VGS VELOGRID
The VGS Velogrid has been designed to measure air volume in
ventilation ducts. The Flowgrid consists of a stainless steel duct
section with a length of 300mm and is available with a 30mm flange
duct connection to suit standard stainless steel duct work.
The CMR Veloprobes made of stainless steel are fitted across the
internal duct frame area in predefined spacing. Each Veloprobe has
a number of pressure inlet points to measure the impact and static
pressure at the same time. Both static and impact pressure ports of
the Veloprobes have independent pressure manifolds which
provides a smooth pressure signal of the whole measured area.
The differential pressure of both impact and static pressure is the
velocity pressure which can then be converted by the P-Sensor to
provide total air volume measurement.
Another great advantage of the VGS Velogrid is, that it can
measure bi-directional as it is manufactured equally on both sides.
This means, the air flow is measured in one direction and should
there be a reverse flow, this can be detected and measured when
using the CMR P-SENSOR. The installation direction is therefore
not important. The VGS Velogrids are manufactured in standard
height increments of 100mm going up to a maximum height of
1200mm.
The width of the Velogrid is manufactured in increments of 50mm
up to 1200mm. The Velorobes are fitted across the width and are
equally spaced over the height. If the duct height is 1000mm then
there will be 10 Veloprobe sets fitted into this Velogrid section.
Larger and fully welded Velogrids can be manufactured to order.

VGS VELOGRID
INSTALLATION
The VGS Velogrid ist best installed in a straight duct with a minimum
length before and after the Velogrid. A guide for duct length can be
calculated approximately by working out the duct area (h x w) in m2
multiplied by 1.2. This means, if the duct is 400mm high and 600mm
wide it would the following calculation:
0.4m x 0.6m = 0.24 x 1.2 = 0.288m is the minimum length before and
after the VGS Velogrid. The Velogrid does not work on a T-Section or
after a damper which moves and where the air blows head on into a
T-duct section which can cause the air to bounce back onto the
Velogrid. It can be installed vertical or horizontal but care must be
taken that the tube connections are either on the side or at the top.
Never at the bottom, as condensation might block the measurement
tubes.If the air is very turbulent a CMR Flow straightener can be
installed on the inlet of the Velogrid.
VGS Velogrid in a duct section
The VGS Velogrid can be installed after an elbow as shown on the
right. Best is to have room for a straight duct with a minimum length
before and after the Velogrid. A guide for duct length can be
calculated approximately by working out the duct area (h x w) in m2
multiplied by 1.2. This means, if the duct is 300mm high and 700mm
wide it would the following calculation:
0.3m x 0.7m = 0.21 x 1.2 = 0.252m is the minimum length before
and after the VGS Velogrid.
If this length is not available due to very short duct runs, then a CMR
Flow Straightener has to be installed in front of the Velogrid. The
Velogrid does not work after a damper which moves or where the
air blows head on into a duct section which can cause the air to
bounce back onto the Velogrid.
VGS Velogrid after elbow duct section
The VGS Velogrid can be installed after a T-Section shown on the
the right. Best is to have room for a straight duct with a minimum
length after the 'T' and before the Velogrid and a minimum length
after the Velogrid. A guide for duct length can be calculated
approximately by working out the duct area (h x w) in m2 multiplied
by 1.2. This means, if the duct is 800mm high and 1000mm wide it
would the following calculation:
0.8m x 1m = 0.8 x 1.2 = 0.96m is the minimum length before and
after the VGS Velogrid.
If this length is not available due to very short duct runs, then a CMR
Flow Straightener has to be installed in front of the Velogrid. The
Velogrid does not work after moving a damper or where the air
blows head on into a duct section which can cause the air to bounce
back onto the Velogrid.
VGS Velogrid after T- duct section
If the duct on the right cannot be fitted with a Velogrid then the
bottom Velogrid measures the total volume and the top Velogrid
measures what is left over. The difference is the volume which
passes through the duct on the right. Both Velogrids need room for
a straight duct with a minimum length before and after. A guide for
these duct lengths can be calculated approximately by working out
2
the duct area (h x w) in m multiplied by 1.2. This means, if the duct
is 500mm high and 500mm wide it would the following calculation:
0.5m x 0.5m = 0.25 x 1.2 = 0.3 m is the minimum length before and
after both VGS Velogrids.
If this length is not available due to very short duct runs, then a CMR
Flow Straightener has to be installed in front of each Velogrid. The
Velogrid does not work after a moving damper or where the air
blows head on into a duct section which can cause the air to bounce
back onto the Velogrid.

