Observe the following items when routing cables:
• The signal and magnet coil cable carries a voltage signal of only a few millivolts and
therefore must be routed the shortest distance possible. The maximum permissible signal
cable length is 50 m or 200 m, if the flowmeter sensor is equipped with a preamplifier.
• Avoid routing the cable in the vicinity of electrical equipment or switching elements that can
create stray fields, switching pulses and induction. If this is not possible, run the
signal/magnet coil cable through a metal pipe and connect this to the station ground.
• All leads must be shielded and connected to station ground.
• Do not run the signal cable and the magnet coil cable over junction boxes or terminal blocks.
• To shield against magnetic interspersion, the cable contains outer shielding that is attached
to the SE clamp.
• Make sure during installation that the cable
is provided with a water trap (1). For vertical
installation, align the cable glands pointing
downward.
