Flow meter installation requirements and environmental factors to be considered

Abstract: The information on the installation requirements of flow meters and the environmental factors that should be considered are provided by the excellent manufacturers of flow meters and flow meters. Flowmeter installation 1. Problems to be paid attention to during installation Installation problems have different requirements for flowmeters with different principles. For some flowmeters, such as differential pressure flowmeters and velocity flowmeters, according to regulations, the upstream and downstream of the flowmeter must be equipped with a certain length. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the installation requirements of flowmeters and environmental factors that should be considered. Installation of flowmeters 1. Problems to be paid attention to during installation Installation problems have different requirements for flowmeters of different principles. For some flowmeters, such as differential pressure flowmeters and velocity flowmeters, according to the regulations, a certain length or a long straight pipe section should be equipped upstream and downstream of the flowmeter to ensure that the fluid flow before the inlet end of the flowmeter is fully developed. . While other flowmeters, such as positive displacement flowmeters, float flowmeters, etc., have no or lower requirements on the length of straight pipe sections. Some flowmeters have certain errors due to the influence of installation. For example, Coriolis mass flowmeters will bring great errors to use due to the influence of installation stress. Problems in the use of retrospective flowmeters may not necessarily be due to the problems of the flowmeter itself, and many situations are caused by poor installation. The common problems are as follows: ① Reverse the inlet surface of the orifice plate of the differential pressure flowmeter; ② The flow sensor is installed in a place with a poor flow velocity distribution profile; ④ The flow meter is installed in a harmful environment or a place that is not easily accessible; ⑤ The flow direction of the flow meter is installed in the wrong direction; ⑥ The flow meter or electrical signal transmission line is placed in a strong electromagnetic field; On the pipeline with vibration; ⑧ lack of necessary protective fittings. 2. Installation conditions The flowmeter should pay attention to the adaptability and requirements of the installation conditions during use, mainly from the following aspects, such as the installation direction of the flowmeter, the flow direction of the fluid, the configuration of upstream and downstream pipelines, valve position, protection Accessories, pulsating flow effects, vibration, electrical disturbances and flowmeter maintenance, etc. ① On-site pipeline wiring When wiring on-site pipelines, attention should be paid to the installation direction of the flowmeter. Since the installation direction of the flowmeter is generally divided into vertical installation method and horizontal installation method, the flow measurement performance is different for these two installation methods. For example, the vertical downward flow of the fluid will cause additional force to the flowmeter sensor, which will affect the performance of the flowmeter, and reduce the linearity and repeatability of the flowmeter. The installation direction of the flowmeter also depends on the physical properties of the fluid. For example, the horizontal pipeline may precipitate solid particles. Therefore, it is best to install the flowmeter with this state in the vertical pipeline. ② The flow direction of the fluid This problem is similar to the installation direction of the flowmeter. Since some flowmeters can only work in one direction, reverse flow will damage the flowmeter. The use of similar flowmeters also considers the possibility of reverse flow in the event of inactivity, which necessitates measures such as installing check valves to protect the flowmeter. Even a flowmeter that can be used in both directions may have some differences in measurement performance between forward and reverse, and should be used as specified by the manufacturer. ③ The upstream and downstream straight pipe sections of the flowmeter will be affected by the flow state of the pipeline inlet, and the pipe fittings will also introduce flow disturbance. The flow disturbance generally includes vortex and flow velocity distribution profile distortion. Caused by more than one space (stereo) elbow. Distortion of the velocity profile is usually caused by local obstructions in pipe fittings (eg valves) or elbows. These effects need to be ameliorated with upstream straight runs of appropriate lengths or the installation of flow conditioners. In addition to considering the influence of the flowmeter connection fittings, you may also consider the influence of the combination of upstream pipe fittings, because they may generate different disturbance sources, so be sure to keep the distance between the disturbance sources as much as possible to reduce their influence. For example, a partially open valve follows immediately after a single bend. A straight pipe section is also required downstream of the flowmeter to reduce downstream flow effects. For volumetric flowmeters and Coriolis mass flowmeters, they are not affected by asymmetric flow profiles; turbine flowmeters should be used to minimize vortex; electromagnetic flowmeters and differential pressure flowmeters should limit the vortex to a small within the range.

The use and installation of mass flow meter is compared with most other systems for managing the rosemount vortex flow meter effectively and no doubt mass flow meter have won the race so many times.
