How to maintain glass rotameters

Thread Content

Generally, professional maintenance of glass rotameters requires skilled personnel, but daily maintenance can be carried out by the operators themselves, which saves time and also extends the instrument’s service life. While maintaining the instrument, it is also necessary to master its correct usage. 　　1. Upon receiving the glass rotameter, first check whether the glass tube inside it is intact, as the glass tube can easily break. Next, remove the fixings of the rotor and gently tilt it to check whether the rotor can slide up and down freely. If it cannot slide freely, gently vibrate the support plate; this usually allows it to slide. If it can no longer be slid, it will be necessary to hire a professional technician to disassemble the device and fix the issue. 　　2. When installing on the pipeline, first check whether the upstream and downstream pipelines are in a straight line. If they are not on a straight line, it will not only affect the measurement accuracy of the instrument but also damage it. 　　4. Use safely; some operators like to remove the front cover for use, but this is not allowed, as the glass tube can break easily and the cover serves as a protective layer. Therefore, the cover cannot be removed for use, and care must also be taken in maintaining the cover. 　　5. When using it in winter, it is important to keep warm. If it is not used at night, be sure to drain the liquid remaining inside the flow meter to prevent the glass tube from freezing and breaking. 　　There are various methods for maintaining glass rotameter flow meters, but regardless of the method used, the primary goal is to ensure the proper functioning of the instrument, thereby extending its service life.
