Why do the rotors in remote-transmission rotor flowmeters tend to get stuck? How to improve?

This post was last edited by ylb913 on 2015-10-23 at 13:30; the issues occur when the media is dirty. A filter can be placed in front of the flow meter. Add a control valve to adjust the flow rate from time to time over short periods, thereby moving the rotor. If nothing else works, frequent cleaning is the option.

Install a magnetic filter in front of the flow meter.

The remote transmission part of the remote-transmission rotor flowmeter relies on magnetism to couple with the rotor. Although the medium to be tested has been filtered, some of the small magnetic particles in it inevitably end up inside the conical tube and are attracted by the magnet at the upper end of the rotor. The gap between the moving parts and the conical tube gradually decreases, resulting in friction and causing stagnation. Furthermore, over time, scaling on the pipe walls causes the rotor to become inflexible up and down. The improved methods are: first, to regularly disassemble and clean the rotor in order to remove the ferromagnetic substances that get stuck to it; second, to install a \"magnetic filter\" on the pipeline in front of the instrument, preventing ferromagnetic substances from entering the cone-shaped tube. The simplest solution is to install magnets at an appropriate location in the existing filter.

After reading your introduction, I’ll give it a try then. It’s going to be troublesome!

I’ve learned something new; I used to encounter such problems too

Only filters and cleaning pipelines can be added.

With the current design, jamming of the rotameter is a common problem; unless the design is changed, manufacturers will tell you that the pipeline is dirty, contains impurities, and that the cleaning process was not thorough – when the device is taken apart, the inside of the pipeline is filled with black powder. Unless the design is changed, this issue will persist
