E <br />Results OPThird Party Standard vat tion <br />Al Point Sensor Liquid Contact Product Detectors <br />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."! <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 QaT Monitoring Systems: Models ILS 350 (serial jBeta 1 <br />Version with Liquid Sensor for Sumps (0794390-2QM <br />Vendor Veeder-Root Enviroamental Products <br />125 Powdpr Forest Drive <br />(street address) <br />(city) <br />(state) (zip) <br />(phone) <br />Detector operating principle: —Electrical Conductivity _Capacitance Change <br />—interface Probe —Product Permeable —Product Soluble _Thermal Conductivity <br />—Pressure Switch —Magnetic Switch -X-Other (Float Switch) <br />Detector sampling frequency: —intermittent _X_Continuous <br />Evaluation Results <br />The detector described above was tested for its ability to detect test liquids in contact with ths- <br />point sensor. 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 />Carnegie Mellon Research Institute.
