What are the applications of Positive displacement flowmeter?

Many applications use Positive displacement flowmeters. Some of them are below.

Also suitable for measuring food processing with edible oils, honey, and molasses

Measurement of the direct flow of fluids or gasses in pipes.

Chemical industries to accurately calculate the flow of viscous fluids and other chemicals.

Positive displacement flowmeter uses volumetric flow measurement of petrochemicals, paints, and dyes.

Measurement of various chemicals for making batches in pharmaceutical laboratories.

In hydraulic testing, chemical dosing, pharmaceutical applications, and other related applications.

You can use it for the measurement of highly viscous and dirty fluid. But, you can also use clean and non-erosive fluid for accurate measurement in various applications such as inventory management of chemicals ranging from detergents to low concentrated acid solutions.

To monitor fuel consumption for generators in construction sites.

Although they are ideal for measuring viscous liquids, a Positive displacement flowmeter measures less viscous fluids like water, organic solvents, or alcohol.

What are the types of Positive displacement flowmeters?

  • Reciprocating or Oscillating Piston

This Positive displacement flowmeter uses a mechanically or magnetically operated piston for filling the cylinder with fluid.

  • Gear

Gear flowmeter depends on internal gears that rotate as the fluid passes through them. There are various types of gear based on their shape. For example, oval gear has two rotating oval gears that squeeze fluid through the meter. As the flow rate increases, so does the rotation of rotors. Helical gear has a spiral-shaped structure. Fluid enters the compartments in rotors which causes rotation.

  • Nutating Disk

A nutating disc flow meter has a round disc on a cylindrical chamber. The flow meter measures the number of times the chamber fills and empties fluid and consider as the widely used Positive displacement flowmeter. They are best for pressure ranges around 150-PSIG with an upper limit of 300 PSIG. The liquid enters the chamber using the disc, which divides the chamber into compartments.

  • Roots flowmeters

Roots flowmeters are somewhat similar to the oval gear flowmeter. It consists of two-lobed impellers which rotate in opposite directions. You can measure fluid measurement by measuring the rotation speed; the maximum range of viscosity for this PD flowmeter is 5000 centipoise

What are the advantages of a Positive displacement flowmeter?

  • Positive displacement flowmeters are very accurate, reliable, and have high turndown.
  • They measure viscous and corrosive fluids and require no straight runs of pipe.
  • Positive displacement flowmeter uses custody transfer of oil and fluids, in-home natural gas, and metering.
  • Positive displacement flowmeters with internal wiping seals have the highest differential pressure.
  • They are suitable for fluids with high viscosity.
  • They require little or no maintenance and have a long life
