Operating instructions for KME flow meter for compressed air and gases
3.5 Installation of the gauge mounting block
The gauge mounting block is symmetrical and can be installed in the pipeline irrespective of the
flow direction.
•
All connections must be properly sealed and checked for tightness.
•
The thread seals shall not impact on the cross section of the pipe or of the block.
3.5.1 Operating the pipeline without transmitter
To operate the pipeline without the transmitter unit, the opening of gauge mounting block which
accommodates the sensing head can be closed using the sealing plug included in the scope of
supply (fig. 5). The sealing plug has a Tuflok® coating (http://www.bossard.com ) and does not
require any additional seal.
Mount the sealing plug with a torque of min. 28 Nm.
Under normal operation with transmitter installed, the sealing plug shall be placed for safe keep-
ing into the opening at the side of the gauge mounting block (fig.6).

3.6 Mounting the transmitter unit into the gauge mounting block
Depressurize the pipeline before mounting or removing the transmitter
unit.
In case the gauge mounting block has been operated without transmitter, remove the sealing
plug with a WAF 13 spanner.
Remove the protective cap from the sensing head (fig. 7) and insert carefully the sensing head of
the transmitter into the gauge mounting block.
