Descriptive Annex

1 INTRODUCTION

This pattern of an electrically driven meter comprises a dispensing unit operating in attended

stand-alone mode. It was originally manufactured by Schlumberger RPS Dunclare and

designated the Elite. It is now manufactured by Tokheim with several designations as listed in

this descriptive annex. The transaction data for each side is shown on the display and

computing head. The dispenser can indicate up to 999.99 litres giving an indication every 0.01

litres. The price-to-pay indication indicates up to £999.99 in intervals of £0.01. The unit price

increments every 0.1 pence per litre up to a maximum of 999.9 pence per litre.

The dispenser is of a modular design, with the master module comprising the electronics and

display head supported by a column as well as a hydraulic unit and hose retractor assembly.

The hydraulic unit is manufactured by Tatsuno and comprises a motor driven pumping unit

with integral air separator feeding two meters. The slave module comprises a hydraulic unit

and hose retractor assembly.

There may be up to four slave modules supported by the master module. This allows up to five

nozzles on each side of the dispensing unit. Electrical interlocks permit the use of only one

nozzle on a particular side of the dispenser at any one time. Any single nozzle may be used on

the opposite side of the dispenser at the same time.

This pattern is suitable for liquids other than water of low viscosity (<20mPa.s) except

liquefied gases. This includes ethanol blends up to 100% ethanol.

2 CONSTRUCTION

2.1 Mechanical (Figure 1)

The dispensing units are assembled using two types of hydraulics housings. These are a master module

and slave module, both of which contain the same hydraulic units, cabling and hose retraction

assemblies. In addition, the master module has a short column upon which is situated the

electronic calculator and display. Structural assemblies and paneiwork are constructed in steel.

Approximate Dimensions:-

Master module:

1565 mm high

510 mm wide

470 mm long

Slave module:

1,140 mm high

510 mm wide

470 mm long

2.2 Hydraulics (Figure 2)

The hydraulic unit comprises a motor driven pumping unit feeding two meters, and associated

air separators, non-return and pressure relief valves. The meter output pipes are routed via

solenoid valves to the hose retraction assemblies. There can be up to five such hydraulic

arrangements per dispensing unit.
