*TLS-4 8601 Series testing did not include testing with ethylene glycol . Evaluator expects comparable results from previous testing with other consoles listed.

Comments:
Manufacturer states that Sensor 794380-304 is installed near the bottom of a brine reservoir. An alarm is triggered if the brine level falls below the threshold level of the sensor.
Manufacturer also states that the sensor withstands removal and replacement from the reservoir without damage to the sensor.
The testing conducted for this evaluation determined the sensor's response to brine only. The evaluator states that other liquids would also produce an alarm if the sensor threshold is exceeded. These thresholds would be slightly different for different liquids due to the differing densities. These liquids, and the threshold for each, have not been determined at this time.
Comparison of TLS-450 with TLS-350 series console showed comparable results when evaluated with representative sensors.
