[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS:

A. General:

1\. Meter casing shall be bronze unless otherwise specified.

2\. Maximum operating pressure is 150 psig.

3\. Meter shall register in either cubic feet or U.S. gallons.

B. Disc Water Meters:

1\. \[Frost bottom\] \[Split case\] magnetic‑drive,
positive‑displacement, cold water meter of the nutating disc type.

2\. One‑piece, conical‑shaped, metal‑reinforced nutating disc piston of
vulcanized hard rubber which rotates a permanent ceramic magnet.

3\. Register box and lid constructed of cast bronze.

4\. Registers accessible so that they can be reset by utility personnel.
Registers available with \[center sweep hand\] \[straight reading\]
\[round reading\] indicator.

5\. Meter to be equipped with a strainer having an effective straining
area more than double that of the inlet of the meter.

C. Compound Meters:

1\. Single, all‑bronze case meter with \[magnetic drive on mainline and
bypass\] \[mechanical drive with hermetically sealed register\].

2\. Bypass disc piston shall be one‑piece, vulcanized hard rubber with
metallic reinforcement; stainless‑steel spindle.

3\. Bypass measuring chamber shall be three‑piece bronze consisting of a
chamber ring and removable top and bottom plates secured with stainless‑
steel screws. The stainless‑steel diaphragm is held in place by slots in
the chamber ring and top plate.

4\. Lever valve weight, swing arm, and bronze seat provide positive seal
for accurate bypass meter registration.

5\. Bypass shutoff valve shall permit maintenance of bypass section
without shutting down service, while mainline meter continues to
operate.

6\. Separate mainline and bypass registers shall provide direct
indication of relative meter usage at high and low flows. A test outlet
shall be provided to permit testing and recalibration of both mainline
and bypass meters.

7\. Parts and assemblies shall be accessible and removed or assembled
without removing the meter from the line.

D. Turbine Meter:

1\. General: The turbine water meter shall have a range of \[[
]{.underline} ‑ [ ]{.underline}\] gal/min with an accuracy of 100%
[+]{.underline} \[[ ]{.underline}%\] of actual input. Pressure loss
through the meter will be \[[ ]{.underline}\] psi at \[[ ]{.underline}\]
gal/min. Maximum operating pressure shall be 175 psig, with a
temperature range of 32 degrees F ‑ 130 degrees F. Register indication
shall be \[100,000,000\] \[1,000,000,000\] gal with \[100\] \[1,000\]
gal sweep hand revolution, or \[10,000,000\] \[100,000,000\] ft^3^ with
a \[10\] \[100\] ft^3^ sweep hand revolution.

2\. Meter Construction: Turbine shall have four basic parts: Top case,
bottom case, inlet hub, and rotor. The case shall be bronze, and the
inlet hub shall be constructed of synthetic polymer. Register and change
gears shall be accessible for meter recalibration. Inlet hub and rotor
shall be removable for maintenance.

3\. Rotor: The polypropylene rotor is the only moving part exposed to
the water. The rotor shall float in water, thereby exerting minimum wear
on the bearings. Rotor blades shall be designed for maximum efficiency
at low flows, while fluid shear is controlled so as to maintain uniform
registration at higher flows.

4\. Magnetic Drive: A ceramic magnet shall be mounted on the face of the
rotor so as the rotor turns, the one‑piece magnet‑worm gear located
inside a hermetically sealed section engages the train‑gear spindle.

[PART 3: EXECUTION]{.underline}

3.1 INSTALLATION:

A. Requirements:

1\. Inlet and outlet gate valve shall have a bypass line to permit
onsite maintenance.

2\. Straight pipe diameter shall be installed ahead of meter as
recommended by the manufacturer.

3\. Install a test tee in line past the meter.

4\. Provide flanged connections for installations unless otherwise
specified.

5\. Adapters and fittings are required for a complete installation as
recommended by the manufacturer.
