NB. See manual for precise connection details.
l The flow meter body should be grounded.
l Shielded cables are recommended.
3 l The housing of the transducer is grounded and the cable
shield should connect to this case. Over short distances
the cable shield should be grounded at the receiving end
2
but over longer distances and problematic installations
the shield can be left open circuit or grounded via a
capacitor (typically 100nf).
NB. Ground loop currents can cause inaccurate and erratic
readings.
