Water meter or flow meter structure based on resistance strain sensor

Abstract

The invention discloses a water meter or flow meter structure based on a resistance strain sensor. The structure comprises a measuring pipe section and a measuring host arranged outside the measuringpipe section, the measuring pipe section is provided with a fluid channel, a packaging part is fixedly arranged on the measuring pipe section and can deform when force is applied onto the packaging part, the resistance strain sensor is arranged in the packaging part and sealed and insulated by the packaging part, the resistance strain sensor comprises an elastic element and a resistance strain sheet, the elastic element simultaneously extends into the fluid channel along with local of the packaging part and deforms based on impact of fluid, the resistance strain sheet is arranged on the surface of the elastic element in a fitted manner, resistance of the resistance strain sheet is changed along with deformation of the elastic element, the resistance strain sheet is electrically connected with the measuring host, and a resistance value of the resistance strain sheet is transmitted to the measuring host. The structure has the advantages that a structure of a traditional mechanical watermeter is changed, and a mechanical structure of the water meter is transformed into an electronic mode, so that good bases are provided for multi-function and intelligence of the water meter and the flow meter.

Description

technical field [0001] The invention relates to the field of water meters and flow meters, in particular to a water meter or flow meter structure based on a resistance strain sensor. Background technique [0002] At present, most of the water meters on the market are mainly composed of mechanical parts such as impellers, water flow guides, and transmission gears. Their single structures can only be used for water volume statistics, and it is difficult to expand other functions. Therefore, it is very necessary to improve the structure of traditional water meters and flow meters, and to expand the diversification of their functions. Contents of the invention [0003] The purpose of the present invention is to provide a water meter or flowmeter structure based on resistance strain sensor, which changes the structure of traditional mechanical water meter, and changes the water meter from mechanical structure to electronic mode, so as to provide multi-functional and Intelligen...
