14 Instruction Manual
2.7.4 W-method Installation
W-method is usually used on plastic pipes with a diameter from 15mm to 50mm.
2.7.5 N-method Installation
N-method is used for small pipe size. But W-method has more often used than N-method.
Thus, N-method is rarely used method in fact.
2.8 Installation Checkup
Through the checkup of the installation, one can: check the receiving signal strength, the
signal quality Q value, the traveling time difference of the signals, the estimated liquid
speed, the measured traveling time of the signals and the calculated traveling time ratio.
Therefore, optimum measurement result and longer running time of the instrument can be
achieved.
