Cone flow meters are becoming one of the most reliable and accurate flow measurement solutions for industries worldwide.
Designed with a flow-conditioning cone, these differential pressure (DP) flow meters improve accuracy, minimize turbulence, and provide consistent performance, even in harsh operating conditions.
In this guide, we’ll cover everything you need to know about cone flow meters, their working principle, key components, advantages, disadvantages, and industrial applications.
The cone, placed in the center of the pipe, distributes fluid evenly, reduces turbulence, and helps measure the flow rate accurately.
The pipe body is typically made of stainless steel or titanium, ensuring durability under high pressure and extreme temperatures.
These convert pressure readings into electrical signals for monitoring. Modern DP transmitters are integrated with industrial automation systems, allowing real-time data tracking and remote access.
Two taps measure pressure, one before and one after the cone.
This setup eliminates turbulence effects, resulting in stable and precise flow measurement.
Flanges secure the cone inside the pipe and connect the flow meter with the piping system, ensuring it remains stable under extreme flow conditions.
Sensors monitor temperature and pressure changes to account for variations in fluid viscosity and density, which directly affect flow accuracy.
Burak's Cone Flow Meters are engineered with precision components that ensure durability, reliability, and unmatched accuracy.
Here’s how a cone flow meter works step by step:
Fluid enters and hits the centrally placed cone, which spreads the flow evenly. Unlike other flow meters, cone meters don’t require long straight pipe runs for accurate measurement.
As fluid passes through the narrow section around the cone, velocity increases and pressure decreases (Bernoulli’s principle). This creates a measurable differential pressure.
A DP transmitter measures this difference to determine the flow rate.
Using Bernoulli’s principle and flow equations, the pressure difference is converted into an accurate flow rate calculation, considering temperature, pressure, and fluid type.
Oil & Gas Industry: In the oil industry, it is used for measuring crude oil, natural gas, and multiphase flows in pipelines.
Chemical & Petrochemical Industry: Here, in the chemical industry, it measures the flow rate of aggressive, corrosive, and viscous chemicals.
Power Generation: For power generation, it is essential to measure the steam, cooling water, and fuel flow in power plants.
Water & Wastewater Treatment: In water and wastewater treatment, it is used to measure raw water intake, treated water distribution, and wastewater flow.
Aerospace & aviation: Cone flow meters are also used in rocket engines to test fuel measurement.
Food & Beverage Industry: Here, in the Food and beverage industry, it measures the flow of liquids like milk, juices, syrups, and soft drinks in processing plants.
Pharmaceutical & Biotechnology Industry: In pharmaceuticals, it is for precisely measuring the flow of liquid chemicals and gases in drug manufacturing.
Discover the different types of flow meters and how they work.

A cone flow meter is a differential pressure (DP) flow meter that uses a cone-shaped element to condition the fluid, reduce turbulence, and measure flow accurately.
It works by placing a cone inside the flow path. As fluid passes around the cone, a pressure drop occurs. The differential pressure is measured and converted into flow rate.
Cone flow meters are used in oil & gas, chemical plants, power generation, water treatment, aerospace, food & beverage, and pharmaceutical industries.
They offer high accuracy, no need for long straight pipes, durability in harsh conditions, minimal maintenance, and compatibility with liquids, gases, and steam.
Cone flow meters are more expensive, less effective at very low flow rates, and have limited availability of spare parts compared to traditional meters.
Burak provides precision-engineered cone flow meters that ensure long-term accuracy, durability, and efficiency—customized for your industry’s needs.