VELOCITY PRESSURES
If the P-Sensor was ordered separately and it was not factory
adjusted then it is quite simple to adjust the parameters on site.
CMR
The P-Sensor has a keyboard and the duct height and width must
be entered. The magnification factor of the VGS Velogrid must be
entered which is normally 2.667, if it is installed in a straight duct.
P-SENSOR
If the volume indicated on the P-Sensor display is deviating from the
actual measurements, then the magnification factor can be adjusted
to suit the installation abnormalities via the P-Sensor keyboard.
Airflow In
Adjust the fan to a constant volume – start with 50% of the minimum
and maximum operating volume and take a pitot travers reading
with a CAL150 instrument. Once the average volume has been
established and it is not the same as displayed on the P-Sensor,
then adjust the Magnification Factor (mf) until the same display is
achieved. For higher accuracy try this at 25%, 75% and 100%
volume set point The P-Sensor has also parameters to linearize the
measurements for more critical applications.
Airflow Out
Veloprobe in Velogrid is Bi-Directional
VGS Velogrid and P-Sensor tube connections
Useful VGS Velogrid scaling formula:
The velocity pressure is measured by the Veloprobes built into the
VGS Velogrid and the total impact pressure is measured on the
positive (+red) and the static pressure is measured on the negative
(- blue) manifold tanks The P-Sensor shall be connected to the
corresponding tanks using CMR PVC red and blue tube.

To get the range of the P-Sensor use the keyboard and display the range . This is the sensor range in m /s or m /h at 10V / 20mA. Enter
this range into your control system. No further calculations are necessary. If you want to use the table above, use the range of the
transmitter in Pa and divide it by the (mf) of the VGS. Look up the velocity above. i.e. 100Pa / 2.667 = 37.49 Pa.
Look up above ~ 37.5 Pa and read on side and top ~ 8 m/s then multiply with duct area in m2 to get m3/s and multiply 3600 to get m3/h.

SPECIFICATIONS
The duct area should be calculated so that the velocity is
approximately 2.5m/s at the minimum volume and preferably 5m/s
at the operating point if possible. If the velocity is more than 5m/s at
the maximum volume then the noise level criteria needs to be
considered.
The maximum velocity should not exceed 9m/s as the duct
resistance shall increase and the overall energy consumption shall
go up. Use selection Table 1 to 4 on page 5 to 8.
The VGS Velogrid has the advantage that it reduces the area
internally which increases the velocity pressure momentarily but will
have a regain of pressure after passing over the Veloprobes, which
means that the minimum velocity could go down to 1m/s and still
providing a reasonable velocity pressure measurement.
Should there be a lot of turbulence i.e. after a fan outlet then the
CMR Flow Straightener can be fitted before the VGS Velogrid so that
the air flow is laminar before it enters the VGS Velogrid.
Installation
The VGS Velogrid can be installed horizontally or vertically but the
tube connections should be on the side or on top. It works best if it
has a reasonable length of duct so that the air flow is laminar when
approaching the VGS Velogrid. If a reasonable length is not
available then the magnification factor (mf) can be adjusted on the
P-SENSOR and it can be linearized over 10 points for unusual
measuring positions. This is easily achieved by measuring the air
volume at a different location of the duct and adjusting the PSENSOR via the keyboard accordingly.

Maintenance
The VGS Velogrid is maintenance free and when used in
conjunction with the P-SENSOR there is no air flow going through
the Veloprobes and therefore no dust particles can enter the
measuring holes as they are pressurised and any particles would be
deflected from the Veloprobes.
