6-62 ADS Portable FlowShark Pulse Manual
Please refer to the Manning-Strickler Coefficient table in Appendix C
for more information.
Manual
Enter the current depth and flow velocity obtained through a manual measurement.
The unit will calculate the theoretical discharge curve from these values.
This function may be used in conjunction with the automatic mode. The theoretical
settings designated for the measurement location (at which the flow velocity readings
are taken) will be verified using this method.
Manually setting v-crit determination
Assistant
The Portable FlowShark Pulse will guide you through a menu involving a simulated
obstruction (such as a sandbag) to determine the necessary characteristics and then
automatically generate a theoretical discharge curve.
This function may be used in conjunction with the automatic mode. The theoretical
settings designated for the measurement location (at which the flow velocity readings
are taken) will be verified using this method.
To begin this process, verify the discharge is flowing freely and then initiate depth
measurement by selecting ENTER.
Assistant – start measuring v-crit determination
The Portable FlowShark Pulse will execute the first depth measurement under free
flow conditions. This reading will take 8 seconds to complete.
