　　3、 Installation:

　　1. There should be no strong external magnetic field interference or strong mechanical vibration around the flowmeter. Before installation, the environmental conditions should be reviewed according to its usage requirements for normal use;

　　2. When installing the flowmeter outdoors, there should be a cover on the upper part to prevent rainwater from entering and direct sunlight from affecting the service life of the flowmeter;

　　3. The flowmeter can be installed at any angle, and the direction of fluid flow is consistent with the direction indicated on the housing. There are straight pipe sections of 10DN and 5DN upstream and downstream of the flowmeter, respectively;

　　4. The flowmeter should be installed coaxially with the pipeline, and the flange screw hole connection should be parallel to the pipeline axis, to prevent the sealing gasket and grease from entering the pipeline cavity;

　　5. If necessary, a filter can be installed upstream of the flowmeter to filter out particles and debris in the medium;

　　6. When installing flow meters and measuring pipelines, consideration should be given to installing expansion pipes and corrugated pipes, and the upstream and downstream pipelines should be laid reasonably according to the actual size of the flow meter, so as to minimize the deformation of the flow meter caused by pipeline stress.
