Abstract

The invention relates to an environmental monitoring type anti-freezing water meter. The water meter comprises a water meter body and an intelligent control module arranged below the body; the intelligent control module comprises an amplification circuit, an A / D conversion module, a single-chip computer and a switching circuit; an electric heating wire is arranged in the body; a temperature sensoris arranged in the body, the temperature sensor is electrically connected with the input end of the amplification circuit through a guiding wire, the output end of the amplification circuit is electrically connected with the input end of the A / D conversion module, and the output end of the A / D conversion module is electrically connected with the single-chip computer; the single-chip computer is electrically connected with the control input end of the switching circuit, and the switching circuit is electrically connected with a strong current power supply and the electric heating wire. According to the water meter, water in the water meter is heated by arranging the electric heating wire to prevent the water in the water meter from freezing and ensure that the temperature of the water in the water meter is above zero DEG C all the time, so that a full-scale anti-freezing effect is achieved to prevent the water flow in the water meter from icing and expanding resulting in damage of thewater meter, the manufacture process is simple and the prices of materials are low.

Description

technical field [0001] The invention belongs to the technical field of water meters and accessories thereof, and in particular relates to an environment monitoring type antifreeze water meter. Background technique [0002] A water meter is an instrument that measures water flow. Mostly cumulative flow measurement of water. It is generally divided into two types: volumetric water meters and speed water meters. The accuracy of the former is higher than that of the latter, but it has high requirements on water quality, and it is easy to be blocked when there are impurities in the water. The meter that records the water consumption of tap water is installed on the water pipe. When the user releases water, the pointer or character wheel on the meter rotates to indicate the amount of water passing through. [0003] However, there are different requirements for water meters in different regions. For example, in relatively cold areas, there are very high requirements for the cold...
