1.03 DEFINITIONS
A. Definitions used in this specification and equipment submittals for terms related to rotor-dynamic pumps shall be in accordance with HI 9.6.8, Appendix A, as clarified below.

B. These definitions shall be applied to equipment other than pumps, unless otherwise specified in technical sections.

C. Rotordynamic Analysis Level:

1. The level of detail required for rotordynamic analysis is indicated in the technical sections schedules as None (no analysis required), Analysis Level 1, Analysis Level 2, or Analysis Level 3, which correlate to increasing levels of required detailed equipment design analysis. Analysis Levels 1, 2 and 3 are based on HI 9.6.8.

2. Where these specifications differ from HI the more stringent shall apply.

D. Resonant Frequency:

1. The frequency of a periodic excitation force that is close to the natural frequencies of an object. Also known as critical frequency, critical speed, or resonant speed.

2. An undamped resonant frequency within the separation margin is always considered harmful under Level 1 analysis.

3. A resonant frequency that occurs within a separation margin of 15 percent above or below the operating speed range and has a log decrement greater than +0.3 is considered harmful under Level 2 and Level 3 analysis.

E. Separation margin:

1. The span of operating speeds within which interference between excitation orders and resonant frequencies indicate the possibility of harmful vibrations.

2. The separation margin for a specific application extends 15 percent above and 15 percent below the span of operating speed required for the specified performance conditions.

1.04 ADMINISTRATIVE REQUIREMENTS
A. Roof coordination:

1. Show roof penetrations for mechanical equipment on roof drawing submittal and include mechanical equipment information:
a. Type.
b. Size.
c. Location.
d. Configuration of penetration and the surround.
e. Weight.
f. Anchoring and support details.

b. Not be cast as part of the maincase.
c. All piston assemblies interchangeable in all measuring chamber assemblies of the same size.

7. Magnetic coupling:
a. The motion of the piston will be transmitted to the sealed register through the use of a magnetic coupling.

8. Strainers:
a. All meters, 2 inch or greater, must be provided with a corrosion resistant strainer, with an effective straining area at least twice the bore diameter which can be easily removed from the meter without the meter itself being disconnected from the pipeline.

9. Change gears:
a. Change gears will not be allowed to calibrate the meter.

10. Provide identical and completely interchangeable registers of a particular registration and meter size. Accuracy and head loss tests:
a. Meters meet or exceed current AWWA C700, current revision, test flows, head loss and accuracy standards.

11. Pressure capability:
a. Meters operate up to a working pressure of 150 pounds per square inch, without leakage or damage to any parts.
b. Meter accuracy not affected when operating at 150 pounds per square inch due to possible distortion.

12. Meter accuracy not affected by variations in pressure up to 150 pounds per square inch. Register and remotes:
a. Permanently and hermetically sealed register and firmly attached to meter case.
1) Provide a security seal to prevent easy removal and tampering. 2) The register must be an encoder type and must be readily adaptable to an outside wall or pit mount inductive reading pad, a walk-by or drive-by short range radio or an automatic fixed network radio meter reading system.

B. 2 inch thru 6 inch compound meters:

1. Scope:
a. The meters in accordance with AWWA C702, as most recently revised, except as modified in this Section.

2. Type:
a. Single or dual register type meters.
1) Single register type:
a) Totalize the output from 2 interacting measuring chambers. (1) One turbine type for measuring high flows.
(2) One displacement chamber of the oscillating piston type for measuring low flows.
b) Direct flows through the chambers using an automatic valve mechanism so as to have them function within their normal designed limits.
(1) Flows first pass through the turbine chamber prior to passing through the oscillating piston measuring chamber so as to ensure continuous registration during low flow to high flow measurement.

3. Size:
a. Determine size of meter by the nominal size of the opening of the inlet and outlet flanges of the meter.

4. Length:
a. Maximum overall length of the unit is the face-to-face dimension as listed below:

Size of Meter Length
2 inch 17 inches
3 inch 17 inches
4 inch 20 inches
6 inch 24 inches

5. Cases:
a. Construct maincases of Water Works Bronze.
b. Repaired casings are not acceptable.
1) Construct the turbine and oscillating piston measuring chambers as separate units.
2) Operation of an external valve cannot inhibit the oscillating piston measuring chamber operation.
3) Access both measuring chambers without disturbing the maincase as set in the pipeline.
4) All sizes of meters include flanged ends.
c. Provide drain plugs for ease of removing water or other debris from the bottom of the maincase.
d. Provide a test port of adequate size must be accessible from the top so as to allow testing in pit settings and confined areas.
e. Provide a threaded port outlet with a bronze plug.
f. Provide raised characters cast on the outer case indicating the size and direction of water flow through the meter.

6. Strainers:
a. External body strainers may be specified as part of the meter assembly package.
1) When specified, construct external body strainers of Water Works Bronze similar to that of the compound meter body.
2) Provide strainer with a removable cover plate for inspection and debris removal.
3) Provide strainer screen that is externally accessible and easily removable without disturbing the pipeline setting of the meter assembly package.

7. External fasteners:
a. Provide external fasteners on the meter made of stainless steel or nonferrous material.

8. Connections:
a. Flanges on 2 inch size meters:
b. Oval faced and drilled on the horizontal axis with a bolt circle diameter of 4-1/2 inches.
1) Thickness conforming to Class 150 bronze round flange requirements.
c. Flanges for 3 inch, 4 inch, and 6 inch size meters: Class 150 bronze round type, flat faced, in accordance with ASME B16.24 for specified diameter.
d. Companion flanges, if required with the meters:
e. Consist of 1 standard cast iron flange, tapped with American Standard internal taper pipe threads, of the same nominal size as the meter, and 1 flanged coupling adaptor.
1) Provide type and outside diameter of connecting pipe for appropriate gasket sizing.

9. Provide stainless steel or non-corrosive bolts, nuts, and gaskets for connection to the meter assembly.

10. Register box:
a. Construct register box of the same material as the maincase. b. Mount and orient the register box, which encloses the register, to allow reading in any position.
