Problems solved by technology

The existing wet water meter is mainly composed of a watch case, a metering part installed in the watch case, an impeller part, and a master-slave transmission magnet. The chamber of the component and the impeller component are installed in the water flow chamber. After all the components are installed, the space in the watch case is basically fixed, that is, its volume remains unchanged. This constant volume is convenient for water meter measurement and installation, but When the outside temperature is lower than zero degrees Celsius, the accumulated water in the watch case is easy to freeze and expand, which will produce an outward extrusion force on the watch case and metering parts, and the glass plate will often be squeezed and broken, causing damage to the water meter

Description

technical field [0001] The invention belongs to the field of instrumentation preparation, and in particular relates to a preparation process of wet water surface plate glass. Background technique [0002] A wet water meter is a water meter with a counter immersed in water. The glass on the watch is subjected to water pressure. The transmission of the sensor and the counter is a gear linkage. The existing wet water meter is mainly composed of a watch case, a metering part installed in the watch case, an impeller part, and a master-slave transmission magnet. The chamber of the component and the impeller component are installed in the water flow chamber. After all the components are installed, the space in the watch case is basically fixed, that is, its volume remains unchanged. This constant volume is convenient for water meter measurement and installation, but When the outside temperature is lower than zero degrees Celsius, the accumulated water in the watch case is easy to ...
