which monitors the tanks on each floor and controls their refill. Flowline is reliable level measurement.
