500.2 Types of meters.
Service meters covered by this Part in use for measuring water delivered to consumers are divided into four general classes, as follows: displacement, current, compound, and fire-service.
(a) Displacement meters.
Displacement meters are known by the motion of the piston, as reciprocating, rotary, oscillating, and nutating disc meters. These meters are positive in action and displace or carry over a fixed quantity for each stroke or revolution of the piston or disc.
(b) Current meters.
Current meters are nonpositive in action, but record the flow by the number of revolutions of a water wheel or propeller, which is set in motion by the force of the flowing water coming in contact with the wheel or propeller blades.
(c) Compound meters.
Compound meters consist of a combination of a mainline meter of the current or displacement type for measuring large flows and a small by-pass meter of the displacement type for measuring small flows, together with an automatic valve mechanism for diverting the small flows through the by-pass meter.
(d) Fire-service meters.
Fire-service meters are compound meters consisting of a main-line meter of the proportional type for measuring large flows and a small by-pass meter of the displacement type for measuring small flows together with an automatic valve mechanism for diverting the small flows through the by-pass meter. The combination is designed to afford a clear passage through the meter when the valve is raised from its seat.
