Heating Pitot heat meter

Abstract

The invention discloses a heating Pitot heat meter which comprises a Pitot flow meter, an inlet temperature sensor, an outlet temperature sensor and a heat integrating meter. The Pitot flow meter is used for measuring flow of liquid in a pipeline, the inlet temperature meter and the outlet temperature meter are used for respectively measuring the temperature of liquid at a liquid inlet end of the pipeline and the temperature of liquid at a liquid outlet end of the pipeline, a signal output end of the inlet temperature sensor and a signal output end of the outlet temperature sensor are connected with signal input ends of the heat integrating meter, the Pitot flow meter is provided with a flow integrating meter, and a flow signal output end of the flow integrating meter is connected with a signal input end of the heat integrating meter. The heating Pitot heat meter has the advantages that the heating Pitot heat meter is simple in structure, convenient to mount and low in purchasing cost; the Pitot flow meter is high in measurement precision which can generally reach the 1.0 level, is quite suitable for measuring heating heat of domestic consumers, is wide in liquid medium application range and is anti-blocking and anticorrosion, influence of measured media in the pipeline on the service life of the heating Pitot heat meter can be prevented, and the like.

Description

technical field [0001] The invention relates to a heat meter for heating, in particular to a Bitoba heat meter for heating which is 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 aff...

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.
