Results of Third Party Standard Evaluation <br /> Point Sensor Liquid Contact Product Detectors <br /> y This form documents the performance of the cable sensor liquid contact leak detection system described below. <br /> The evaluation was conducted by the equipment manufacturer or a consultant to the manufacturer according to the <br /> Third Party Procedures developed according to the U.S. EPA's "Standard Test Procedure for Evaluating Leak <br /> Detection Methods: Liquid-Phase Out-of-Tank Product Detectors."1 <br /> Tank owners using this leak detection system should keep this form on file to prove compliance with the federal <br /> regulations. Tank owners should check with state and local agencies to verify that this form satisfies their <br /> requirements- <br /> Method Description <br /> Name 350 Series UST Monitoring Systems: ModQls ILS 35Q a?,rialu TLS 350 <br /> Version - <br /> 420) <br /> Vendor - <br /> (street address) <br /> imsbu .

The following parameters were determined: <br /> • Detection Accuracy - The measure of sensor response to the presence of liquids. <br /> • Response Time - Amount of time the detector must be exposed to liquid before it responds. <br /> • Recovery Time - Amount of time that passes before the detector returns to its baseline reading <br /> after the test liquid is removed. <br /> • Lower Detection Limit - The smallest liquid concentration that the detector can reliably detect. <br /> • Product Activation Height - The height of liquid to cause sensor activation. <br /> • Specificity - Indicates the level of response, of the detector, to several different liquids. <br /> 1 Carnegie Mellon Research institute.
