Flow Meter Installation Requirements
Before installing the flow meter, verify the installation site allows for these
considerations:
Warning!
Consult the flow meter name-
plate for specific flow meter
approvals before any hazard-
ous location installation.
1. Line pressure and temperature will not exceed the flow meter
rating.
2. The location meets the required minimum number of pipe di-
ameters upstream and downstream of the sensor head as illus-
trated Figure 2-1.
3. Safe and convenient access with adequate overhead clearance
for maintenance purposes.
4. Verify that the cable entry into the instrument meets the specific
standard required for hazardous area installations.
5. For remote installations, verify the supplied cable length is suf-
ficient to connect the flow meter sensor to the remote electron-
ics.
Also, before installation check your flow system for anomalies such as:
• leaks
• valves or restrictions in the flow path that could create disturbances in
the flow profile that might cause unexpected flow rate indications
