Length
The track length (L) is the distance between the two transducer windows in the same track.
Angle
The angle (
θ
) is the track angle, i.e. the angle between the track and centerline of the pipe.
Type SONOKIT will have a default angle close to 45° for DN 100, DN 125, DN 150 and 60° for
DN 300 - DN 4000.
Displacement
The track displacement (h) is the distance between the track and the centre plane of the pipe.
In case of a one track system where the track is placed in the centre plane of the pipe the
displacement is 0.
ZERO ADJUSTMENT
The factory setting is applicable in most cases, but if the user requires a very high accuracy at low
flow, an application-dependent zero adjustment, NEW AUTO ZERO, is recommended.
Zero adjustment is initiated when the LOCK key is pressed. The zero adjustment will take approx.
60 seconds. During the process the text BUSY and a countdown from 300 is displayed. When the
process is finished the value 0.0000 is displayed.
If the meter detects flow in the pipe during the zero adjustment process, the zero adjustment
process is interrupted and an error message displayed.
The signal converter stores the result of the previous zero adjustment in the register with the
extension "OLD".
