Electromagnetic flowmeter type MAG 3100 with PTFE or PFA liner
The sensor is equipped with a liner of PTFE
teflon. At delivery the sensor is mounted with
wooden blanks to hold the liner in place during
transportation and storage. These blanks
should remain on the sensor until installation.
Without the blanks the liner will creep back
towards its original shape and installation will
be more difficult to carry out.
The sensor should max. be left a few hours
without the blanks.
Immediately before installation, remove the
blanks.
The sensor is equipped with a liner of PFA. At
delivery the sensor is mounted with blanks to
protect the liner during transportation and
storage. These blanks should remain on the
sensor until installation.
Before installation, remove the blanks without
using sharp objects which can damage the
liner.
Electrically conductive piping
Potential equalization with an electrically con-
ductive pipe.
Use an earth straps on one side.
Non-conductive piping
Here an earthing flange is used, placed bet-
ween flowmeter and the adjacent pipe flange.
Earthing flange type E for PTFE.
For PFA flat rings must be used.
