Which of the following describes an orifice plate, insertion type meter?

• A. A positive displacement meter with an oscillating disc
• B. A velocity meter with a propeller
• C. A meter that consists of a thin plate with a circular hole, which is installed between flanges to determine the flow rate
• D. A metering device that consists of two meters, intended to measure a large range of flow

Answer: (C)

The description of an orifice plate, insertion type meter is accurately captured by stating that it consists of a thin plate with a circular hole, which is installed between flanges to determine the flow rate. This type of meter operates on the principle of differential pressure. As fluid flows through the orifice (the circular hole), it causes a change in pressure that can be measured and used to infer the flow rate. The installation between flanges allows for integration into existing piping systems, making it a versatile option for various applications in water distribution. Other types of meters, such as positive displacement meters or those with propellers, operate on different measurement principles and are not characterized by the installation of a flat plate with a hole. By understanding the specific construction and functioning of the orifice plate, one can effectively apply this knowledge in practical scenarios involving flow measurement in water distribution systems.
