Research On Potable Heat Meter Examine Apparatus

At present puts in the market the calorimeter regardless of in the precision, either the stability or the quality aspect all cannot satisfy the calorimeter examination installment the request .In view of this insufficiency, this article has designed one kind take the ultrasonic wave flow measurement as the principle portable calorimeter instrumentation, lets it realize the high accuracy survey, examines the household with the calorimeter precision whether does answer the purpose. Like this not only satisfies the heating system the request, but also can cause the user even more to feel relieved accepts the calorimeter, raises their energy conservation consciousness.The portable calorimeter instrumentation takes the 80C196KB monolithic integrate circuit as a core, selects the corresponding ultrasonic wave type flow sensor and the temperature sensor realization to the current capacity, the temperature examination and the survey, may demonstrate the correlation parameter, causes it with the household the parameter contrast which obtains with the calorimeter, thus realization examination function. At the same time, proposed one new k coefficient compensating process has realized the heat number on-line temperature and pressure compensation, large scale increased the thermal measurement precision. Breaks the tradition when the ultrasonic wave flow measurement aspect in the method of difference ultrasonic wave in coefficient and so on in fluid refraction angle, sound track length can along with the fluid working condition the change changes the shortcoming, we use improvement the time difference algorithm, thus greatly increased the flow measurement precision. In the mechanism, uses outside which supersonic poked head in to clamp the type to install the way, enabled the ultrasonic transducer in the situation which did not block the flow to be allowed to facilitate replaces also is advantageous for carries, to realize portable.
