State Water Resources Control Board Page 3of4 low level switch Reset is Automatic Reset time (sec) low and high <1 Detection time (sec) -high level switch Precision- standard deviation 0.004 (in) low and high level Mean detection limit(in) 2.657 Low 11.777 High Specificity Results: Manufacturer and evaluator claim sensors will respond to any liquid. No additional materials tested. Manufacturer's Specifications: Manufacturer states that systems require nocalibration. Annual functional test required. Model 51ODiscriminating Sensor and Model DFR-1 Liquid Level Switch are designed howork with Bmoudreou Models 4D4-4' 5OO' and 5DDCControllers. Model 516 Discriminating Sensor is designed to work with Beaudreau Models 500, 500C, and 512 Controllers. Model 516 Discriminating Sensor will not work with Model 404-4 Controller. Model EOS1 00 Discriminating Sensor is designed to work with Beaudreau Model 522 Remote Monitoring system and Model 522TMonitoring System, and ESiteMonitoring System. Comments: Models 404 and 406 Liquid Level Sensors, Model DFRA Liquid Level Switch, and Models EOS1 00 and 516 Discriminating Sensors are reusable. The polymer strip used in Model 510 Discriminating Sensor is designed to be replaceable if desired. This design allows the end-user to immediately reuse the sensor by replacing the polymer strip, instead of having towait 24to48 hours for the polymer strip ho dry out. Replacement lowers the risk offalse alarms caused bythe use ofpartially dried out polymer strips. Model 516 Discriminating Sensor is designed to be placed in a sensor well in bottom of a containment sump with at least one other sensor mounted higher as a high-water cut-off. Both Models 51Dand 516 Discriminating Sensors were not evaluated for the ability to detect a layer of hydrocarbon on water. 'ode| E[)S1OUhas 5sensing points that can sense fuel orwater over a3.5-inohrange. The highest sensor (lgwe| 5)acts ao a high level switch. If water is detected at level 5, a fuel alarm will be triggered instead of a water alarm. |ffuel isdetected atany ofthe levels, afuel alarm will bmtriggered. The output from the system can be used to shut down the turbines when fuel is present or when water reaches the high level switch. Model 522 Remote Monitoring System: : Evaluation indicates that when threshold |ave|ofK8ode| 4O6LiquidLeve| Senoor' endK8nde|nE[)S1UO' 51Uand 516 Discriminating Sensors 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-35QMonitoring 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 bvModel 522 Remote Monitoring 8yetamcan be recognized by other monitoring systems designed bodetect this output signal. Model 522 Remote Monitoring System was evaluated only using the Veedor-RootTLS'35O Monitoring System. Model 522T Monitoring System: Evaluation indicates that when threshold level of Model 406 Liquid Level Sensor, and Models EOS1 00, 510 and 516 Discriminating Sensors 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 arelease has mccurred). http://www.waterboards.ca.gov/water—issues/programs/ust/leak preventinn/19113/veudorsib... 6/4/2009
