Configuration and Activation 6-17

Max Velocity

Select the appropriate option from this drop-

down list to fine tune the maximum velocity value at the

selected monitoring point for greater accuracy in the velocity

data. An Auto option is available that allows the monitor to

dynamically modify the optimal maximum velocity based on

the current velocity readings to enhance the precision in

processing velocity data. It can read velocities up to 30 feet per

second (fps). However, ADS recommends using a fixed value

for monitoring points that typically remain dry, such as

overflows or sites downstream from pump stations. For these

applications, consider choosing the 10 or 15 fps option,

particularly where a sudden surge of flow traveling at more

than 3 fps can occur within a single interval.

Sample Duration

Select the duration of time for the sensor

to fire based on the noise present at the location. This interval

should increase with elevated noise levels. ADS recommends

restricting the selected interval between 3 and 8 seconds.

Flow Type

Select the option corresponding to the conditions

that generally reflect the monitoring point at which the Doppler

velocity sensor is installed.
Typical

Choose this option for locations that consistently

experience continuous flow.

Wet/Stagnant

Choose this option for locations that

experience pooling, with only limited movement in the

flow.

Usually Dry

Choose this option for locations that are

characterized by an absence of flow, except during wet

weather conditions.

Gain

This represents the factor that is applied to raw velocity

to determine average velocity when receiving diagnostic

readings and calculating quantity and typical days in the

monitor. This parameter is editable through the Quantity
Coefficient Generator

tool in Profile.
