Flowmeter with protective structure

Abstract

The invention relates to a flowmeter with a protective structure. The flowmeter comprises a fluid pipeline, a flowmeter body arranged on the fluid pipeline and a protective cover arranged outside the flowmeter body, the protective cover is detachably connected with the flowmeter body, an observation window is formed in the surface of the protective cover, and an observation plate is arranged at the position, located on the observation window, of the protective cover. The top of the protective cover is fixedly connected with an air supply cavity, the air supply cavity is communicated with an air outlet assembly, the air supply cavity extends out of the front side of the protective cover and extends outwards to form an extending part, the bottom face of the extending part is provided with an air outlet slope, the surface of the air outlet slope is provided with air outlet holes, and the air outlet holes face the observation window. The protective cover is arranged outside the flowmeter body, the flowmeter is protected, faults caused by the fact that an external object collides with the flow meter are avoided, the waterproof and dustproof effects are good, workers can check data conveniently through the observation window, in addition, the air outlet holes blow air to the surface of the observation window, and reading is prevented from being affected by dust falling on the observation plate.

Description

technical field [0001] The invention relates to the technical field of flow meters, in particular to a flow meter with a protective structure. Background technique [0002] Flow measurement is one of the components of measurement science and technology. It is closely related to national economy, national defense construction, and scientific research. Doing this work well is of great importance to ensure product quality, improve production efficiency, and promote the development of science and technology. role. Nowadays, according to the use requirements, some flowmeters are installed outdoors, and there is no corresponding protective structure for the head of the flowmeter, which may cause failure due to external factors and cause economic losses. Exposure to the outside causes dust to accumulate and affect readings, causing trouble and inconvenience in use, so further improvement is needed.
