NORTEK VECTRINO VELOCIMETER

Rev. C • 10.2004
The velocity in water (left part of
the graph) and in air (right part of
the graph).
7 Put the transducers in the water and observe the velocity, the standard devia-
tion and the amplitude in counts. Watch the graphical view of the velocity as
the probe goes in and out of the water. In air the graphs are noisy, while in
water they should be smooth. Note that the difference depends on the size,
shape and material of the bucket. If the velocity graphs remain weak with the
probe in water, try varying the position of the probe or add some seeding to
the water in the form of dirt or small particles.

Temperature should be close to your room temperature, assuming the Vec-
trino has been in the room for a while. To calibrate the temperature sensor
– see Verifying and Calibrating the Temperature Sensor later in this chap-
ter.
