Keywords of this article: Rosemount flowmeters. http://www.qyyb.net/ There are many things to keep in mind when installing Rosemount flowmeters. The author has provided information on using these flowmeters for measuring volatile substances, on the choice of installation location, and on the installation of flanges in process pipelines, in the hope of helping users in their subsequent use of these devices. Precautions for installing Rosemount flow meters: 1. When measuring easily vaporizable media, in order to monitor the downstream pressure, it is recommended to install a pressure gauge downstream of the flow meter ； It is recommended to maintain a certain distance between the process pipe and the flow meter with the same diameter, and to have a valve after the flow meter; this helps to prevent vaporization or cavitation, and can also be used to adjust the appropriate back pressure. If the medium vaporizes or cavitates in the flow meter, it will affect the measurement accuracy; in severe cases, it may render the flow meter inoperable. 2. On the upstream and downstream pipelines of the sensor, to facilitate zero adjustment, routine maintenance, and to ensure that the sensor remains in a full-pipe condition when not in operation, it is recommended to install stop valves and a bypass. Thereafter, the control valve downstream of the flow meter can be used for flow control. 3. The installation location should be free from electromagnetic interference. The installation locations of sensors and transmitters, as well as the routing of cables, should be kept as far away as possible from devices that generate strong electromagnetic fields, such as transformer installations, frequency conversion equipment, and high-power motors. 4. The process pipes must be aligned; the flanges on both sides should be parallel. There must be stable supports near the flanges on both sides of the process pipes. It is strictly prohibited to use the sensor to forcibly straighten the upstream and downstream process pipes, as this may affect measurements or even damage the sensor.
