Velocity Monitor
Setra’s Velocity Monitor is a multi-function non-BACnet device
designed to monitor velocity while also giving the user the option
to measure and display ow, dierential pressure, temperature and
humidity. The Velocity Monitor oers three velocity ranges as well
as three pressure ranges, giving the user the option to choose the
appropriate range for their application. The Velocity Monitor has a
3-color backlit display for easy menu navigation and audible/visual
alarm capability for velocity, ow, pressure, temperature, humidity
and door input. The velocity and ow measurements are based on
dierential pressure and require the use of a single point Pitot tube
or averaging probe.
Simplify Your Velocity Measurement
The Velocity Monitor oers velocity ranges of 2000 ft/min, 4000
ft/min and 8000 ft/min as well as three meter ranges of 0-10, 0-20
and 0-40 m/s. The Velocity Monitor automatically calculates the
velocity and volumetric ow rates based on dierential pressure,
eliminating the need for a manual square root calculation. Air
density correction can be set as a STD condition or use as a external
temperature sensor input.
Alarm Everything You Monitor
The Velocity Monitor provides audible and visual alarming for
velocity, ow, pressure, temperature and humidity to give you
peace of mind in your critical environment. High and low alarm setpoints for each parameter are easily congurable through a fourbutton membrane keypad. A digital input is also provided to show
door status.
Three Color Easy-to-See Status Screen
The Velocity Monitor utilizes a three-color backlit screen which
allows the end user to easily view the status of the monitored space
with green (normal), yellow (warning) and red (alarm) status screens.
Alarms can be congured to be delayed to ensure that each Velocity
Monitor is congured to the specic needs of the end user.
Save Time and Money on Calibration
With requirements in place to calibrate pressure sensors anywhere
from 1-3 times annually, the Setra Velocity Monitor oers a solution
to help you save on calibration time. The Velocity Monitor allows
the end user to remove the sensor without detaching any wiring or
plumbing, attach to the Setra calibration xture and complete the
calibration in minutes.
