Embodiment Construction

[0039] The thermal drip meter of the present invention is equipped with a thermal drip flow measuring device on the base meter of the impeller type water meter to form a thermal drip meter. Flow rate, for example, the normal water flow rate is greater than 3L / h; the thermal sensing drip flow measuring device is used to measure the drip flow rate of water users, for example, the drip flow rate is less than 3L / h, the highest value of the drip flow rate is the impeller-type water meter, the base meter impeller can be controlled by tiny flow water The minimum flow to push.

[0040] The thermal-sensing drip meter and the thermal-sensing drip measuring method of the present invention will be further described below in conjunction with the accompanying drawings.

[0041] Such as figure 1 As shown, the thermal drip meter of the present invention includes an impeller-type water meter base meter and a thermal drip flow measuring device. The base meter of the impeller type water meter ...

Abstract

The invention relates to a thermal sensitive type drop water meter. The thermal sensitive type drop water meter consists of an impeller type water meter base meter and a thermal sensitive type drip flow measuring device, wherein the thermal sensitive type drip flow measuring device comprises a dial box with an air vent, an environmental temperature sensor, a fluid temperature sensor, a processor and a circuit board. The impeller type water meter base meter measures normal water flow GY of a water user, the thermal sensitive type drip flow measuring device measures water temperature TW in a water outlet pipe of the base meter and environmental temperature TO, and water processing program built in the processor and the circuit board judges and calculates drop water flow of the water user according to temperature difference TC which is equal to an absolute value of TO minus TW. The thermal sensitive type drop water meter and the drop water measuring method have the advantages that not only can the normal water flow of the water user be measured, but also the drop water flow can be measured, the structure of the water meter is simple, the water meter is economic and practical and is not influenced by water quality, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of water flow detection, in particular to a thermal drip meter and a thermal drip measurement method. Background technique [0002] The water meter is a metering tool used to measure the water consumption of water users. Its working principle is: the water flow from the water inlet of the water meter hits the impeller, the impeller rotates and transmits it to the counter, and the water consumption of the water user is recorded by the counter. However, the existing water meters all have a flow measurement lower limit. When the water flow through the water meter is drip flow, the drip flow is a flow lower than the flow measurement lower limit of the water meter. Flow reading is zero. Due to this technical defect of the existing water meter, the drip flow cannot be measured. According to statistical data, existing water meters cause about 10% of annual economic losses to water supply companies because of the ...
