Whitby Tanks FAQ
What is a Mild Steel Tank System?
A tank system consists of a primary container with an integral secondary containment.
The inner tank provides the required storage area, whilst the outer tank forms a watertight bund with capacity for 110% of the total liquid stored.
The inner tank is manufactured generally to BS799 Part 5 and the tanks are manufactured in new primed steel of a thickness of steel sheet to suit the capacity required. Certification of the steel is available upon request.
The tanks are manufactured with a venting system which allows any overfilling that may occur to flow straight into the bund cavity, which in turn can be fitted with either a gauge, or alarm, which would detect any overfilling or leakage.
The tanks have top outlets only, which can be used for filling, suction drains, gauges and pumps. No tanks are made with any outlets through the bund wall unless specifically requested by our clients.
Our tanks comply with all current known legislation (DETR, Environment Agency, DEFRA).
What is a Bunded Tank?
A Bunded Tank (preferred generic term: Proprietary Tank System or Tank System) consists of a primary container with an integral secondary containment.The inner tank provides the required storage area, whilst the outer tank forms a watertight bund with capacity for 110% of the total liquid stored.
What is a fuelling station?
A fuelling station provides containment for the anciliary equipment associated with the tank.
How Do I Choose A Pump?
How Many Litres Per Minute Do I Need?
Typical forecourt pump dispenses at 35L/min (Litres per minute)
Pumping speeds of 35 to 50L/min are ideal for refuelling cars, vans, forklifts and small plant equipment.
Pumping speed of 70L/min is ideal for refuelling large vans and small trucks.
Pumping speed of 90L/min is ideal for refuelling large trucks, buses, coaches, and large plant equipment.
How Accurately Do I Want To Measure My Fuel?
Pumps with +/- 0.5% accuracy are similar to those of forecourt pumps. If you fill a vehicle with fuel this type of pump shows 100 litres on the display, it means you actually dispensed between 99.5 and 100.5 litres, leaving an uncertainty of 4 litres or 4 times worse than the +/- 0.5% type of pump
Pumps with +/- 2% accuracy are less expensive but less accurate. If you fill a vehicle with fuel until this type of pump shows 100 litres on the display, it means you actually dispensed anything between 98 and 102 litres, leaving an uncertainty of 4 litres.
These errors may not seem much, but if you apply this to your overall fuel bill the difference becomes substantial. For example, if you dispense 10,000 litres per month from a pump having an accuracy of +/-2%, then you have actually used between 9,800 and 10,200. This is uncertainty of 400 litres per month, at say 80 pence per litre, would equate to £320.
Where Is My Fuel Storage Tank?
If your tank is below ground you need a pump with a much better suction capability. If your tank is above ground less suction lift is required. Your pump will only work correctly if properly installed.
How To Set Up An Ocio Gauge
When the power is switched on, a serial number will appear, you will need to remember the last two digits to gain access to the OCIO system.
Hold down the ENT button, and press CANC button then let go.
The OCIO will ask for a pin number, enter the last two digits of the serial number. (this can be done by using the scroll buttons on the front face)
The OCIO will display unit? This is factory set as litres / millimetres. To change this to gallons /inches scroll up/down, and press enter when you reach your desired measurement.
The OCIO will now read TANK? If you press ENT, you will be asked TANK SHAPE A you will need to put in the tank shape by scrolling through the menu.
A = Cylindrical vertical tank
B = Cylindrical horizontal tank
C = Rectangular tank
NONE = This will only show the contents in height i.e. Millimetres / Inches
A rectangular tank measuring 2500mm High x 2500mm Wide x 6000mm Long
When in TANK? Choose shape 'C'.
The OCIO will read TANK SHAPE C HEIGHT 0000. Scroll up/down to reach the number '2' and press ENT, this will proceed to the next digit, again Scroll up/down to reach the number '5'
then press ENT, the next two digits will be '0' so press ENT twice. The height is now set to 2500mm.
The screen will change to TANK SHAPE C WIDTH 00000. The first digit is a '0' so press ENT, scroll up/down to reach the number '2' press ENT, this will proceed to the next digit, again Scroll up/down to reach the number '5' then press ENT, the next two digits will be '0'
so press ENT twice. The width is now set to 2500mm.
The screen will now change to TANK SHAPE C DEPTH 00000. The first digit is a '0' so press ENT, scroll up/down to reach the number '6' press ENT, this will proceed to the next digit, again scroll up/down to reach the number '0' then press ENT, the next two digits will be '0'so press ENT twice. The width is now set to 6000mm.
NB:- The maximum height of the tank cannot exceed 4000mm.
When entering the sizes of the tank please note that the height has 4 digits, but the width and depth will have 5 digits
