Specificity Results:
Manufacturer and evaluator claim sensors will respond to any liquid.Manufacturer's Specifications:
Manufacturer states that system requires no calibration.Comments:
Sensors are reusable.

Model 522 Remote Monitoring System:
Evaluation indicates that when threshold level of Model 406 Liquid Level Sensor was reached, Model 522 Remote Monitoring System produced (1) an audible and visual alarm and (2) an output signal that was recognized by a Veeder-Root TLS-350 Monitoring System.
The TLS-350 Monitoring System produced an alarm within 10 seconds, and displayed and printed a notice of alarm and alarm time.
Manufacturer states that the output signal produced by Model 522 Remote Monitoring System can be recognized by other monitoring systems designed to detect this output signal.
Model 522 Remote Monitoring System was evaluated only using the Veeder-Root TLS-350 Monitoring System.

Model 522T Monitoring System:
Evaluation indicates that when threshold level of Model 406 Liquid Level Sensor was reached, Model 522T Monitoring System will generate a visual (LCD readout and LED “alarm” lamp) and audible alarm and also open up to three normally closed relay contacts.
By using a Model 522R Relay, the system can use these normally closed relay contacts to control power to turbine pumps. Alternatively, the normally closed relay contacts can be used to send fuel alarm information to a Veeder-Root TLS-350 for both positive shutdown and additional alarm notification (such as a printout showing the date and time that a release has occurred).
