Coriolis Flowmeters MC Series


The FLOWMEET Coriolis mass flowmeters of the MC series have the most accurate measurement method for both liquid and gas measurement. Coriolis flow meters can measure almost any fluid: cleaning products, solvents, fuels, crude oil, gases or liquefied gases. They consist of a sensor and a computer. The mass flow meter is equipped with digital transmission equipment based on a digital signal processor (DSP), said processor integrates the processing of a vibration signal through a digital control of the closed loop type. Online node configuration, fault diagnosis and data logging can be done by the computer through HART or PC through Modbus RS-485 communication. The computer will not only calculate the flow rate of the process, the accumulated volume and the composition; they also provide mass flow, density and temperature online in real time.

Technical data  

The MC Series offers superior, high-precision performance in virtually any application. It is suitable for process control in petrochemical applications to concentration measurements in the food and beverage industry and custody transfer measurements in the oil and gas industry. The MC series represents the optimal device for cryogenic media such as liquefied natural gas (LNG) with temperatures down to -200 ° C, as well as applications involving high operating temperatures (up to 350 ° C) or pressures (up to 1000 barg / 14504 psig).

The process temperature derived from this is available as an additional output signal.

  • For all industries and all process and custody transfer applications.

  • Universal measuring principle for liquids and gases.

  • Multivariable measurement: simultaneous measurement of mass flow, density, temperature

  • High measurement accuracy: typically ± 0.2%, ± 0.1%, optional: ± 0.05%

  • Independent measurement principle of physical fluid properties and flow profile.

  • Easy to install (low risk of gas bubble inclusion)

  • No recalibration required when changing fluid

  • No need for straight line installation

  • No need for temperature or pressure compensation.

  • No periodic recalibration required

Description of the coriolis flowmeter

Each Coriolis flow meter has one or more measuring tubes that are physically oscillated by an exciter. As soon as the fluid begins to flow in the metering tube, additional torque is imposed on this oscillation due to the inertia of the fluid. Two sensors, located at both ends of the tubes, detect this change in the oscillation of the tube in time and space as the "phase difference". This difference is a direct measure of the mass flow. Furthermore, the density of the fluid can also be determined from the oscillation frequency of the measuring tubes. The temperature of the measuring tube is also recorded to compensate for thermal influences.

Phase difference is proportional to mass flow.

Oscillation frequency is proportional to density.
