Caldon PF2000 Pipeline Leak Detection System for Bulk Pipelines

Line Leak Detection Method for Airport Hydrant and Field Constructed Systems

Certification Leak rate of 10 gph at 100 psi with PD > 95% and PFA < 5%. 
(EPA defined equivalent 3.0 gph at 10 psi).
The USEPA has not set a minimum detectable leak rate for large diameter pipeline systems (airport hydrant systems) at the time of this evaluation.
Leak Threshold 8 gph. 
A pipeline system should not be declared tight if pressure decay or change in rate of decay in protected segment indicates a leak that exceeds this threshold.
Applicability Gasoline, diesel, aviation fuel, fuel oil #4.
Specification System tests fiberglass or steel piping up to 18 inches diameter. 
Tests are normally conducted at operating pressures of 50 to 150 psi, but system may not work at pressures less that 75 psi, and may need to be 100 psi or higher. 
System may be used on pipelines pressurized up to 400 psi
Pipeline Capacity Maximum of 212,000 gallons. 
Evaluation conducted on straight piping runs with capacities to 106,000 gallons.
Waiting Time None between delivery and testing. 
None between dispensing and testing.
Test Period Variable up to 15 minutes.
System Features Permanent installation on pipeline. 
Automatic testing under static conditions. 
Preset thresholds. 
Single test to determine if pipeline is leaking. 
Message display or printout, alarm activation if leak is declared. 
Test data acquisition and calculation by system's computer.
Calibration System must be checked annually and, if necessary, calibrated in accordance with manufacturer's instructions.
Comments According to vendor, system works in a complex piping network, can detect leaks developed between static test times, and is capable of detecting gradually increasing leaks once they reach the system's detection range. However, not all these features were demonstrated during this evaluation or other field demonstration testing.
