(1) A water meter includes at least a measurement transducer, a calculator (including adjustment or correction devices, if present) and an indicating device. These three devices may be in different housings. (2) A water meter may be a combination meter comprising one large meter, one small meter and a changeover device that, depending on the magnitude of the flowrate passing through the meter, automatically directs the flow through either the small or large meter or both. Meter reading is obtained from two independent totalizers or one totalizer, which adds up the values from both water meters.
