Current meters are also known as:

Current meters are specifically designed to measure the velocity of water flow in open channels or in pipes. They operate by evaluating the speed of water moving past the meter, which is crucial for various applications, such as hydrology and wastewater management. By accurately measuring the velocity, current meters can help determine flow rates and are critical tools in water resource management and environmental assessments.

While other types of meters serve different purposes—flow meters, for instance, can measure the total volume of liquid moving through a system rather than just its velocity—current meters provide specific insights into the flow characteristics by focusing on the speed component. Pressure meters, on the other hand, measure force per area and level meters track the height of liquids in containers or bodies of water. These distinctions highlight the unique role of current meters as velocity measurement instruments in the study and management of fluid dynamics.
