EARTHING
The magmeter normally is uninfluenced by low levels of electrical noise. In
some applications it is necessary to connect the sensor to earth to eliminate
electrical noise.
The earthing can be done as following described:
• connecting the Ground Wire (black wire from the sensor body) to an External
Earthing passing through a cable gland.
• in case of plastic pipes, connecting the Ground Wire (black wire from the
sensor body) to metallic inserts ( such as flanged earthing rings ) into the
plastic pipe before and after the magmeter and then connecting them together
to an External Earthing. Fluid earths must be in direct contact with the fluid
near to the magmeter.
Note: If present, the shield from the output cable must be terminated only at
the remote instrument. Do not connect this shield at both ends.
