More Than Mass: Deriving Concentration, Brix, and API Gravity with Coriolis Data

Image
When most engineers think of Coriolis flow meters, the first thing that comes to mind is precise mass flow measurement. But these advanced instruments offer far more than just flow data. Thanks to their ability to simultaneously measure mass flow, density, and temperature, Coriolis meters unlock powerful secondary calculations—like concentration, Brix, and API gravity—that are critical in industries ranging from food and beverage to oil and gas . This multivariable capability transforms a single device into a full process analytics hub. Instead of installing multiple sensors for flow, density, and temperature, operators can rely on one robust instrument. And because Coriolis meters measure directly—without needing external compensation for pressure or temperature—the derived values are highly reliable . One of the most valuable applications is determining fluid concentration. In the food and beverage industry, this means measuring sugar content using the Brix scale. For example, ...

Ultrasonic vs. Differential Pressure: A Comparative Guide to Gas Flow Meter Technologies

Image
When it comes to measuring gas flow, two of the most widely used technologies are ultrasonic and differential pressure (DP) flow meters. Each has its strengths and weaknesses, making them suitable for different industrial applications. Understanding how they work and where they excel can help you choose the right solution for your operation. Differential pressure flow meters operate by measuring the pressure drop across a constriction in the flow path, such as an orifice plate, venturi, or pitot tube. This pressure difference is proportional to the square of the flow rate. One popular variant is the pitot tube flow meter , which is ideal for measuring gas velocity in ducts or pipes and is often used in HVAC and industrial air systems . These meters are cost-effective and well-understood, making them a go-to option for many standard applications. You can learn more about how they function by visiting this guide on pitot tube flow meter and check out a specific model like the pitot tu...

Mastering Gas Flow Measurement: The Role of Transit Time and Doppler Ultrasonic Principles

Image
Ultrasonic flowmeters have become essential tools in modern flow measurement, especially when dealing with gases and clean liquids. These devices use sound waves to determine the velocity of a fluid, offering non-invasive and highly accurate readings. Two main types dominate the field: transit time and Doppler ultrasonic flowmeters. Each operates on distinct physical principles, making them suitable for different applications. Understanding how they work helps engineers and technicians choose the right solution for their needs . Transit time ultrasonic flowmeters are widely used for measuring gas and vapor flow, as well as clean liquids like water or chemicals. They function by sending ultrasonic signals in both upstream and downstream directions through the pipe. When there's no flow, the travel time is the same in both directions. But when fluid moves, the downstream signal travels faster while the upstream one slows down. The difference in transit times is directly proportiona...

Choosing the Right Gas Flow Meter: A Comparative Guide to Ultrasonic, Thermal, and Differential Pressure Technologies

Image
When selecting a gas flow meter, the choice often comes down to three dominant technologies: ultrasonic, thermal, and differential pressure. Each has its strengths and ideal use cases. Understanding how they work and where they perform best can save time, reduce maintenance costs, and improve measurement accuracy across industrial, commercial, and scientific applications. Ultrasonic flow meters use sound waves to determine the velocity of a gas. They are non-intrusive, meaning they don't require any moving parts or direct contact with the flow stream. This makes them highly reliable and low maintenance. They are especially effective in large-diameter pipelines and applications where minimal pressure drop is critical. Their accuracy remains high even under varying flow conditions, making them suitable for custody transfer and natural gas monitoring . Thermal mass flow meters, on the other hand, measure flow based on the heat transfer between a heated surface and the flowing gas....

Clamp-On or Transit-Time? A Guide to Selecting the Right Ultrasonic Flow Meter

Image
When it comes to non-invasive and highly reliable flow measurement, ultrasonic flow meters have become a go-to solution across industries ranging from water treatment to oil and gas. However, with multiple types available—especially clamp-on and transit-time designs—choosing the right one can be challenging. Understanding the differences, advantages, and limitations of each type is essential for optimizing performance, accuracy, and cost-efficiency in your application. Ultrasonic flow meters operate by sending high-frequency sound waves through a fluid to measure its velocity. The two primary methods are Doppler and transit-time, with transit-time being the most widely used for clean liquids and gases. Transit-time flow meters calculate flow based on the difference in time it takes for an ultrasonic signal to travel with and against the flow direction. This method offers high accuracy and is commonly used in custody transfer applications for natural gas and petroleum liquids, where pr...
