Under normal circumstances, the installation pipe diameter in the range of DN15-200mm can be preferred V method, the V method can be used when the signal is not detected or the signal quality is poor, and the Z method should be preferred when the pipe diameter is above DN200mm or the measurement of cast iron pipe. The N method and the W method are less used methods, which are suitable for the installation of thin pipes under DN50mm.
The V method is a standard installation method, which is convenient to use and accurate to measure. When installing, the two sensors are aligned horizontally, and the center line is horizontal with the pipe axis. The diameter range of the pipe can be measured is DN15mm-DN400mm.
N method installation N method installation is characterized by extending the ultrasonic transmission distance to improve the measurement accuracy. When the N-method is used for installation, the ultrasonic beam is reflected twice in the pipe and passes through the fluid three times (called triple path), which is suitable for measuring small-diameter pipes.
The same as the installation of the N method, the installation of the W method also improves the measurement accuracy of the small pipe diameter by extending the ultrasonic transmission distance. The W method is suitable for measuring small tubes below 50mm. When installed using the W method, the ultrasonic beam is reflected in the tube three times and passes through the fluid four times.
