1) If the pipe parameters are correctly entered.

2) If the actual mounting spacing exactly coincident to M25 value.

3) If the transducers are installed properly in the right directions.

4) If the straight pipe length is enough.

5) If the preparation work has been done as described above.

6) If the pipe is distorted or if there is too much fouling inside.

Note: To ensure 1-6 are no problem, and then you can fine adjust the transducers distance to make sure TOM/TOS=97-103% in menu91. The closer to 100%, the better.
