PD Flowmeter

PD flowmeter, or a positive displacement flowmeter, is a type of flowmeter that measures the flow rate of a fluid by precisely measuring the volume of fluid passing through the flowmeter.

The operation of a PD flowmeter is based on the principle that a fixed volume of fluid is displaced by each revolution of the meter's internal components. These internal components may be gears, pistons, or some other type of mechanism that rotates or reciprocates. As the fluid passes through the flowmeter, it causes these internal components to move, and the number of rotations or reciprocations is used to determine the volume of fluid that has passed through the flowmeter.

PD flowmeters are commonly used in industries such as oil and gas, food and beverage, and chemical processing, where precise measurement of fluid flow rates is critical. They are generally considered to be highly accurate and reliable, and they can measure a wide range of fluid viscosities and temperatures.
