5 Installation prerequisites
Topics covered in this chapter:
• Pre-start checks
• Torque information
• Tools required for LME disassembly/assembly
5.1 Pre-start checks
1. Inspect all electrical connections to ensure compliance to electrical codes and safety
regulations.
2. Inspect all bolts used to secure the turbine meter in line to ensure that correct
mounting procedures have been followed and that flange connections are leak-free.
3. Evaluate the system setup to ensure that all components are in the correct sequence
for accurate product measurement: isolation valve, strainer, flow straightener,
turbine meter, downstream section, control valve, etc.
4. Ensure that the supply voltage to the preamplifier is within the 10-30 VDC range.
5.2 Torque information
Important
Ensure that piping or other attachments connected to the turbine meter are not under stress.
