Electromechanical separation water meter

Abstract

An electromechanical separation water meter comprises a base meter main body, a base meter upper cover and an electric control main body, the base meter main body comprises a dial plate and dial plateglass, the dial plate is provided with a communication pointer used for non-magnetic sampling, the upper surface of the dial plate glass is partially sunken to form an assembly groove, the electric control main body comprises an induction end, and the induction end abuts against the assembly groove of the dial plate glass and is opposite to the communication pointer. According to the electromechanical separation water meter, the dial plate glass adopts organic glass, and a groove is formed in the surface of the dial glass; the induction end of the electric control main body can be assembled in the groove; compared with the prior art, the induction distance between a communication pointer and the induction coil is effectively shortened, the situation that sampling cannot be achieved due tothe fact that the induction distance is not enough is avoided, non-magnetic sampling of the electromechanical separation water meter is more stable, the induction end of the electric control main body is assembled in the groove in the surface of the dial plate glass in an embedded mode, the anti-interference function is achieved, and reliability is higher.

Description

technical field [0001] The invention relates to the technical field of fluid measuring devices, in particular to an electromechanical separation water meter. Background technique [0002] With the development of the times, smart water meters have gradually replaced some traditional mechanical water meters and have been widely used. With the development of electronic technology, the measurement methods of smart water meters are becoming more and more diversified. Mechanical meter detection, ultrasonic detection, magnetic detection and other methods have come out one after another. Compared with traditional mechanical water meters, the measurement methods of smart water meters are very different. Great improvement, but these methods still have obvious limitations, for example: easily affected by external electromagnetic interference, or because of the cumulative adsorption of impurities in water by permanent magnets, resulting in measurement errors or being used artificially a...

Problems solved by technology

[0003] In the current non-magnetic metering water meter manufacturing industry, a major technical bottleneck is that non-magnetic sampling is limited by the sensing distance. Under the premise that the industry standard stipulates the minimum thickness of tempered glass on the base meter dial, plus the plastic case of the electronic control part The thickness of the wall, the gap between the sampling pointer and the tempered glass, and the gap between the circuit board and the inner wall of the plastic case make it difficult to ensure the sampling distance of the existing non-magnetic sampling water meter at a stable sampling level, resulting in insufficient sampling or In the case of inaccurate measurement, at present, the problem of insufficient trigger distance is mainly solved by increasing the size of the stainless steel sheet on the communication pointer or increasing the power consumption of the sensing circuit. Although these two changes can improve the trigger sensing problem, they also lead to The new problem is that when the stainless steel sheet is enlarged without changing the movement, the stainless steel sheet will easily interfere with the inner wall, and increasing the power consumption of the induction circuit will shorten the service life of the battery
