Parameter Settings 8-31
This section enables the user to set and assign the digital input signals Control
OPEN, Control CLOSED, and Torque CLOSED. The FlowShark Pulse Model 20
requires these input classifications for regulator operation.
The Lock v-measurement function is available only for digital input 1.

Locking measurements may be useful for challenging applications, such as locations
that characteristically reflect backwater conditions. The unit either releases or locks
the velocity measurement based on a limit value contact, such as a discrete echo
sounder, float switch, or conductive transducer, using the overflow height as the
switching threshold. Locking refers to setting the flow velocity readings to 0. Since
the unit will calculate volume as V=0, no analog or digital values corresponding to
flow will be available.
However, selecting the option to save individual gates will ensure individual velocity
readings are saved.
Channel number
Select the appropriate digital input, from inputs 1–4, for which to set the following
parameters.
Name
