INTRODUCTION
This pattern of an electrically driven flow meter comprises of a dispensing unit operating in
attended or unattended mode. It is manufactured by Larsen & Toubro and is designated as
SPRINT Pump. This pattern is suitable for liquids other than water of low viscosity
(<5mPa.s) including fuel blended with ethanol / biodiesel or biodiesel but excluding liquefied
gases. Each dispensing unit is available as a mono, dual or multi product pumps with two to
ten nozzles. They may have an oil mix facility with a fixed or variable percentage option.
Each pumping unit is independent and can dispense a different grade of fuel, it may have a
single or double sided display for displaying the price per litre, the volume dispensed and the
sale amount. The transaction data for each meter is shown on an electronic display. The
dispenser has indication of 7/6 digits for amount, 7/6 digits for volume and 6/4 digits for the
price per litre. The LCD display size can vary depending upon customer requirements. The
smallest division is 1 ml. The pumps are provided with Presetting or Non-Presetting facility.

2.2
Hydraulics (Figure 7)
The hydraulic unit is a suction system comprising of a motor driven pumping unit, with
integral air separator, feeding a four-chamber positive displacement meter, with associated
non-return and pressure relief valves. For a pressure system, the inlet pipe is directly
connected to the positive displacement meter therefore a motor driven pumping unit is not
required. The meter output pipes are routed to the hose supports. Depending upon the number
of fuels to be dispensed and the number of fuelling positions, there can be up to five such
independent hydraulic arrangements per dispenser.
2.2.1
Combined pump and air eliminator
The pumping unit is manufactured by Larsen & Toubro (Figure 8). It is belt driven from an
electric motor. The pumping unit is of rotary type with sliding carbon blades housed into the
rotor. The body is made of aluminium alloy. It has a filter/strainer assembly with a
unidirectional check valve at its inlet. The pressurised fuel is passed through an inbuilt air
separator zone. The fluid is then passed through another filter to the metering unit. It has an
inbuilt float chamber where collected fuel vapour is allowed to condense. It has a float
actuated needle valve to circulate the pure fuel back into the suction side. When the delivery
is stopped the unit is provided with an adjustable bypass valve which diverts the liquid flow
into the suction side of the pump. The liquid from the unit then passes into the metering unit
via a pressure regulating valve.
The pressure relief valve in the liquid line relieves any excess pressure generated on the
nozzle side to prevent the hose collapsing under pressure. It also prevents the hose from
bursting, for example, due to temperature increases of the liquid in the hose. The regulating
valve comes back to its original position when the delivery is stopped. This ensures presence
of fuel always from the point of measurement.
2.2.2
Positive displacement meter (Figure 9).
The meter is manufactured by the Larsen & Toubro L&T. The 4 Piston Metering Unit is
essentially a volumetric measuring device precision built for sustained accuracy.
The metering unit has a metal die cast body that houses 4-burnished liners in 4 cylinders
fitted with PTFE Piston Cups. The metering unit comprises of a single sealing face,
comprising of a valve seat and a kidney valve. The kidney valve has 2 ports positioned at
180° to each other, one for inlet and one for outlet of the fluid. The valve seat has 4 ports at
90° to one another. The ports are in turn connected to the above measuring chambers. The
positive drive is provided by the flow of the fluid, which generates the movement of the
connecting bars screwed to piston assemblies. The linear motion of the connecting bar is
transformed into rotary motion by a crank-rod assembly. The crank-rod assembly comprises a
crank-rod and rollers. A pin on the rod drives the valve on the valve seat. The rotary
movement of the crank-rod is transferred to an electronic register which is directly mounted
on the meter. The 90° disposition between measuring chambers and 180° between inlet and
outlet ports of valve prohibits static conditions within the meter.
Calibration of the meter is carried out mechanically by adjusting the calibration wheel on the
cover of the meter. In case of electronic calibration it is done via the calibration card. The
4
value of output in ml per pulse is adjusted to get the measured quantity within permissible
limits.
2.2.3
Pipe work
The pipe from each meter is routed to fixing points on the enclosure to which the flexible
hose is attached, with the hose terminating in a nozzle. Nozzles are stowed in holsters either
on the sides or on the front of the hydraulics enclosure. Solenoid valves are provided in the
line for preset pumps.

circuitry is on the computing display board. It may have the extra facility to show additional
fuel parameters such as density.
The software version number version number is 02.xx.yy, where 02 is the legally relevant
part of the software, the xx is for major changes to the software, and yy is for minor changes,
both of which do not affect the legally relevant parts of the software.

The volume display XXXXX.XX or XXXX.XX is of the 7-segment liquid crystal type.
Providing mains power is present, lifting the nozzle will cause the display to show all “8”s,
all “blanks” then all “zeros”. To reset the display, the nozzle should be kept in the boot for
approximately one second, before lifting the nozzle.

sealing wire through hole in the sealing screw used for mounting the sensor box onto the
meter, and then into a seal.

2.6.2
Meter (Figure 16)
The meter is sealed by a sealing wire being passed through two screws on each cylinder head,
calibration wheel, calibration locking pin, and then into a seal. For meters with electronic
calibration facility, the sealing is done is a similar way minus calibration wheel and locking
pin.
2.6.3
Calibration
The calibration adjustment wheel is sealed by a sealing wire being passed through the
calibration locking pin, around the calibration wheel shaft and then into a seal (Figure 17).
For electronics with the electronic calibration facility on the pulse transmitter card, the cover
of the sensor box is also sealed, to prevent its removal, by passing sealing wire through hole
in sealing screw, placed diagonally opposite, and then into a seal (Figure 18).

OPERATION
3.1
Operating sequence
At the start of the transaction, the dispenser displays the previous sale. The operator removes
the nozzle corresponding to the grade required at the appropriate end of the dispenser. The
corresponding display(s) show all “8”s, all “blanks” then all “zeros”. Then the appropriate
motor is started permitting a delivery to commence. At the end of the delivery the nozzle is
replaced in the nozzle holster/boot and the pump motor stops.

AUTHORISED ALTERNATIVES
4.1
Having the dispensing unit described in the certificate as a single unit with one
pump/meter/hose or a multi product unit with a dedicated pump(s)/meter(s)/hose(s). These
individual units will act as a single dispensing unit in a common enclosure.
4.2
Having the dispenser connected to a Timeplan Fuel Management System
(Sigma) as described in GB Test Certificate GB-1322. The Timeplan Management System
(Sigma) may either be in a separate enclosure near the dispenser or may be included in the
same enclosure as the dispenser.
