The Measuring Instruments (Liquid Fuel and Lubricants) Regulations 2006

Definitions

2.—(1) In this Schedule—

“associated measuring instrument” means measuring equipment connected to the calculator for measuring certain quantities which are characteristic of the liquid fuel, with a view to make a correction and/or conversion;

“base conditions” means the specified conditions to which the measured quantity of liquid fuel at metering conditions is converted;

“calculator” means a part of a meter that receives the output signals from the measurement transducer(s) and possibly from associated measuring instruments and displays the measurement results;

“climatic environments” means the conditions in which measuring systems may be used;

“conversion device” means a part of the calculator which by taking account of the characteristics of the liquid fuel (e.g. temperature, density) measured using associated measuring instruments, or stored in a memory, automatically converts—

(a)

the volume of the liquid fuel measured at metering conditions into a volume at base conditions and/or into mass;

(b)

the mass of the liquid fuel measured at metering conditions into a volume at metering conditions and/or into a volume at base conditions,

and includes the relevant associated measuring instruments;

“critical change value” means the value at which the change in the measurement result is considered undesirable;

“direct indication” means the indication, either volume or mass, corresponding to the measure and that the meter is physically capable of measuring;

“direct sale” means a trading transaction if—

(a)

the measurement result serves as the basis for the price to pay;

(b)

at least one of the parties involved in the transaction related to measurement is a consumer or any other party requiring a similar level of protection; and

(c)

all the parties in the transaction accept the measurement result at that time and place;

“disturbance” means an influence quantity having a value within the limits specified in the appropriate requirement but outside the specified rated operating conditions of the instrument. An influence quantity is a disturbance if for that influence quantity the rated operating conditions are not specified;

“fuel dispenser” means a measuring system intended for the refuelling of motor vehicles, small boats and small aircraft;

“influence quantity” means a quantity that is not the measurand but that affects the result of measurement;

“interruptible” means the liquid fuel flow can be stopped easily and rapidly;

“measurand” means the particular quantity subject to measurement;

“Q_max” means the maximum flowrate;

“Q_min” means the minimum flowrate;

“rated operating conditions” means the values for the measurand and influence quantities making up the normal working conditions of an instrument;

“self-service arrangement” means an arrangement that allows the customer to use a measuring system for the purpose of obtaining liquid fuel for his own use; and

“self-service device” means a specific device that is part of a self-service arrangement and which allows one or more measuring systems to perform in this self-service arrangement.

(2) In this Schedule, volume may be read as mass and “L” may be read as kg.
