在锥管中的高度与所通过的流量有对应关系。该高度就是流量大小的量度。

用在浮子上的上升力与浮子所受的重力、浮力及粘性力三者的合力相等时，浮子便稳定在某一高度上。这时浮子

01 产品概述 Product Overview

Product Features

Glass rotor flow meter (hereinafter referred to as flow meter) is one of the instruments used to measure the flow of nonturbid liquids, gases and other single-phase medium. The measuring part of the instrument consists of a vertically mounted

glass cone tube and float inside the tube. The large end of the cone tube is upward, and the float moves up and down in the

direction of the cone tube axis with the flow rate as it increases or decreases. The large end of the cone tube is upward, and

the float moves up and down in the direction of the cone tube axis with the flow rate as it increases or decreases. The rising

force acting on the float is equal to the combined force of gravity, buoyancy and viscous force on the float, the float is

stabilized at a certain height. At this time, the height of the float in the conical tube corresponds to the flow rate through it.

That height is a measure of flow rate.

The meter has the advantages of simple structure, easy maintenance and use, low cost, and so on. Mainly used in

chemical industry, petroleum, light industry, medicine, chemical fertilizer, chemical fiber, electric power, metallurgy, food,

sugar, fuel, paper, environmental protection, new energy and scientific research departments.

Adjustable micro flow rate.

Low pressure loss.

Reliable performance.

Simple structure, easy

installation and use.
