Requirements for meters



1.1 Meters are devices, which, depending on the characteristics of the

the vehicle in which they are installed, and the rates in them

have been set up, automatically calculated and displayed on an ongoing basis, if they are

in operation, the amount that the customer has a vehicle marked taxi

pay based on the distance travelled and at a speed lower than the

threshold, based on elapsed time of the car rental duration, excluding

various supplements, which may result from legislation in force in

the Member States.

1.2 Special terms

Data display meter depend upon redemption of any rates on

the constant "k" of the taximeter and the constant "w" of the vehicle, in which the

the meter is installed. This constant "w" is a function of the effective circumference "u"

the wheels of the vehicle and the ratio of the number of revolutions of the wheels to the number of revolutions of the part of the vehicle

used to link a metered taxi vehicles.

1.2.1. Constant "k" of the taximeter

The constant "k" of the taximeter is characterized by a quantity that indicates the type of

and the number of pulses that the instrument must accept in order to provide

the correct value data corresponding to a given distance travelled.

This constant "k" is expressed:

and as the number of rotations) per one kilometre

(Rev/km), or

(b)) as the number of pulses per one kilometre


Depending on whether the information relating to the distance travelled

the vehicle is fed into the taximeter as its main shaft speed

(the drive shaft in the entry point into the device), or in the form

electrical impulses.

1.2.2 Constant vehicle "w"

The "w" of the vehicle constant is a quantity indicating the type and number of pulses

intended for the propulsion of the taximeter and that show in the appropriate device,

which is the vehicle for this purpose, and the corresponding distance


This constant "w" is expressed:

and as the number of rotations) per one kilometre

(Rev/km), or

(b)) as the number of pulses per one kilometre


Depending on whether the information about the distance travelled by the vehicle is given by

the number of revolutions of the part driving the taximeter or whether it is given by the number of

electrical impulses.

This constant change depending on several factors, in particular

in air pressure and wear and tear on the payload of the vehicle

and on the conditions under which the ride is in progress. This constant must be determined

under normal test conditions for the vehicle (1.2.7).

1.2.3. Effective circumference "u" of the wheels

Effective circumference "u" of the wheels of the vehicle, which drives the taximeter directly or

indirectly, the distance travelled by the vehicle during one of the total rotation

This round. If the meter is powered by two wheels together, is effective

circuit, expressed in millimetres of the effective diameter of the two circuits


Effective circumference "u" is in a relationship with a constant "w" of the vehicle (point 1.2.2) and the

This circuit must, if it is necessary to specify, provide for

the conditions referred to in point 1.2.7.

1.2.4. the adjustment device

The purpose of the adjustment device is to modify the constant "w" of the vehicle on the

the constant "k" of the taximeter.

1.2.5. Range of permissible errors

Range of permissible errors mentioned in item 5 only depends on the device

itself (errors). The actual value (point 5) used for

determination of errors are calculated from the constant "k" of the taximeter and rates

were in the taxi meter set.

Range of permissible errors determines the maximum deviation between the largest and

the smallest indications.

1.2.6. Changeover speed

Changeover speed is the speed at which the drive of the indicating device

the taximeter changes of mode of calculation by counting elapsed time mode

the calculation by counting the distance travelled, and vice versa.

This speed is obtained by dividing the "time" rates the rate of "distance".

1.2.7. Normal test conditions for the vehicle (for determining its


"Normal test conditions for the vehicle" are obtained, if:

a) tyres fitted to the wheel or wheels driving the taximeter are

of a type which has the same effective circumference "u", such as the wheels,

that are used for determination of the constants of the "w".

(b)) these tires must be in good condition and must be inflated to the

the correct pressure;

(c)), the load carried by the vehicle is approximately 150 kg. (According To the

the Convention corresponds to the weight of two adult persons, one of them is


(d)) the vehicle is moving under its own power in a straight line after

a level surface, at a speed (40 +/-5) km/h.

If these tests are carried out under different conditions, e.g.. with different

weights, different speeds or speed step, on the test

stand, etc., then the results are adjusted by the conversion factor

necessary to convert these values to the values that would provide for the

the above "normal test conditions".



For information provided or displayed by taximeters are allowed only

the following units of measurement:

-metre or kilometre, for distance.

-Second, minute, or hour, for the last time.

The fare must be expressed in legal units.



3.1 measuring devices and calculated device

3.1.1. The taximeter must be constructed in such a way that it calculates and

show the amount of the fare solely on the basis of:

the vehicle moving at a speed greater than the changeover speed;

(b)) time (elapsed time-driven drive) when the vehicle is moving

at a rate less than the changeover speed or has stopped.

3.1.2 the distance-based Drive must be effected by distance wheels, reversing

vehicles, however, must not cause a reduction in the value of the fare, or shown

the distance travelled.

Drive past the time driven must be effected by time, which may

be activated only a control device of the taximeter.

If the mechanical timekeeping manually wound, then it must work

at least eight hours without stretching or two hours if there is a

cocking system associated with each manual activities that precedes the

start of the taximeter.

If the mechanical timekeeping electrically wound, then it must be

indicator, if any;

(b)) to the operating position "FARE", which shows the final amount

to pay, without any extra charge. In this position, the actuator must be

elapsed time-driven and drive the distance-the distance

plugged in at a rate that is allowed in each Member State by the competent

Regulation of rates.

3.2.4. The function of the control device

The functionality of the device is subject to the following restrictions:

starting from any) operating position at any rate must not be

possible to return the taximeter to the operating position "for hire", without passing

through the "stopped" position. The transition from one tariff to another must, however,

still be possible;

(b)), starting from the "stopped" position must not be possible to return

the taximeter to the operating position at any tariff without passing through the

"for hire" position;

(c)) the taximeter must be so designed that changing from one tariff to another by

indicating the fare.

3.4. Optional supplementary devices

A taximeter may in addition be equipped with additional devices, such as

for example:

and) recording devices to the vehicle owner;

(b)) equipment for printing tickets or strip indicating the amount of the fare to

the payment.
