In the past that only top-down energy-saving publicity saving is not enough, must be energy-saving measures to implement the main leaders of the local government and enterprises, and the inclusion of performance, it may bring to the attention. And whether to achieve the target, it is necessary to take a scientific state of the state, through the monitoring of the instrument to assess the effect of energy saving. Therefore, the central government has instructed relevant departments to develop a national standard GB17167-2006, namely "energy use per unit of energy measurement apparatus equipped and management rules" and on January 1, 2007 announced the implementation of. Five of the GB17167-2006 (4.3.2 4.3.3 and 4.3.4 4.3.5. 4.3.8) to mandatory provisions, the core content for: where can reach a certain scale of units and equipment are necessary to install the energy monitoring instrument and of magnitude, monitoring instrument type and the accuracy grade do clearly defined.
In energy monitoring instruments, in addition to the electric energy meter, solid coal with weighing instrument and other gaseous and liquid fuels (such as crude oil, refined oil, heavy oil, residual oil, natural gas, liquefied petroleum gas, gas...... And the carrier energy (water, steam) are required to use the flow meter. Even for solid state energy coal, in the process of continuous operation, also can be used to flush plate type flow meter, or gas and solid two-phase microwave flowmeter. Therefore, the flow meter has the pivotal status in the energy monitoring instrument, which can not be substituted.
The flow meter has many types, in a state of "spring and autumn and the Warring States", but the technology in the rapid development, new instruments such as electromagnetic, ultrasonic and Coriolis, with its simple structure, perfect function, increasingly by users of all ages. Classical style (Kong Ban, jet, Wen Qiu Li) or because of the pressure loss, the requirements of straight pipe section is too difficult to meet the shortcomings of the market development is a downward trend, the annual growth rate of -2.3%. New throttling device also continue to emerge, so new flow meter replace traditional classical instruments will be a long process, not overnight.
