The voltage induced is proportional to the flow velocity and is supplied to the amplifier by means of two measuring electrodes. The flow volume is calculated by means of the pipe cross-sectional area.

Most Promag sensors have a built-in reference electrode as standard which guarantees the necessary connection. As a result, the use of ground disks or other measures is generally not ! When installing in metallic pipes, we recommend you connect the ground terminal of the transmitter housing with the piping.

9 Also, observe local grounding equalization via the ground terminal of the transmitterCaution! For sensors without reference electrodes or without metallic process connections, potential equalization must be carried out as described in the following special cases. These special measures apply especially where normal grounding cannot be guaranteed or excessively strong equalizing currents are , not grounded pipingTo prevent electrical noise disturbing influences on the measurement, we recommend both sensor flanges be connected to the pipe flange via a ground cable and grounded. The transmitter or sensor terminal compartment must be set to ground potential via the ground terminal provided (see the diagram below).Note! The ground cable required for the flange-to-flange connection can be ordered separately from Endress+Hauser as an accessory : DN 300: the ground cable is mounted directly on the conductive flange coating with the flange screws.

10 DN 350: the ground cable is mounted directly on the transportation metal equalization in the case of equalization currents in metallic, not grounded piping9 AWG (6 mm Cu)Pip sizePip size12 (DN 300) 14 (DN 350) Proline Promag 10 W8 Endress + HauserPlastic pipelines or pipelines with insulating liningNormally, potential equalization takes place via the reference electrodes in the measuring tube. However, in exceptional circumstances, large equalizing currents can flow via the reference electrodes due to the grounding concept of a plant. This can destroy the sensor due to the electrochemical reduction of the electrodes, for example. In such instances, in the case of fiberglass or PVC pipelines, we recommend the additional use of ground disks for potential ! Risk of damage by electrochemical corrosion. Please note the electrochemical series if ground disks and measuring electrodes are made of different material.
