[0002] Flow meters are well-known devices that are used to measure the flow rate of fluids, such as liquids or gases in pipes. When measuring the flow rate of the fluid in the pipe, the flow meter needs to be installed in the pipe first. Flow meters can be classified into external clamp type, pipe section type, and insertion type according to the device installation method. In the installation scenario of the flow meter, the external clamp type and the insertion type require the probe to be positioned on the pipe, and the insertion type requires an opening to be made at the positioned location to install the probe.
