I/O: Sensors
This menu and the associated submenus allow you to view and assess the sensor
status and operational conditions. It provides information on the measurement
location quality, echo signal quality, and many other parameters.

Selecting this option displays a 2-page table that includes all the individual velocity
readings and the heights of the corresponding measurement windows.

Toggle between both pages (measurement windows 1-8 and 9-16) using the up and
down arrow keys.
The absence of a reading (------) in a measurement window indicates that flow
velocity currently cannot be measured in the corresponding window. This may occur
when the water is very clear or vorticity exists within the area. This also may occur

FlowShark Pulse automatically reduces the number of measurement windows
available. However, the failure of one or more windows does not determine
measurement success.
H-Sensor
H-Sensors indicate the depth levels measured. The submenus may vary based on the
depth sensor selected (water-ultrasonic, pressure, air-ultrasonic, or external sensor).
The following figures provide some examples:
