TankMate Versions 3.12, 3.20, 4.1


Certification Leak rate of 0.1 gph with PD = 99.8% and PFA = 0.02% for both single and manifolded tank systems. 
"If a method meets the requirement for detecting a leak rate of 0.1 gph, it will meet the requirement for 0.2 gph.", according to "Standard Test Procedures for Evaluating Leak Detection Methods:  Statistical Inventory Reconciliation Methods", EPA/530/UST-90/007, June 1990, Section 7.2.3, page 30.
Leak Threshold 0.05 gph. 
This leak threshold is for evaluation purposes only.
A tank system should not be declared tight if the test result indicates a loss or gain that equals or exceeds the leak threshold calculated from the data set. This leak threshold may be different than the above leak threshold.
Gains (water ingress) are analyzed and evaluated on an individual basis.
Applicability Gasoline, diesel.
Tank Capacity Maximum of 60,000 gallons for single tank. 
Maximum of 60,000 gallons cumulative capacity for manifolded tank systems with no more than 3 tanks in the system.
Data Requirement Minimum of 15 days of data is required.
System Features Method of data analysis that system employs, and was used during evaluation process, is exclusive of any external control by vendor. 
System consists of a fully automated software package with embedded algorithms for conducting leak detection testing. Consequently, third party evaluation procedure demonstrated that system can be used in-house with no requirement for direct vendor participation.
Evaluation Features Evaluator tested this system for in-house use. 
Computer program disk along with instructional documentation was supplied by vendor to evaluator.
Evaluator, without vendor involvement, analyzed required data and performed evaluation using program disk and accompanying documentation. Vendor was NOT present as an observer during evaluation.
Comments 46% of data sets evaluated were from manifolded tank systems. 
Of 41 data sets submitted for evaluation, all were analyzed with conclusive results. 
Median monthly throughput of tanks evaluated was 53,349 gallons. 
Leak rates of 0.05, 0.10, and 0.20 gph were used in the evaluation. 
Data sets evaluated were supplied by the evaluator.
According to vendor, TankMate Versions 3.12 and 3.20 used the same legacy software language to program those versions and Version 4.1 used current software language to program this version.
