Dynamic performance – a very important criterion when using flow meters in the circuits of automatic control and management of rapidly changing costs. From Performance measurement systems, of which may include flow sensors, depends largely on the quality of the final product, as well as savings or overruns of raw materials and energy and a variety of 5.Bolshie Measuring range – extremely important that the meter provides stable readings and record the entire range of energy consumption. The less he will have a so-called “dead zone”, the better will be his testimony. This is especially true for companies engaged in the sale of energy and coolant to other organizations. 6.Obespechennost metrological base – when choosing a meter or a meter, be taken into account in factory repair facilities, as well as verification systems for periodic maintenance and inspection of metrological characteristics used in flow sensors and meters the amount of substance. 7.Izmerenie flow in extreme conditions – selected instruments must provide not only high accuracy but also the explosive fire protection, when measuring the cost of flammable liquids and gases, in the broadest ambient temperatures.
If we choose the maximum value of the proposed criteria, such flowmeters and meters will cost for the company is very expensive and may result from savings on payments Energy does not pay for such costly investments, and for the population, such devices will be generally available. For the design organizations offering selection of such equipment, it is important to strike a balance between the required metrological characteristics of instruments and their value, taking into account the technological characteristics of the object on which they are used. For the population of all a little bit easier: in homes do not have extreme measurement conditions, no explosion and fire agents, the cost of energy consumed by several orders of magnitude lower than in industry. Yes, and staff in organizations serving the residential houses, not sufficient expertise and verification equipment that would work with expensive metering and counters. Therefore not even worth watching in the direction of expensive measurement systems meet all of the above requirements. Come to the fore the price of the flowmeter and its reliability. And it is quite sufficient to install an inexpensive turbine blade or counter, what would the cost of its maintenance, are commensurate with the savings to pay used for energy.
