Know How a Positive Displacement Flow Meter Works

When it comes to measuring the overall volumetric flow rates for liquid matter, nothing works better than flow meters that are used in varied applications pertaining to different operational fields. Industrial flow meters present in the market are used for several high-end applications, and each of them possesses different advantages, functional values, features, mechanisms, and specifications.

What is a Positive Displacement Flow Meter?

To define the device, what is Positive Displacement flow meter (PD) ? – A mechanical meter that is best used for non-corrosive and clean mediums. Being capable of measuring an extensive range of fluids that include even the ones with high viscosities, this flow meter comes with several advantages.

Also known as workhorses in flow measurement applications, this flow rate measurement device measures the flow rate of a liquid substance by letting it to move through a system in installments. When utilized for industrial applications, PD flow meters are known for their capabilities to measure multiple intricate and critical liquid flow rates with accuracy and ease.

Nevertheless, the newly-discovered technical advancements in the field of flow meters are posing a challenge to the existence of positive displacement flow meters. However, PD flow meters still hold their value for certain specific applications. For instance, these devices effectively determine the amount of gas or water used in varied commercial offices, residences, buildings, and industrial plants.

How does it Work?

The PD flow meter is the only flow meter kind that directly measures the volume of the volume passing through the meters. This action is achieved by placing a rotating or oscillating object in the path of the fluid that helps to measure the exact quantity of the displacing fluid.As the most popular nutating disc type flow meter in terms of technology, a PD flow meter consistently entangles the fluid in the system in order tomeasure its total flow. The rotating parts help to entrap the liquid by using moving seals between one another and between the flow meter. The speed of the rotating parts increase with the increased flow of fluid through the system.Also, the meter is also fitted with a transmitter, which operates the signal to assess the liquid flow.

While selecting an apt PD flow meter, customers are expected to know about the range of applications that would determine the apt type of device to be bought and applied.
