Yokogawa RAMC flowmeter selection and troubleshooting

In chemical, petrochemical, water treatment, and situations where opaque, corrosive, or turbulent fluids need to be measured, short tube rotor flow meters are still the most intuitive and economical type of flow instrument on site. The Yokogawa Rota RAMC series adopts a vertical installation and upward flow measurement method. The float is guided concentric inside a special conical metal tube, and its position is transmitted to the indicator through magnetic coupling. Therefore, mechanical indication can be achieved without the need for power supply, with low pressure loss and suitable for long-term online operation. For engineers, the difficulty of RAMC is usually not whether it can be measured, but whether the process connection, temperature and pressure boundary, liquid material, limit switch, intrinsic safety or explosion-proof certification, installation of straight pipe sections, and gas application back pressure are all confirmed clearly at once when selecting. Taking on-site selection, installation, and troubleshooting as the main line, combined with key data in technical materials, a set of practical reference ideas is provided below.
