Ronan X-76 Automatic Line Leak Detector with Version X-76 DM-4 Microprocessor and JT-H2 Line Pressure Sensor

AUTOMATIC ELECTRONIC LINE LEAK DETECTOR

Certification	Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%. Leak rate of 0.1 gph at 1.5 times operating pressure* with PD = 100% and PFA = 0%. *Since leak rate varies as a function of pressure, this leak rate and pressure were certified using an equivalent leak rate and pressure, in accordance with an acceptable protocol.
Leak Threshold	0.831 gph for leak rate of 3.0 gph. 0.066 gph for leak rate of 0.1 gph. A pipeline system should not be declared tight if the test result indicates a loss that equals or exceeds this threshold.
Applicability	Gasoline, diesel, aviation fuel, fuel oil #4. Other liquids may be tested after consultation with the manufacturer.
Specification	System tests pressurized fiberglass and steel pipelines. Tests are conducted at operating pressure. System will not function with a mechanical line leak detector installed in the pipeline.
Pipeline Capacity	Maximum of 45 gallons.
Waiting Time	None between delivery and testing. None between dispensing and testing for leak rate of 3.0 gph. Minimum of 2 hours between dispensing and testing for leak rate of 0.1 gph.
Test Period	Response time is 20 seconds for leak rate of 3.0 gph. Response time is 20 minutes for leak rate of 0.1 gph. Test data are acquired and recorded by a permanently installed microprocessor. Calculations are automatically performed by the microprocessor.
System Features	Permanent installation on pipeline. Automatic testing of pipeline. Preset threshold. Single test to determine if pipeline is leaking. Pump shutdown, message display, and alarm activation if leak is declared.
Calibration	Equipment must be checked annually for capability of detecting a line leak of 3.0 gph and, if necessary, calibrated in accordance with manufacturer's instructions.
