LLP-203 Series Pipeline Line Leak Detector with the TMS2000, TMS3000 and TMS4000 Series
Consoles for Hourly Testing on Rigid, Flexible and Hybrid Pipelines


Certification Leak rate of 3.0 gph @ 10 psi equivalent with PD = 100% and PFA = 0%
Leak Threshold 1.8 gph at 10 psi equivalent. 
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, ethanol blends up through E100, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751, #4 and #6 fuel oil, used oil.
Specification Mystem tests pressurized Fiberglass, flexible, semi-rigid and rigid pipelines. 
Tests are conducted at system operating pressure.
Pipeline Capacity If the desired Bulk Modulus value does not appear in the table, select the next LOWER value. If the desired Charge (system operating) Pressure value does not appear in the table, select the next HIGHER value.
Waiting Time Waiting times after the delivery of product, after product is circulated through the line or after pumping has stopped are not necessary before valid tests can be conducted.
Test Period Response time is dependent on line volume, service pressure, and bulk modulus, and can range from 30 seconds to 13 minutes.
System Features Permanent installation on pipeline. 
Automatic testing of pipeline.
Preset threshold. 
Single test to determine if pipeline is leaking. 
If leak is declared: Programmable for alarm only, or alarm with system shutdown. Programmable for test following pump shutdown only, or hourly.
Calibration Leak Detection system operation must be verified annually in accordance with manufacturer's instructions.
