General rules for the allocation and management of energy measuring instruments in energy consuming units

1 Scope

This standard specifies the basic requirements for the allocation and management of energy measuring instruments in energy consuming units.

This standard is applicable to enterprises, institutions, administrative organs, social organizations and other energy consuming units with independent accounting.

Definitions and terms 3

The following terms and definitions are used in this standard.

three point one

Measuring instrument of energy

The measuring objects are the measuring instruments of primary energy, secondary energy and energy carrying working medium.

three point two

Equipping rate of energy measuring instrument

Percentage of actual installed quantity of energy measuring instruments in theoretical demand

Note: the theoretical demand of energy measuring instruments refers to the number of measuring instruments required to measure the value of all energy.

three point three

Sub organization of energy using

The energy accounting unit subordinate to the energy consuming unit.

4. Allocation of energy measuring instruments

4.1 types and scope of energy measurement

Energy as mentioned in this standard refers to coal, crude oil, natural gas, coke, gas, heat, refined oil, liquefied petroleum gas, biomass energy and other resources that obtain useful energy directly or through processing and conversion.

Energy measurement range:

a) Input the energy and energy carrying working medium of energy consuming units, secondary energy consuming units and energy consuming equipment;

b) Output the energy and energy carrying working medium of energy consuming units, secondary and energy consuming units and energy consuming equipment;

c) Energy and energy carrying medium used (consumed) by energy consuming units, secondary energy consuming units and energy consuming equipment;

d) Energy and energy carrying medium produced by energy consuming units, secondary energy consuming units and energy consuming equipment;

e) Residual energy resources that can be recycled by energy consuming units, secondary energy consuming units and energy consuming equipment.

4.2 allocation principle of energy measuring instruments

4.2.1 it shall meet the requirements of energy classification and measurement.

4.2.2 it shall meet the requirements of energy consuming units to realize energy sub item assessment.

4.2.3 key energy consuming units shall be equipped with necessary portable energy detection instruments to meet the requirements of self inspection.

4.3 allocation requirements of energy measuring instruments

4.3.1 the allocation rate of energy measuring instruments is calculated according to the following formula:

Ns

Rp = —— × 100%

N1

Where:

RP -- allocation rate of energy measuring instruments,%;

NS - actual installed quantity of energy measuring instruments;

N1 - theoretical demand of energy measuring instruments.

4.3.2 energy consuming units shall be equipped with energy measuring instruments.

4.3.3 the secondary energy consumption unit whose energy consumption (capacity or transport energy) is greater than or equal to the limit value of one or more energy consumption in Table 1 is the main secondary energy consumption unit.

Major and secondary energy users shall install energy measuring instruments according to the requirements of Table 3.
