Velocity Device

Edit the velocity device in the following way. These instructions
apply to all monitors using a velocity device except for the
FlowShark. For instructions on editing the velocity device

(FlowShark) on page 2-112.

Edit Velocity Device Properties

Note: Typically, the velocity device should not require
editing. However, when editing is necessary, ADS does
not recommend changing velocity parameters without
proper training or assistance.

• Flow Select the option from the drop-down list that

accurately represents typical flow conditions in the pipe. This
ensures the monitor applies the best algorithm for calculating
velocity. ADS recommends choosing the Fast (default)
option for pipes with flows commonly exceeding 1.5 feet per
second.

• Sensitivity Select the appropriate velocity sensor sensitivity

from the drop-down list. A sensitivity that is too high may
produce noise, causing interference in the signal and resulting
in spikes in the data. A low sensitivity can produce readings
