8601 Series and 8601 Series Consoles Monitoring Systems with CSLD

(Continuous Automatic Tank Gauging)


Certification Leak rate of 0.2 gph with PD = 100% and PFA = 0%
Leak Threshold


Threshold PD PFA
Single Tank Systems








Manifolded Tank Systems








A tank system should not be declared tight and a message printed for the operator, if the test results indicate a loss or gain that exceeds this threshold.

Applicability Gasoline, diesel, aviation fuel, fuel oil #4, solvents, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751*. Other liquids with known coefficients of expansion and density may be tested after consultation with the manufacturer. *NWGLDE Listings apply to leak detection functionality only and not material compatibility – see “Disclaimer” on page ii.
Tank Capacity Maximum of 43,722 gallons for single tanks and for up to 3 tanks manifolded together. The minimum product level required to conduct a test is 15% full.
Thrughtput Monthly maximum of 235,000 gallons
Waiting Time Minimum of 3 hours stabilization time is allowed between delivery and data collection
Test Period Data collection time ranges from 25 to 28 days.
Data sampling frequency is once per minute.
System collects data at naturally occurring product levels without interfering with normal tank operation, and discards data from unstable periods when system performs test.
Temperature Average for product is determined by a probe which contains 5 thermistors. At least two thermistors must be submerged in product during test
Water Sensor Must be used to detect water ingress.
Minimum detectable water level in the tank is 0.75 inch.
Minimum detectable change in water level is 0.08 inch.
Calibration Thermistors and probe must be checked and, if necessary, calibrated in accordance with manufacturer's instructions.
Comments System reports a leak rate and a "pass" or "fail" result.
Evaluated using both single and manifolded tank systems with probes in each tank.
For valid monthly testing, a conclusive test report must be produced for each tank every month.
System warns operator if there are no “ passing” tests completed during the month.
