Section 16915 Flow Monitoring
1. General
1.1 Description
.1 For all instrumentation, the Equipment Supplier shall furnish all labour, materials,
components, and programming, and shall provide all design, assembly, and start-up
services required to provide a complete and workable system.
.2 Provide assistance to the Owner and Engineer for the testing and commissioning of the
instrumentation.
1.2 Operation and Maintenance Manuals
.1 Provided for insertion within the general project operation and maintenance manuals shall
be at least four copies of original equipment manufacturer printed manuals. These shall
include at a minimum:
Full User Manual
Installation Instructions
Full list of Parameters/Programming Manual
Troubleshooting/Maintenance Manual
.2 A complete list of all parameters programmed into each instrument at the end of
commissioning shall be provided for insertion within the general project operation and
maintenance manuals. These lists shall be clearly sorted by instrument tag number.
1.3 Submittals
.1 Submit shop drawings for all flowmeters and flow switches providing full details on make,
pipe size, measuring range, instrumentation tag number, full model number (with options
clearly indicated), dimensions, wiring and power requirements, digital communication
addresses (Modbus, Profibus, Foundation Fieldbus, etc.), and all installation accessories
for each flowmeter.
.2 Shop drawing submittals for flowmeters shall be clearly identified by tag number. For
example: “50mm Flowmeter A - FIT-123” and “150mm Flowmeter B – FIT-456”. Like
flowmeters can be combined for example: “100mm Flowmeter C – FIT-123/FIT-456/FIT-
789”.
