Description
Type S020
5. DESCRIPTION
The S020 fitting simplifies the installation of insertion devices for mea-
suring flow, pH, oxidation reduction potential (REDOX) or conductivity
on DN6 to DN400 pipes.
The fitting S020 is available in various versions for the installation of
measuring devices with a G2'' nut or measuring devices with a clamp
process connection.
The S020 measuring chamber is used:
• on the one hand, to install an insertion device for measuring the
pH, the oxidation reduction potential or the conductivity in a pipe
• and, on the other hand, to guarantee that the measurement sensor
is fully covered by the fluid.
6. TECHNICAL DATA
6.1. Conditions of use
Fluid
temperature
depends on the device inserted and the material
from which the S020 fitting is made. Refer to the
Operating Instructions for the device and to the
temperature/fluid pressure dependency curve in
Fig. 3. If the ranges are different, use the most res-
trictive range.
Ambient
temperature
depends on the device inserted into the S020.
Refer to the related Operating Instructions.
Pressure
class
depends on the device inserted and the material
from which the S020 fitting is made. Refer to the
Operating Instructions for the device and to the
temperature/fluid pressure dependency curve in
Fig. 3. If the pressure classes are different, take the
lowest value into account.
6.2. Dimensions
Refer to the related datasheet at www.burkert.com
6.3. Diameters available
The diameters available depend on the design of the S020 fitting.
Consult the technical data sheets for the S020 fittings and
the device inserted to determine the appropriate DN.

6.5. K factors
6.5.1. Terms of reference
The K factors have all been determined under the following terms
of reference: fluid = water, water and room temperatures of 20°C,
minimum upstream and downstream distances respected, appro-
priate pipe dimensions.
6.5.2. Calculation of K factors (in pulse/
litre) for saddles, fusion spigots,
welding sockets with radius or
screw-ons
The calculation does not apply to T fittings or welding
sockets for measuring devices with a clamp connection.
In addition to the terms of reference mentioned above, the K factors
for saddles, fusion spigots, welding sockets with radius and screw-
ons have been determined as a function of the external diameter
(Dmaterial) and the wall thickness (smaterial) of the pipe given in the
tables.
→When the dimensions of the pipe are slightly different from
dimensions D and s given in the tables, recalculate the K factor
using one of the following formulae:
These formulae can only be applied if the dimensions of the
pipe vary by +/-5% compared with the theoretical dimen-
sions given in the tables.

the pipe and smaterial = thickness of the
pipe)

6.5.3. K factors (in pulse/litre) for T fittings used with a 8041 or 8045 with a G2'' nut
We advise not to use a type 8041 or 8045 measuring device in an S020 fitting in brass as drifts in measurement may occur.
If the measuring device does not automatically convert the K factor, use the following conversion formulae before setting the para-
meters of the device:
• K factor in pulse/US gallon = K factor in pulse/litre x 3.785
• K factor in pulse/UK gallon = K factor in pulse/litre x 4.546
Two versions of the S020 in DN15 and DN20 exist, having different K factors.
Only version 2, identified by the "v2" marking, is available from March 2012. The "v2" marking can be found:
• on the bottom of the DN15 fitting in plastic:
V2
• on the side of the DN15 or DN20 fitting in metal:

6.5.8. K factors (in pulse/litre) for screw-ons
When the dimensions of your pipe are slightly different from dimensions D and s given in the table, recalculate the K factor using one
of the formulae in chap. 6.5.2.
If the measuring device does not automatically convert the K factor, use the following conversion formulae before setting the para-
meters of the device:
• K factor in pulse/US gallon = K factor in pulse/litre x 3.785
• K factor in pulse/UK gallon = K factor in pulse/litre x 4.546
