Cali fomia Edition June IMM INCON Intelligent Controls, Inc. TS 1000/1001/2001 (Magnetostrictive Probe) AUTOMATIC TANK GAUGING SYSTEM Certification: Leak rate of 0.2 gph with Po=99.9%and Pry=0.1%. Leak Threshold: 0.1 gph.A system should not be declared tight if the test result indicates a loss or gain that equals or exceeds this threshold. Applicability: Gasoline,diesel,aviation fuel and fuel oil i/4. Other liquids may be tested atter consultation with the manufacturer. Tank Capacity: Maximum of 15,000 gallons. Tanks less than 95%full may be tested. Minimum product level required based on tank diameter is as follows: 48"dia/min 12';64"dial min 14";72"dia/min 15";96'dia/min 17.5"; 126"dia/min.21.5". Waiting Time: Minimum of 6 hours 1 minute between delivery and testing. None between dispensing and testing. There must be no delivery during waiting time Test Period: Length of the test is determined automatically based on quality of test data. Average data collection time during evaluation was 5 hours 10 minutes. Test data are acquired and recorded by a microprocessor. Leak rate is calculated from data determined to be valid by statistical analysis. There must be no dispensing or delivery during the test. Temperature: Probe contains 5 thermistors to monitor product temperature.At least one thermistor must be submerged in product during testing. Water Sensor: Must be used to detect water ingress. Minimum detectable water level in the tank is 0.208 inch. Minimum detectable water level change is 0.011 inch. Calibration: Thermistors and probe must be checked and calibrated in accordance with manufacturers instructions. Comments: Not evaluated using manifold tank systems. Tests only portion of tank containing product. As the product level is lowered,leak rate in a leaking tank decreases(due to tower head pressure). Consistent testing at low levels could allow a leak to remain undetected. EPA leak detection regulations require testing of the portion of the tank system which routinely contains product.TS1000 and 1001 can support up to 4 tanks.TS2001can support up to 8 tanks. California regulations require at least one test per month after routine product delivery or when the tank Is filled to within 10% of the highest operating level during the previous month.
