Explosion Proof Metal Tube Rotameter Acrylic Rotameter Working Pressur 1mpa

Product Description

Metal tube float flowmeter consists of measuring pipe, float, indicator and process connection components with the characteristics of small size, wide measuring range, easy installation. In the industry area, it is widely used to measure flow of gas, liquid, and steam, especially suitable for mediums with low current velocity and low flow rate.

The troubleshooting method of metal flow meter

First, the pointer of the metal tube float flowmeter stops at a certain position. The main reason is that the float of the metal tube float flowmeter is stuck.
Generally, when using the metal tube float flowmeter, the valve is opened too fast, the float quickly hits the stopper upwards, causing the stopper to deform and the floater stuck. However, it is not ruled out that the float is stuck because the float guide rod and the stop ring are not concentric.
During processing, the instrument can be removed, the deformed stopper can be removed and reshaped, and check whether it is concentric with the guide rod. If not, you can correct it, then install the float, push the float by hand, and feel that the float is smooth.
In addition, the metal tube float flowmeter must be installed vertically or horizontally when installed, and cannot be tilted, otherwise it may easily cause card meters and bring errors to the measurement.
