10.7 Flow velocity distribution display function (future option)
It is possible to measure the fl ow velocity distribution in real time by the pulse doppler method
and to display the fl ow state in the piping.
Use this function for judgment if the fl ow rate measuring position is appropriate, for diagnosis
of fl ow, for research, testing and others.
This function is applicable to the following types.
Main unit type: Must be specified at time of purchase
(with fl ow velocity distribution display function)
Sensor type: Small Sensor (Bore diameter; I40 to 200mm Fluid temperature; –40 to +100ºC)
Medium Sensor (Bore diameter; I100 to 400mm Fluid temperature; –40 to +80ºC)
Large Sensor (Bore diameter; I200 to 1000mm Fluid temperature; –40 to +80ºC)
10.7.1 Installing Detector
(1) Processing of detector mounting surface
Remove rust, pitch, surface irregularity and others from the pipe surface, to which a sensor is to
be mounted, by the frame length of the sensor to be mounted, using thinner, sandpaper and/or
other appropriate means.
Note) If the piping outer circumference is wound with jute, remove the jute from the entire outer
circumference in a length that is frame length (L) + 200 mm.

(2) Installation of detector
(1) Wrap the belt around the pipe.
Small/Medium Sensor
Adjusts the length of the wire rope according to the
piping size, fi xes the wire on the pipe.
Large Sensor
(2) Fully screw up to the right side.
