Mounting the sensor
Use your common practices to minimize torque and bending load on process connections. Figure 2-1
illustrates how to mount the sensor.

Grounding the sensor
The sensor's mounting plate must be grounded to earth.
Improper grounding could cause measurement error.
To reduce the risk of measurement error:
•
Ground the flowmeter to earth, or follow ground network requirements for the
facility.
•
For hazardous area installations in Europe, refer to standard EN 60079-14 if
national standards do not apply.
If national standards are not in effect, follow these grounding guidelines:
•
Use copper wire, 14 AWG (2,5 mm
Keep all ground leads as short as possible, less than 1 Ω impedance.
•
•
Connect ground leads directly to earth, or follow plant standards.
