Product Description
A PD meter, or positive displacement meter, is a type of flow meter that measures the volume of fluid passing through it by trapping and measuring discrete volumes. It works by using internal components like gears or rotors to create a chamber that fills and empties with the fluid, with the number of rotations or movements of these components directly proportional to the flow rate. These meters are known for their high accuracy and good repeatability, making them suitable for various applications, including household water meters and industrial processes.
