Heat charge recorder

Abstract

The present invention discloses a heat charge recorder. The recorder comprises a Bitobar flow meter for measuring fluid flow in a pipeline, an inlet temperature sensor for measuring temperature at the fluid inlet end of the pipeline, an outlet temperature sensor for measuring temperature at the fluid outlet end of the pipeline, and a heat integrating instrument. Signal output ends of the inlet temperature sensor and the outlet temperature sensor are connected with a signal input end of the heat integrating instrument, and the Bitobar flow meter is provided with a flow integrating instrument which has a flow signal output end being also connected with the signal input end of the heat integrating instrument. The recorder provided by the invention is simple in structure, easy to install and low in procurement cost. The Bitobar flow meter provided by the invention has high measurement accuracy which generally achieves level 1.0, and is very suitable for measurement of heat of domestic consumers; and the Bitobar flow meter is applicable to variety of fluid mediums, thereby the heat charge recorder provided by the invention has the advantages of block resistance and corrosion protection, and service life thereof cannot be influenced by measured mediums in the pipeline.

Description

technical field [0001] The invention relates to a heat meter for heating, in particular to a heat charge recorder suitable for household heating. Background technique [0002] Heating is needed in northern my country in winter. In order to save energy and reduce smoke and dust, most areas have centralized heating through heating networks. Heat energy is sold as a commodity and needs to be charged. At present, the common practice is to charge heating fees based on the building area. This method of charging heating fees is obviously unreasonable and should be calculated according to the actual heat energy used by users. At present, there are not no instruments for automatically accumulating heat, such as mechanical, electromagnetic, ultrasonic and other types of heat meters, but because of the high price and low accuracy of these heat meters (the general measurement accuracy is only about 2%) And because the problem of the measured medium in the pipeline affects the s...

Problems solved by technology

At present, there are not no instruments for automatically accumulating heat, such as mechanical, electromagnetic, ultrasonic and other types of heat meters, but because of the high price and low accuracy of these heat meters (the general measurement accuracy is only about 2%) And because the problem of the measured medium in the pipeline affects the service life of the instrument itself, the above-mentioned heat meter has not entered the family for the time being, and is only used on the main heating pipe.
