Which meter type is composed of two meters that can read small and large flows?

The compound meter is specifically designed to measure varying flow rates, making it suitable for applications that experience both low and high flow scenarios. It consists of two distinct measuring components: a smaller meter that accurately reads low flows and a larger meter that handles high flows. This dual functionality allows for precise measurement across a wide range of flow conditions, providing operational efficiency and accuracy.

In situations where flow rates fluctuate significantly, such as in industrial processes or certain water distribution systems, compound meters ensure that both small and large flows are accounted for correctly. This feature is critical for billing purposes, system monitoring, and hydraulic assessments. By choosing a compound meter, water utilities can effectively manage and measure consumption without compromises on accuracy.

Other types of meters, such as single jet meters, magnetic meters, and ultrasonic meters, may serve specific purposes but do not have the dual measuring capability that compound meters provide. Single jet meters are generally effective at low flow rates, while magnetic and ultrasonic meters can offer advantages in specific installation scenarios but are not built for the same broad flow range measured by compound meters.
