Section 9: I&C AND WATER METERS

MIL-HDBK-1164

9.

9.1

Overview of Section. This section contains information on primary

instrumentation (sensors), secondary instrumentation (transmitters and recorders), and

control systems as well as supervisory control and data acquisition (SCADA) systems,

which are relatively new tools for controlling and monitoring water treatment systems.

Special attention is given to O&M of water meters and other flow measuring devices

such as weirs and flumes.

9.2

References. Detailed information on instrumentation and control (I&C)

and water meters is presented in several publications. The list below identifies useful

publications, along with the paragraph number corresponding to each document's

listing in Section 2, Applicable Documents. Subsequent references to these

publications are given by paragraph number alone.

I&C. The term "instrumentation," as used in the water works industry,

refers to a very wide range of equipment used for observation, measurement, and

control. Equipment types range from simple, mechanical, direct-reading meters and

gages to complex electronic, automatic monitoring/control systems. All I&C systems
