Installation problems are different for different principles of flowmeter requirements. For some flowmeters, such as differential pressure flowmeters and speed flowmeters, according to the regulations, a certain length or a long straight pipe section should be provided on the upstream and downstream of the flowmeter to ensure the full development of fluid flow before the inlet end of the flowmeter. . Other flow meters, such as volumetric flowmeters, float flowmeters, etc., have no requirements or requirements for straight pipe lengths. Other flowmeters have a certain error due to the influence of the installation.
The common problems are as follows:
1. Reverse the inlet surface of the differential pressure flowmeter orifice plate;
2.The flow sensor is installed in a place where the flow velocity distribution profile is poor;
3.The flowmeter is installed in a hazardous environment or inaccessible places;
4. The flow direction of the flowmeter is incorrectly installed;
5. The flow meter or electrical signal transmission line is placed under a strong electromagnetic field;
6.Install a flow meter susceptible to vibration interference on a vibrating pipe;
7.Lack of necessary protective accessories.
