user/qualified personnel before installation, initiation and maintenance
Regional and national regulations respectively, have to be observed in addition to this instruction
manual if necessary.
This instruction manual has to be available at any time at the operation site of the Type 8007.
Ensure that the Type 8007 operates within the permissible and listed limits on the nameplate.
Otherwise there is a risk to human and material, and it may occur functional and operational
disturbances
In case of any obscurities or questions with regard to this manual or the instrument please contact
CS Instruments GmbH..
Warning!
Risk of injury in case of inadequate qualification!
Improper handling can result in significant personal injury and damage.

3.1 Intended Use
The instrument described in this manual is exclusively to use for measuring the thermal mass flow of
gases. At the same time, the gas temperature is measured too.
The Type 8007 can be configured for measuring a predetermined range of pure gases or of
gas mixtures.
Improper or incorrect use the operational reliability will be canceled. The manufacturer is not liable for
any damage resulting by improper or incorrect use.
3.2 Installation and commissioning
Installation, electrical installation, commissioning, operation and maintenance of the device
must only be carried by qualified personnel, which were authorized by the plant operator.
The personnel must read the operating instructions and understand and follow their
instructions.
If carrying out welding work on the pipeline the grounding of the welding unit is not allowed to
be done over the Type 8007 itself.
The installer has to ensure that the Type 8007 is connected according to the electrical
connection diagrams properly. The sensor must be grounded, unless special protective
measures have been taken (e.g. galvanically isolated power supply)
The existing/ applicable national regulations governing opening and repair of the device have
to be applied.
The device fulfills the general safety requirements in accordance with EN 61010-1,
the EMC requirements of IEC / EN 61326 and NAMUR recommendation NE 43.

4.2 Measuring range flow Type 8007
The flow-/consumption sensor Type 8007 is available in 4 different versions:
Low Speed max. measuring range of 50 m/s
Standard max. measuring range of 92,7 m/s
Extended max. measuring range of 185.0 m/s
Maximum max. measuring range of 224 m/s
The sensors are programmed to pipe inner diameter of 53,1 mm this corresponds to analogue output
4- 20 mA of:
Measuring range Analogoue output Scaling
Low Speed 0… 323,6 m³/h 4mA = 0 m³h, 20mA = 323,6 m³/h
Standard 0 … 600 m³/h 4mA = 0 m³h, 20mA = 600 m³/h
Extended 0 ... 1197,59 m³/h 4mA = 0 m³h, 20mA = 1197,59 m³/h
Maximum 0 … 1450,06 m³/h 4mA = 0 m³h, 20mA = 1450,06 m³/h
In case of use in other inner pipe diameter the diameter, using the display version, the diameter has
to be set first.
The corresponding scale values for the respective version could be found in sections 4.2.1 to 4.2.4.
Example:
Pipe 1“, Inner diameter 25mm Measuring range Analogoue output Scaling
Low Speed 0 … 65,9 m³/h 4mA = 0 m³h, 20mA = 65,9 m³/h
Standard 0 … 122,2 m³/h 4mA = 0 m³h, 20mA = 122,2 m³/h
Extended 0 ... 243,88 m³/h 4mA = 0 m³h, 20mA = 243,88 m³/h
Maximum 0 … 295,30 m³/h 4mA = 0 m³h, 20mA = 295,30 m³/h
For changing the inner pipe diameter and adjusting the 4…20mA scaling, please refer to chapter
“Operation”.

Installation
Type 8007 English V1.16 Page 20 of 43
6 Installation
6.1 Pipe/tube requirements
Correctly sized gaskets
Correct aligned flanges and gaskets
Diameter mismatch at the pipe junctions should be avoided but must be less than 1mm. For
further information see ISO 14511
Ensure clean pipes after installation
6.2 Inlet / outlet runs
The principle of thermal Mass flow measurement is very sensitive against disturbances. Therefore, it is
necessary to ensure the recommended inlet and outlet runs.

The values represent the min.lenghts. In case the min. inlet / outlet runs could not be ensured, it must
be expected to get increased or significant deviations of the measurement values.
