Mounting posture of electromagnetic flowmeter
The flowmeter can be installed vertically, horizontally, or at other angle. When installing, be sure to observe the following points.
q The measuring pipe should always fill with fluid which flows in the piping.
w The signal electrode should be at a level with the ground. And also signal electrode and ground electrode should always keep
How to connect the grounding cable contacting with measuring liquid.
Since the electromagnetic flowmeter is provided with a ground electrode, flow rate of liquid can be measured without an earth
ring. However, if stray potential exists in a pipeline, the potential in the pipeline may fluctuate.
In this case, the earth ring (option) of the same material as signal electrode and ground electrode should be mounted on the
upstream and downstream sides of the flowmeter to connect to the grounding terminal.
For liquid that contains attachments or deposits, take the liquid contacting ground from the optional earth rings and metallic pipe
(without lining).

contact with fluid. If the signal electrode or the ground electrode is upper position against the fluid, correct measurements
cannot be expected due to air bubbles on the fluid.
