When selecting a flow meter for oil or diesel applications, accuracy is often the first factor that comes to mind. But there's another critical specification that can make or break performance in real-world conditions — turndown ratio . Also known as rangeability, turndown ratio defines the range over which a flow meter can maintain accurate measurements, from its highest to lowest detectable flow rate . In demanding environments like oil and gas operations, where flow rates fluctuate dramatically, this metric becomes even more important than raw accuracy. For example, in flare monitoring systems, flow can vary from a small pilot flame to a full emergency blowdown event. A meter with poor turndown might miss low-level leaks or fail during peak flows. That's why engineers are increasingly looking beyond basic accuracy and focusing on how well a meter performs across its entire operating range . Take thermal mass flow meters, commonly used in gas flow applications such as n...
Coriolis flow meters are increasingly popular in the food and beverage industry due to their high accuracy and ability to measure mass flow directly. Unlike traditional volumetric flow meters, Coriolis devices are not affected by changes in fluid density or viscosity, making them ideal for handling a wide range of liquids—from syrups and dairy products to beverages with suspended solids. Their reliability in measuring both flow rate and density simultaneously helps ensure consistent product quality and compliance with strict hygiene standards . However, installing Coriolis flow meters in food and beverage processing lines comes with unique challenges. One major issue is ensuring proper orientation and support to avoid stress on the meter body, which can lead to measurement inaccuracies. These meters are sensitive to mechanical stress and vibration, especially in environments where pumps and mixers are constantly running. Mounting them in a way that minimizes pipe strain is crucial fo...
