Problems solved by technology

[0003] The present invention aims to solve the technical problem that the flowmeter cannot be used normally due to impurities in the fluid medium being stuck between the float and the tapered glass scale tube wall during the operation of the existing glass rotameter, and provides a Filtered glass rotameter, the flowmeter can prevent the float from being stuck in the tapered glass scale tube by slightly changing the lower base without changing the flow characteristics of the measured fluid

Abstract

The invention relates to a filter-type glass rotameter comprising a water inlet pipe and a flow adjustment cavity. The filter-type glass rotameter is characterized in that a stainless steel gauze filter is arranged between the water inlet pipe and the flow adjustment cavity and is arranged in a filter cavity. By slightly improving the water inlet end of the minitype glass rotameter, the invention can change the phenomenon of stainless steel floater jamming because larger impurities exist in water when the rotameter runs.

Description

technical field [0001] The invention relates to a rotameter, in particular to a flowmeter with stainless steel floats used in piping systems. Background technique [0002] Glass rotameters are widely used in chemical industry, petroleum, light industry, medical treatment, chemical fertilizer, food, papermaking, environmental protection and synthetic fiber, scientific research and other units. It is a high borosilicate tapered glass scale tube and a stainless steel float that can float up and down in the tube. When the fluid flows through the tapered glass scale tube from bottom to top, a pressure difference is generated between the upper and lower sides of the float, and the float rises under the action of this pressure difference. . When the rising force is equal to the gravity of the float, the float is in a balanced state. Therefore, there is a certain proportional relationship between the fluid flow passing through the flowmeter, the rising height of the float and the f...
