Coriolis mass flow meters are the most accurate measuring method in the world. The coriolis flow meter working principle and measuring principle are used in a wide range of different branches of industry, such as the life sciences, chemicals, petrochemicals, oil and gas, food, and- no less importantly - in custody transfer applications. Coriolis density meter can measure virtually all fluids: cleaning agents, solvents, fuels, crude oil, vegetable oils, animal fats, latex, silicon oils, alcohol, fruit solutions, toothpaste, vinegar, ketchup, mayonnaise, gases or liquefied gases.
The Sincerity DMF series micro bend V-shape is the standard high performance coriolis mass flowmeters for the process industry. The U shape bent tube meter offers superior performance and high accuracy in virtually any application. From process control in (petro) chemical applications to concentration measurements in the food and beverage industry to custody transfer filling and transport measurements in the oil and gas industry. Its high-end options also make the DMF-1 Series U-shape the optimum device for cryogenic media like Liquefied Natural Gas (LNG) with temperatures down to -200°C / -392°F as well as applications involving high operating temperatures (up to 350°C / 662°F) or pressures (up to 1000 barg / 14504 psig).
Coriolis flow measuring principle
Each coriolis type flow meter has one or more measuring tubes which an exciter causes to oscillate artificially. As soon as the fluid starts to flow in the measuring tube, additional twisting is imposed on this oscillation due to the fluid’s inertia. Two sensors detect this change of the tube oscillation in time and space as the “phase difference.” This difference is a direct measure of the mass flow.
In addition, the fluid density can also be determined from the oscillation frequency of the measuring tubes. The temperature of the measuring tube is also registered to compensate thermal influences. The process temperature derived from this is available as an additional output signal.
How does a Sincerity Coriolis flow meter measure mass flow and density?
Coriolis mass flow measurement is the MOST ACCURATE FORM for a flow measurement for a wide range of industrial processes. Each coriolis mass meter has one or more measuring tubes.
As soon as the fluid starts to flow in the measuring tube, additional twisting is imposed on this oscillation due to the fluid's inertia. Two sensors detect this change of the tube oscillation in time and space as the “phase difference.”
Phase difference= mass flow
Oscillation frequency= density
