Professional Mass flow meter Manufacturer, Supplier

A mass flow meter is a type of flow meter and is a device that accurately measures the mass flow rate of a fluid moving through a pipe. Mass flow rate differs from volumetric flow rate – which measures volume per unit time. Mass flow rate measures mass per unit time. Mass flow measurement is the basis of most recipe formulations, material balance determinations, billing, and custody transfer operations throughout industry. With these being the most critical flow measurements in a processing plant, the reliability and accuracy of mass flow detection is very important. Coriolis mass flow meter measurement is the basis of most recipe formulations, material balance determinations, billing, and custody transfer operations throughout industry. With these being the most critical flow measurements in a processing plant, the reliability and accuracy of mass flow detection is very important.

The two flow technologies that are used to measure mass flow are inertial and thermal. Inertia meters, known as Coriolis flow meters, use the Coriolis effect to measure mass flow rate. When a fluid is flowing in a pipe and it is subjected to Coriolis acceleration through the mechanical introduction of apparent rotation into the pipe, the amount of deflecting force generated by the Coriolis inertial effect will be a function of the mass flow rate of the fluid. Thermal mass flow meters also measure the mass flow rate of liquids and gases directly and the function on the principles of heat transfer using a heating element and temperature sensors.

Gas mass flow meter working principle

An industrial thermal mass flow meter measures either the mass velocity at a point in aflowinggas, or the total mass flow rate through a channel or pipe. Learn more about thermal mass flow meter technology used to measure gas mass flow meters more efficiently.

Gas Mass Flow Measurement

Positive displacement meters collect a fixed fluid volume, release and refill the fluid, then tally the times the chamber is filled to quantify flow.

Flow measurement devices rely on the flowing stream's strength, as it prevails over a known constriction and indirectly calculates flow.
