a.) Sight: This can be a sight tube that runs to the top of the tank (small tanks normally), or cat and mouse gauges.
b.) Mechanically Pneumatic: Pneumatic reading gauges (hydrostatic), where fuel is displaced from a tube and the resultant back pressure formed by the head of oil gives a reading on a gauge.
c.) Electronically: This can be various systems, as above, giving either analogue or digital readings

Question: What is Fuel Management?

Answer:
Fuel management is where the above, plus some form of registering what fuel is taken from the storage vessel, normally through a flow meter.

Question: Is a single skin or a Bunded Tank required?

In all cases a risk assessment should be carried out by a suitable qualified engineer.

If the following apply then a bunded oil tank is to be installed:

  • Tank capacity in excess of 2500 litres
  • Tank within 10m of controlled water
  • Tank located where a spillage could run into an open drain or to a loose fitting manhole cover
  • Tank within 50m of a borehole or spring
  • Tank over hard ground or hard-surfaced ground that could enable spillage run-off to reach controlled water
  • Tank located in a position where the vent pipe outlet is not visible from the fill point
  • Tank supplying heating oil to building other than a single-family dwelling

Question: What is a Bunded Oil Tank?

A bunded oil tank is a double walled tank or a tank within a tank. The inner tank stores the oil and the outer tank acts as a bund which encases the inner tank. The outer tank holds 110% of the capacity of the inner tank. If there is a spill or leak from the inner tank it’s captured in the outer tank so avoiding groundwater pollution.


Question: What is an Integrally Bunded Oil Tank?

An integrally bunded tank is an outer tank which is normally attached to the inner tank to rely on the inner tanks build characteristics for additional design support and strength.


Question: What is a Double Skinned Tank?
 
Answer:
A double skinned tank is a type of tank manufactured by some companies. This is where the outer tank is laid directly on the inner tank (two skins). To obtain structural strength on the outer tank a method is to support it externally or to drill holes in the outer plate and fillet weld the inner to the outer plate filling the hole in again. Some tanks manufactured like this have no secondary containment of 110%, unless additional space has been added to the outer skin to allow for this.

 


 

Question: What type of base is required for the Tank?

Answer:

The tank must be completely supported on a non-combustible base and the base must extend 300mm around the footprint of the tank.


Question: How often should the Filter be changed?

Answe:

The filter requires changing every 6 months, or if the flow rate reduces.


Query: Reasons for the Pump NOT running.


Answer: Thermal overload may have tripped, this can be reset, it is located on the pump control box (fig 1). Push the button once, and then try the pump again

Fig 1 - Pump not running Fig 1

Answer: Check the electrical connections are tight. 


Query: Pump is running, but still can NOT dispense fuel - Why?

Answer:

Potential air lock from first fill and subsequent fills, or the pump has been run dry.
Resolution: Whilst the pump is running, slightly undo the filter to release any air or slightly undo the connection at the nozzle


Query: Pump runs, but there is a reduced flow rate. Why?

Answer:

A blockage or restriction in the system may have caused a reduction in the flow rate.
Resolution: Inspect the filter element for a blockage, and replace if necessary.


Query: Flowmeter out of calibration. How can this be rectified?

Diesel Flowmeter

Answer:                

  1. Wait for the flowmeter to be on standby (no figures displayed) then press the reset button to reset the total.
  2. Dispense a quantity of liquid into a pre measured container, and note the exact measurement in the container.
  3. If the flowmeter is out of calibration it should have a different total to that dispensed in to the container.
  4. Hold the menu button until the figure on the left begins to flash.
  5. Press the reset button to alter the flashing figure between 0 -9.
  6. Press the menu button to move the flashing pointer along one.
  7. Repeat this process until the figure on the screen reads the same as what was recorded by the measuring device.
  8. When correct, hold the menu button.
  9. The flowmeter is now re-calibrated.

Query: Watchman gauge reading incorrectly or showing no reading. How can this be rectified?

Answer:

  1. If the Watchman gauge reads incorrect compared to the amount of liquid in the tank it must be recalibrated. To do this, take the Watchman from the tank to the plug-in receiver (must be plugged in) and re-pair the devices. This is done by holding the white dot on the Watchman to the black dot on the receiver for 20 seconds. This pairs the device again and should now work as previous. If still reading incorrectly please refer to office for further assistance.
    Ref to Fig. 2. below.
    Watchman Sonic
  2. If the Watchman gauge has no reading, the batteries in the sonic reading device need replacing.
