FLOW VELOCITY PROFILE DISPLAY FUNCTION (OPTION)
Flow velocity profi le can be observed in real time using the dedicated detector from the outside. It is specifi able by the
code symbol of fl ow transmitter.
APPLICATION
Pulse Doppler method is applicable to observe fl ow velocity profi le in real time, display the fl ow status in the pipe, and
decide the appropriate measurement location. Also, it can be used for diagnosis of fl ow 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,FSDP1)
Air bubble quantity: 0.02 to 15Vol% (Velocity is 1m/s)
Pipe size: Small type sensor : φ40 to φ200mm
Middle type sensor :φ100 to φ400mm
Large type sensor :φ200 to φ1000mm
Measurement range: 0 to ±0.3: ±Maximum Velocity (depending on the pipe diameter) Refer to chart, page 139.
Note) This function is to observe fl ow velocity profi le, and it may be different from actual
fl ow rate.
