Results are typical for the other sensors in the 857060-xxx and 857080-xxx <br /> series, regardless oflength and programmability opUonm. <br /> All sensors are based on the use of a magnetostrictive sensor that is equipped with two floats.The lower float will only <br /> float onwater.The upper float will float onfuel omwell mmwater. <br /> Results for the"water alarm"threshold will vary based upon programmed alarm levels. <br /> The"fuel alarm"iobased upon afixed threshold and innot programmable. <br /> Systems containing these sensors can be programmed to alarm continuously and to shut down the dispensing system. <br /> Sensor will issue an alarm if it is raised from the bottom of the containment vessel. <br /> Sensors are reusable. <br /> Vendor claims sensors are easily removable, cleaned, and reinstalled if an alarm is triggered or for periodic testing. <br /> Comparison of TLS-450 with TLS-350 series console showed comparable results when evaluated with representative <br /> sensors. <br /> VoadepRoot Evaluator: Ken Wilcox Associates <br /> 125Powder Forest Dr. Tel: (818)443'2484 <br /> Simsbury, CT 08070-2003 Dates ofEvaluation: 5/17/04,4/21/05, 6/27/05. 4/28/07 . <br />
