FUNCTION
A volumetric flow controller is used for pressure-independent
volumetric flow regulation in ventilation and air-conditioning
systems. It serves to keep the volumetric flow either constant
within specified limits (CAV) or to control it variably (VAV).
The housing, measuring nozzle and the controller with pressure
sensor form a closed control loop with feedback, allowing de-
mand-dependent, energy-saving air-conditioning of the single
rooms or areas of air-conditioning systems also at low duct
pressures and air velocities. When suitable controller types are
used, room or duct pressure regulation can be achieved.
For the measurement of the effective pressure, SCHAKO is us-
ing its measuring method by means of a standardised Venturi
nozzle made of aluminium to DIN EN ISO 5167. In front of the
Venturi nozzle and in the nozzle neck, the volumetric flow con-
troller is fitted with openings for pressure take-off. The result-
ing differential pressure (effective pressure) is measured and
evaluated by a universal or compact controller. The VLV meas-
urement principle allows measurement of small volumetric
flows. In comparison with measuring rods, measuring crosses
or measuring orifices having fewer measuring points, this gives
higher accuracy, allowing the inflow area required in front of
the volumetric flow controller to be omitted. This also allows
smaller measurement tolerances to be achieved.
The volumetric flow controllers of the VLV type are insensitive
to dirt caused by dust and can be installed and used inde-
pendently of their position. The mounting instructions docu-
mented by the manufacturer must be adhered to, as otherwise
the correct functioning of the volumetric flow controller is not
guaranteed. The volumetric flow controllers type VLV are not
suitable for air containing sticky and greasy particles (e.g.
kitchen exhaust air).

AREAS OF APPLICATION
for supply and return air systems with low pressures
and low air velocity
for constant CAV or variable VAV installations
for positive control Vmin, Vmid, Vmax, "OPEN" or "CLOSED"
For volumetric flow and linear pressure control
at ambient temperatures 0° to +50°C,
requirement: measuring air 0...+50°C/5...95% rH,
non-condensing
for regulating the air velocity in the duct in
the range of 0.5...8 m/s
VLV55 for air velocity 0.5 - 5 m/s
VLV65 for air velocity 1 - 8 m/s
Minimum pressure difference of 5 - 150 Pa
When using volumetric flow controllers in roof central units, in
extreme cases, condensation can build up in the measuring
pipes of the volumetric flow controller as a result of the large
temperature differences between the air flowing through the
volumetric flow controller and the surrounding air. This con-
densation may affect or damage the sensor. This is why for this
field of application care must be taken to insulate the housings
of the volumetric flow controllers and the measuring hoses (to
prevent condensation) and to mount the controllers in such a
way that any condensate formed on the outside of the measur-
ing hoses can run downward and be drained (without entering
the sensor).
When connecting SCHAKO components to customer installa-
tions, any compatibility problems are beyond our scope of re-
sponsibility and must be solved on site.

ATTENTION: Important for parameterisation of the VLV
The table corresponds to the complete measuring range.
When the air volume drops below Vmin, the correct function-
ing of the volumetric flow controller is no longer guaranteed.
If only Vmax is specified in the order, a variable volumetric
flow controller will be delivered. The Vmin value will be set to
the value specified in the catalogue.
If only one air volume is specified in the order (as Vmin or Vkon-
stant), then the volumetric flow controller will be delivered as
a constant volumetric flow controller. The volume specified
in the order is set to the Vmin value, and the Vmax value is set
to 100%.
The air volumes Vmin and Vmax and the operating mode 0/2-10
V can be changed directly at the controller within the nomi-
nal volumetric flow.
For the parameter setting of the control components, an air
density of 1.2 kg/m³ has been taken into account.
If no values are specified in the order, the controller will be
programmed with the values of the complete measuring
range. The following calibration curves are taken into ac-
count:
--- VLV55 ... 5 m/s;
--- VLV65 ... 8 m/s.
The first adjustment of the Vmin, Vmax and Vnenn operating volu-
metric flows is done prior to delivery ex works in accordance
with customer specifications (calibration for delivery address).
When these values are set, the functions of all volumetric flow
controllers are also checked.

TECHNICAL DATA OF CONTROL COMPONENTS
Measured value collection and control function
The volumetric flow controllers of the Belimo make, type LMV-
D3-MP/-MF Compact and the Gruner make, type 227VM Com-
pact are delivered by SCHAKO as standard with the operating
mode (Y signal, U5 signal) 2-10 V DC. When activated by 2 V DC,
the Vmin volume is controlled, the smallest possible Vmin volume
that can be controlled can be seen from the "Volumetric Flow
Range" tables.
NOTE: When the air volume drops below the Vmin shown in the
table, the correct functioning of the volumetric flow controller
is no longer guaranteed!
Positive control damper "CLOSED"
Airtight sealing to DIN EN 1751 is achieved on site either via a
positive control "CLOSED" by means of a switch or a relay, or
via an actuator signal of 0 V DC applied to the input Y (all Com-
pact controllers equipped with the operating mode 2-10V DC).
Accordingly, the drive will likewise close the flap in operating
range 2 - 10 V DC (however, this does not apply to the operat-
ing range 0-10 V DC), and the VAV control will be inactive. To
do so, it must be ensured that the actuator signal is < 0.1 V DC.
This is why in rooms where defined pressures are active (e.g. la-
boratories), the damper should be closed via a digital on site
switching contact.
If the Compact controllers of the Belimo make must be deliv-
ered with the operating mode 0-10V DC on customer request,
please note that a positive control "CLOSED" can only be ef-
fected via a switching contact with diode.
If the compact controllers of the Belimo make are used to-
gether with the type VRP-VFP-300 in the master/slave mode or
in parallel mode, then only the 2-10 V DC operating mode is
usually possible.
Positive control damper "OPEN"
Supports smoke extraction or is used as a safety position. The
volumetric flow controller is in this case inactive, and the
damper is driven to the mechanical open position.
Vmin control to a minimum volumetric flow
Depending on requirement or by not assigning them, individual
areas can be set to stand-by operation. In this way, minimum
room flushing with greatly reduced energy expenditure is
achieved.
Vmax control to a maximum volumetric flow
Individual or several rooms are supplied for a short period with
a maximum volumetric flow. This allows, for example, a room
through-ventilation or efficient heating to be effected.
Continuous operation
As a function of the continuous driving signal and the pro-
grammed operating range (0-10 V DC or 2-10 V DC), the volu-
metric flow controller will regulate the volumetric flow linearly
between the setpoint values Vmin ...Vmax.
Constant operation
If terminal 3 (Y driving signal) has not been assigned, the air vol-
ume set on the Vmin potentiometer will be set to a constant vol-
ume.
Two-stage volumetric flow rate control
Stage 1: If terminal 3 (Y command signal) has not been
assigned, the air volume set on the Vmin potenti-
ometer will be set to a constant volume.
Stage 2: If AC 24 V is applied to terminal 3 (Compact con-
troller) or terminal 7 (VRD3-SO, VRP-VFP-300),
the VSR will keep the value set on the Vmax po-
tentiometer constant. With a switch or a contact
in a connection line a "secondary volume flow
control" is possible.
