VOLUME FLOW MEASUREMENT
In building and process technology, it is necessary to
measure the quantities of air flowing into rooms or
processes or being circulated in the plant. The quantity
of air transported in a given period of time is known as
the volume flow (most common unit: m 3 or ft 3 per hour).
Accuracy down to the last decimal point is not usually
critical in these applications. The key features are reliability, robust build quality and good value for money.
The most commonly used method of measuring volume
flows is based on the principle of differential pressure.
This has a number of specific advantages:
xx
low investment costs, especially for ducts with
medium or large cross-sections
xx
minimal calibration costs
xx
process technology: can also be used in plants
where temperatures differ significantly from room
conditions
Please note that the differential pressure method of
measuring volume flow cannot accurately record very
small volume flows. These low measurement values
are therefore suppressed (creep suppression), e.g. the
lowest 3 % of the differential pressure measurement
range. However, in typical air conditioning and ventilation
systems, as well as in most process technology plants,
the volume flows lie between 20 and 100 % of the maximum measurement range so this does not result in any
significant limitations.

PRIMARY ELEMENTS – MODE OF OPERATION AND SELECTION
In order to convert the volume flow into a differential
pressure, so-called primary elements are installed in the
air duct or process. This either constricts the cross-section concentrically (orifice plate, cone, venturi).
orifice opening
orifice
Or the sum of the static and dynamic pressure is measured and recorded (pitot tube, flow tube, Wilson flow
grid) at one or several points and the static pressure subtracted. The latter group of primary elements offer the
advantage that there is only a minimal loss of pressure
– which noticeably reduces operating costs!

We are also pleased to offer primary elements for process technology or customer-specific applications, see p. 13

Pitot tube and flow probes: length must be less than the width
of the air duct. Flow grid: please state precise dimensions.
Straight inlet (= 10 D) and outlet (= 5 D) pipes are ideal (D = inner diameter)
Recommended for on-site adjustment: Multi-point flow measurements in accordance with DIN EN 12599 (average
value calculated from multiple measurement points per m2 of cross-sectional area). Please enquire about our range
of services (see p. 47). You can find further accessories on p. 21.

Delivery of completely calibrated
volume flow measuring sections
Measuring facilities that deliver a precise volume flow value are needed in machine and plant construction, as well
as in climate technology. On-site calibration is often not
economically efficient. For these applications, halstrupwalcher offers complete solutions that include the pipe / air
channel section (with a diameter of 25 .. 700 mm) as well
as the installed primary element and measuring transmitter, if required incl. tubing and control cabinet. Multi-point
calibration at our volume flow calibration stand completes
this overall solution.
VOLUME FLOW MEASUREMENT IN PROCESSES
Accurate measurement of volume flow in air ducts or ventilation systems (e.g. in m 3 / h or ft 3 / h) is becoming increasingly
important. This is because volume flow is an important process
technology parameter, e.g. for ensuring a specific drying quality
or the ability of a test facility to function correctly. But it is also
essential to monitor minimum volume flows in critical air-conditioning systems, such as those used for cleanrooms.
Your volume flow partner, halstrup walcher
xx p
rovides support in designing measurement points and primary elements (incl. optional temperature sensors)
xx takes responsibility for installation on-site
xx calibrates and adjusts equipment on-site
This ensures that all the installation conditions (and resulting
asymmetries of the flow profile) are taken into account to
produce the optimum result.
For process technology, halstrup-walcher supplies process
probes with optimised geometries (see photo). As you can
see from the flow simulation, these prevent the generation of
vortexes, which are created by standard flow pressure probes.
Higher accuracy and lower sensitivity to shorter inlet routes
are the results.
The following design parameters must be stated: medium (air
or non-aggressive gases), temperature (special versions for use
at temperatures > 400 ° C are possible), static pressure (up to 6
bar), design volume flow (e.g. 5 000 m 3 / h), air duct dimensions
or installation dimensions as well as the ambient conditions
(indoor, non-Ex, …).

P 26 AIR METER / MEASUREMENT OF AIR CONSUMPTION
APPLICATION
Today, it is very rare to measure air consumption for individual users. Costs are usually apportioned based on the total costs and the respective share of the total area occupied. For example, a tenant renting 23 % of the total area will
always pay 23 % of the air-conditioning costs. This is unfair in terms of user behaviour and different air conditioning
requirements for different room types – and importantly it offers no incentive to find savings. However, particularly
in commercial properties which are rented out to a number of tenants, air consumption is seen as being identical to
other consumed media (electricity, water, etc.) and there are demands for these costs to be apportioned fairly in the
same way, i.e. based on actual con2/3
1/3
sumption. The same applies

The P 26 air meter takes
the following approach:
based on the volume flow
measurement using the
principle of differential
pressure (please select a
suitable primary element,
see p. 12), the P 26 air meter adds up and displays
the volumes consumed
(m 3 or ft 3 of air) and
makes the data available
via a pulse output (optionally also via M-bus).

c) LEGALLY SECURE ON-SITE calibration
After the primary element and P 26
differential pressure transmitter have
been mounted, the latter is parameterised and adjusted on the basis of an
on-site calibration. This is legally secure
and traceable to national standards.
Adjustments are made either via a
user-friendly operating menu or using
simple PC parameterisation software.
This software is available to download
from our website. halstrup-walcher is
also pleased to offer services for complete on-site commissioning of
the air meter measurement point; see also p. 47.
