2.5 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.

2.6 Grounding the sensor
The sensor’s mounting plate must be grounded to earth.
If national standards are not in effect, follow these grounding guidelines:
• Use copper wire, 14 AWG (2,5 mm
2
) or larger wire size, for grounding.
• Keep all ground leads as short as possible, less than 1 Ω impedance.
• Connect ground leads directly to earth, or follow plant standards.
CAUTION
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.
