Which type of meter is most commonly used for customer water services?

• A. Positive displacement meter
• B. Magnetic flow meter
• C. Ultrasonic meter
• D. Diaphragm meter

Answer: (A)

The positive displacement meter is the most commonly used type of meter for customer water services due to its simplicity, reliability, and accuracy at low flow rates. This design involves a mechanism that directly measures the volume of water flowing through the meter by effectively "displacing" a set volume with each cycle. As water moves through the meter, it fills and empties a series of chambers or cylinders, which can be easily read. This type of meter is particularly effective for residential or small commercial settings where flow rates are variable but generally lower compared to industrial applications. Moreover, positive displacement meters remain reliable over time, providing accurate readings even as water demand fluctuates. The other options, while viable in specific applications, typically cater to different needs. Magnetic flow meters, for example, are often used for larger pipelines or industries due to their ability to measure the flow of conductive fluids without moving parts, which can make them more suitable in situations where maintenance and wear are concerns. Ultrasonic meters measure flow by sending sound waves through the fluid, which can introduce complexities in installation and calibration, making them less common for standard residential applications. Diaphragm meters are used in some specific settings and applications, particularly in gas measurement, but they are not the standard choice for general
