Coriolis Mass Flowmeter is suitable for measuring various non-Newtonian fluids, slurries, suspensions, high viscosity fluids and other media.
The T-series Triangle Coriolis Mass Flowmeter can directly measure the mass flow rate of the fluid in the closed pipe and the density of the medium. The T series Coriolis mass flowmeter has a triangular sensor structure. The smallest diameter can be DN3. This structure flowmeter is easy to measure when the instantaneous flow is small. The compact triangular shell structure saves installation space. The installation is simple and superior Downstream straight pipe requirements
Sino-Inst offers a variety of Mass flow meters for High Viscosity Liquids flow measurement. If you have any questions, please contact our sales engineers.
Features of T-series Triangle Coriolis Mass Flowmeter

Coriolis Mass Flowmeter Working Principle
The principle of Coriolis mass flowmeter mass measurement is Newton’s second law F=Ma. When the fluid flows in the vibrating tube, it will produce Coriolis force proportional to the mass flow.
When there is no fluid flowing, the vibrating tube will not be twisted, and the signals detected by the electromagnetic signal detectors on both sides of the vibrating tube are in phase.
When fluid passes by, the vibrating tube will be twisted under the action of torque, and there will be a phase difference between the two detectors.
The transmitter measures the lag time between the left and right detection signals. This time difference is multiplied by the flow calibration coefficient to determine the mass flow.
The density measurement principle of Coriolis mass flowmeter is that the vibration frequency is inversely proportional to the square root of the fluid density. The fluid density is determined by measuring the vibration frequency.
Therefore, the mass flow meter can realize the measurement of fluid mass flow and the measurement of fluid density.
How does a T-series Triangle Coriolis Mass Flowmeter 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 flowmeter 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
