PAR: Velocity
The Portable FlowShark Pulse supports a flow velocity sensor housed in a water-
ultrasonic combination sensor with integrated depth measurement or as a standalone
water-ultrasonic velocity sensor.

Choosing sensor type displays the following screen:
Selecting the sensor type
Sensor Type
Choose the wedge (combination) or pipe insertion sensor and float (measurement
from above) or Pos-alpha (positioned at any angle up to vertical) using the ALT key.
Installation position is set to positive by default. Do not modify this parameter. The
negative setting exists only for specific applications where the flow velocity sensor is
facing downstream (the sensor faces upstream toward the oncoming flow during
standard applications), but is used to measure positive velocities.
Mounting Place
This parameter allows you to modify the installation height for the flow velocity
sensor. The default setting is 0 inches, which represents the bottom edge of the
ground plate (pipe bottom). This setting does not require modification unless the
sensor has been installed at an elevated position. If the sensor has been installed
higher, add the additional mounting height to the standard mounting height of 0
inches.
When selecting Pos-alpha, the following mounting settings are available for input:
