Hectronic GmbH

Hectronic Optilevel Dynamic Leak Detection System, Optilevel CITLDS
(Capacitance Probe)

CONTINUOUS IN-TANK LEAK DETECTION METHOD (CONTINUOUS AUTOMATIC TANK GAUGING)
Certification Leak rate of 0.2 gph with PD = 95.0% and PFA = 5.0% for single tank systems.
Leak rate of 0.2 gph with PD = 95.0% and PFA = 5.0% for manifolded tank systems.
Leak Threshold 0.1 gph.
A tank system should not be declared tight if the test result indicates a loss or gain that equals or exceeds this threshold.
Applicability Gasoline, diesel, aviation fuel, fuel oil #4.
Other liquids may be tested after consultation with the manufacturer.
Tank Capacity Maximum of 11,869 gallons for single tank systems.
Maximum of 23,778 gallons for manifolded tank systems.
Minimum product level required is 14% of the tank diameter.
Throughput Monthly Maximum of 126,923 gallons. Applies to single and manifolded tank systems.
Waiting Time Minimum of 2 hours stabilization time is allowed between delivery and data collection.
Test Period Average is 5.95 days.
Data sampling frequency depends on tank activity.
Temperature Average for product is determined by a temperature-averaging probe.
Temperature is measured by a resistance temperature detector (RTD).
The RTD is mounted in a metal pipe that runs the length* of the probe allowing for temperature averaging.
(*starts about 1 inch above the tip of the probe)
Water Sensor Must be used to detect water ingress.
Minimum detectable water level in the tank is 1.298 inch.
Minimum detectable change in water level is 0.046 inch.
Calibration The probe features 10 measurement segments (10 capacitance segments) and uses a comparison method (self calibration process) which allows the sensor to run without any external calibration.
Comments System consists of a capacitance probe, a micro processing unit inside the head of the probe, and a separate control panel to record and display test data.
Probe was not tested with oxygenated fuels. However, manufacturer states that probe will work with these types of blended products.
Tests only portion of tank containing product.
