Notes:

  • 1.  Damaged probes must be cleaned or replaced as appropriate. Probes used in heavier products such as waste oil should be checked more frequently. Heavier products can leave deposits on the probe shaft and float assemblies that may restrict the measurement capacity of the probe.
     

  • 2.  Because the magnetostrictive probe consists of moving parts, its sensors can be damaged by excessive frictional wear as well as residue build-up. Residue build-up can affect the weight of the sensor as well as inhibit its ability to slide freely along the guide tube. Inaccuracies in the product level measurements could indicate a problem with the probe sensors. For additional testing of the probe sensors, perform the following test:
     

    • Remove the probe from the tank and place it carefully on the ground.

    • Place the water sensor flush with the bottom of the probe shaft and place the product float near the middle of the probe shaft. 

    • Check the height reading on the tank gauge monitor (after allowing sufficient time for the monitor to respond). Measure the distance from the bottom of the probe to the bottom of the product float and compare it with the reading on the monitor.
       

  • 3.  To test the accuracy of the product sensor: 

    • Using the tank console monitor, take an initial fuel level reading.

    • Dispense one gallon of product into a calibrated container.

    • Using the tank console monitor, take a second fuel level reading. 

    • Verify that the change in tank volume is one gallon.
       

  • 4.  To test the accuracy of the water sensor: 

    • Remove probe from the tank.

    • By hand, move the water float up the probe to a point higher than the high-water alarm set point.

    • The monitor should respond with a high water alarm report. (The water height may also appear on the tank monitor display console.

    • Check this height against its actual location. The high water level alarm should not be set so high that water ingress into the tank goes undetected for long periods of time.

This checklist is not intended to tell the technician how to perform the maintenance and system check.  Technicians should follow manufacturers' detailed instructions while making sure that all of the items on the checklist have been covered.

Yes

No

Are all alarms activated and functioning properly?

Yes

No

Comments:

 

 

Notes:

  • 1.  Damaged probes must be cleaned or replaced, as appropriate. The mass displacement probe is very susceptible to dirt and residue build-up and should be checked semi-annually and cleaned, if necessary. Mass displacement probes used in viscous products such as waste oil should be checked more frequently. Products of this type can leave heavy deposits on the probe which may inhibit the accuracy of the probe. Checking a reconciliation report and/or manual sticking could verify the system's accuracy.
      

  • 2.  To test the accuracy of the product sensor:

    • Using the tank console monitor, take an initial fuel level reading.

    • Dispense one gallon of product into a calibrated container.

    • Using the tank console monitor, take a second fuel level reading. 

    • Verify that the change in tank volume is one gallon.
       

  • 3.  To test the accuracy of the water sensor: (Note: water sensor is separator from the mass buoyancy probe.)

    • Remove the probe from the tank. 

    • By hand, move the water float up the probe to a point higher than the high water limit.

    • The monitor should respond with a high water alarm. (The water height may also appear on the tank monitor display console.)

    • Check this height against its actual location.
       

  • 4.  The high water level alarm should not be set so high that water ingress into the tank goes undetected for long periods of time.

LLDs Maintenance Checklist

Minimum procedures to be conducted by a qualified service technician

Yes

No

NA

For equipment start-up or annual equipment certification, was a leak simulated to verify LLD performance?

(Circle all that apply) Simulated leak rate: 3 gph 0.2 gph 0.1 gph

Yes

No

NA

Is the audible alarm operational?

Yes

No

NA

Is the visible alarm operational?

Yes

No

NA

If alarms are relayed to remote monitoring system, is all communication equipment (e.g. modem) operational?

Yes

No

NA

Was monitoring system set-up reviewed to ensure proper settings?

Yes

No

NA

Was the testing apparatus properly calibrated?

Yes

No

NA

For mechanical LLDs, does the LLD restrict product flow if it detects a leak?

Yes

No

NA

For electronic LLDs, have all accessible wiring connections been visually inspected?

Yes

No

NA

For electronic LLDs, does the turbine shut off if the LLD detects a leak?

Yes

No

NA

For electronic LLDs, does the turbine shut off if any portion of the monitoring system is disabled or disconnected?

Yes

No

NA

For electronic LLDs, does the turbine shut off if any portion of the monitoring system malfunctions or fails a self-test?

Yes

No

NA

Were all items on the equipment manufacturer’s maintenance checklist completed?

No

NA

Were all LLDs confirmed operational and accurate within regulatory requirements?

Comments:

Notes:

  • Line leak detectors should be tested in-place, not removed.
     

  • The functional elements of the mechanical LLD are the piston and the diaphragm. To ensure that these elements are functioning properly, the submersible pump can be started and the time that the piston or diaphragm takes to move into a position to enable full flow of the product noted. The range of allowable opening times is specified by the manufacturer and is available in the equipment manual.
     

  • Equipment that monitors underground storage tank systems containing hazardous materials must be tested/serviced per regulatory requirements, or on a schedule specified by the manufacturer, whichever is more frequent.
     

  • System Set-Up Report - If the monitoring system or diagnostic equipment used in testing is capable of generating a hard-copy report describing system set-up, you should include a copy of the report with this checklist.
     

  • Alarm History Report - If the monitoring system is capable of generating a hard-copy alarm history report, you must include a copy of the report with this checklist. This report should be printed before you test any LLDs.
