FuelPrime IRC Version 3.2 SIR
Continual Reconciliation System for CITLDS Using Multiple ATG System
with Magnetostrictive Tank Probes for Tanks and Associated Pipelines

(Continual Reconciliation)

Certification Leak rate of 10 liters/24h (0.11 gph) for tanks and associated pipelines with PD > 99% and PFA < 1%.
Leak Threshold 5 liters/24h (0.055 gph) for single and manifolded tank systems including associated pipelines.
A tank system should not be declared tight if the test results indicate a loss or gain that equals or exceeds this threshold.
Applicability Gasoline, diesel.
Other liquids may be tested after consultation with the vendor.
Tank Capacity 62,500 liters (16,511 gallons) for single tanks.
125,000 liters (33,521 gallons) for manifolded tanks. Maximum of 3 tanks manifolded allowed.
Throughput 102,488 liters (27,074 gallons) for single tanks.
195,541 liters ( 51,656 gallons) for manifolded systems.
Waiting Time None.
Test Period Data collection time: 14 days (1,300 – 1,400 readings).
Data sampling frequency: at least four (4) per hour.
System collects data (sales and levels) without interfering with normal site operation.
Temperature Input data must be provided after excluding temperature effect.
Water Sensor Must be used in Automatic Tank Gauge system to detect water ingress.
Calibration The Automatic Tank Gauge used must have thermistors and probe checked and, if necessary, calibrated in accordance with manufacturer's instructions.
Dispenser meter calibrations must be known.
Comments Leak detection method is software based and independent from any specific hardware at site, but appropriate frequency and accuracy of input data is needed.
Automatic Tank Gauges used with this method must employ a magnetostrictive probe and be on the NWGLDE List or be approved by vendor after consultation. Method reports a calculated leak rate and “Pass”, “Fail” or “Inconclusive” for each tank system.
Method was evaluated for tanks and associated pipelines for both single and manifolded tank systems with probes in each tank.
Calibration errors, dispensing meter errors, vapor loss, thermal effects, conversion chart miscalibration must be known.
The maximum size tank system in the evaluation was 100 000 liters (~26 417 gallons).
The 80th percentile of tank sizes was 25,000 L (6,604 gallons).
The maximum throughput in the evaluation was 156,433 liters/month (41,325 gal/mo).
The 80th percentile of throughputs was 17,325 L/mo (4,431 gal/mo).
