In various industries and applications, the accurate measurement of fluid flow is crucial for process optimisation, quality control, and efficiency. Mass flow meters provide a reliable and precise solution for measuring the mass flow rate of gases and liquids. Unlike other flow measurement technologies that rely on pressure differentials or indirect measurements, mass flow meters directly measure the mass of the flowing fluid, making them highly accurate and unaffected by changes in temperature, pressure, or fluid composition.
Before diving into the details of mass flow meters, it is essential to grasp the difference between volumetric flow and mass flow. Volumetric flow refers to the measurement of the volume of fluid passing through a given point per unit of time, typically expressed in litres per minute (L/min) or cubic metres per hour (m³/h). Mass flow, on the other hand, measures the mass of the fluid per unit of time. Liquid mass flow is usually expressed in units such as kilograms per hour (kg/h) or grams per second (g/s). Gas mass flow, however, is mostly indicated in millilitres or litres per minute or hour, with additional “n” for normal temperature and pressure (NTP: 0 °C, 1 atm) or “s” for standard temperature and pressure (STP: 20 °C, 1 atm), for example ln/min or SLM.
Volumetric flow measurements can be affected by changes in temperature and pressure, as well as the composition of the fluid. Mass flow meters, however, provide accurate measurements by directly measuring the mass of the fluid, eliminating the need for additional corrections or compensations based on temperature or pressure variations

1.Thermal mass flow meters: these meters utilise the heat capacity of gases or liquids to measure their mass flow rate. Bronkhorst offers various thermal mass flow meters using different sensor techniques, including:
To summarise, mass flow meters play a crucial role in accurately measuring fluid flow in industrial and scientific applications. With their ability to directly measure mass flow rates and their high accuracy, repeatability, and compatibility with different fluids, mass flow meters offer reliable and precise solutions for optimising processes and ensuring efficient operations. The examples of Bronkhorst products and customer applications highlight the practical use and benefits of mass flow meters in real-world scenarios.
