FLOW VELOCITY PROFILE DISPLAY FUNCTION
(OPTION)
Pulse Doppler method enables the analysis and display of
the fl ow velocity profi le in real time. The results can be used
to decide the appropriate measurement location, for fl ow
diagnosis, and laboratory test.
SPECIFICATIONS
Measuring fl uid:
Uniform liquid in which ultrasonic
waves can propagate.
Turbidity of fl uid:
Axisymmetric fl ow in a fi lled pipe.
Fluid temperature:
−40 to +100°C (FSDP2)
−40 to +80°C (FSDP1,FSDP0)
Air bubble quantity:
0.02 to 15vol% (Velocity is 1m/s)
Pipe size:
Small type sensor : ø40 to ø200mm
Middle type sensor :ø100 to ø400mm
Large type sensor :ø200 to ø1000mm
Measurement range:
0 to ±0.3 … ±Maximum Velocity (de-
pending on the pipe diameter)
Refer to chart, page 145.
Note) This function is to observe fl ow
velocity profi le, and it may be different
from actual fl ow rate.
