Massestrømmemålere

Massestrømmemålere, often referred to as mass flow meters, are instruments used to measure the mass of a fluid passing through a pipe per unit of time. This is distinct from volumetric flow meters, which measure the volume of fluid. Mass flow meters are particularly useful when dealing with fluids whose density can change significantly due to temperature or pressure variations, as the mass flow rate will remain constant under such conditions.

There are several types of mass flow meters, including Coriolis flow meters and thermal mass flow meters. Coriolis flow meters operate based on the Coriolis effect, where a vibrating tube through which the fluid flows experiences a twist proportional to the mass flow rate. Thermal mass flow meters measure the amount of heat transferred from a heated element to the fluid, which is directly related to the mass flow rate.

The primary advantage of mass flow meters is their independence from fluid density variations. This leads to higher accuracy and reliability in many industrial processes. They are widely used in industries such as oil and gas, chemical processing, pharmaceuticals, and food and beverage for applications like metering fuel, controlling chemical reactions, and dispensing ingredients. The precise measurement of mass flow is critical for process control, safety, and economic efficiency.
