Description

Filtering type glass rotameter Technical Field The utility model relates to the technical field of glass rotameters, in particular to a filter type glass rotameter. Background Glass rotameters are a type of flow meter that is widely used in industrial production and laboratories. The device has the visual characteristic that a user can directly observe the position and the ascending height of the rotor through the glass tube, so that the flow can be quickly read. The measuring range is wider, and the measuring device can meet the measurement of different flow demands, and is adequate for accurate measurement of small flow or rough monitoring of large flow. The flow rate can be measured more accurately, whether it is a clear liquid or a fluid having a certain viscosity, which is excellent in measurement of various fluid media. And it has better corrosion resistance, and can work stably for some chemically active fluids. The glass rotameter is convenient to install, does not need complex operation and a large number of auxiliary equipment, can be directly installed on a pipeline for flow monitoring, and plays an important role in the industries of chemical industry, pharmacy, food processing and the like. According to the utility model disclosed in patent grant publication No. CN220751251U, the filter type glass rotameter comprises a filter box, a filter assembly and a fixing assembly, wherein one side of the fixing assembly is provided with a water inlet pipe, one end of the water inlet pipe is spliced with the filter box, one side of the filter box, which is far away from the water inlet pipe, is fixedly connected with a glass pipe, one end of the glass pipe, which is far away from the filter box, is fixedly connected with a fixing box, a water outlet pipe is spliced at the center of the fixing box, and a floater is arranged in the glass pipe.
