1.3 Working Principle

If a pipe is rotated around a point (P) while liquid is flowing through it (toward or away from the center of rotation), that fluid will generate an inertial force, with reference to 
A particle (δ_m) travels to the right at a constant velocity (v) inside a tube. The tube is rotating around a fixed point (P) at angular velocity (w), in this case, this particle will get two acceleration components:
Normal acceleration (centripetal acceleration), its value is equal to w²r, its direction is toward the point P
Tangential acceleration a₁ (Coriolis acceleration), its value is equal to 2wv, its direction is perpendicular to v

For special rotational pipe, its frequency is constant, ΔFc only depends on δqm. Therefore, directly or indirectly measuring the Coriolis force can be measured mass flow. This is how Coriolis mass flow meter works.

The actual flow sensor can't achieve rotational movement, replace by pipeline vibration. The principle is shown in Figure1.2,Figure1.3,Figure1.4. Both ends of a bend pipe are fixed, and the vibration force is applied to the pipe in an middle of the two fixed points (according to the resonance frequency of pipeline), taking the fixed point as axis, making pipeline vibrate at its natural frequency (w). When no fluid flows through the pipeline, the pipeline is only affected by vibration force, the vibration direction of two half-section of pipeline is the same, no phase difference. When fluid flows, by the influence of fluid medium dot Coriolis force Fc inside the pipeline (In the two half-section of pipeline, Coriolis F1 and F2 are equal in magnitude and opposite in direction Figure 1.2), two half-section of pipeline occur twist in the opposite direction to generate phase difference which is proportional to mass flow. The design of sensor is converting the measurement of Coriolis force to the measurement of phase difference for both sides of the vibrating tube. This is the working principle of Coriolis mass flow meter.

3 Selection and Installation

3.1 Selection

The following conditions should be considered for flow meter selection.

Medium characteristics	Measurability Coriolis mass flow meter is widely used for lots of fluid, but some conditions like slug flow, pulsating flow etc, where you want to install Coriolis mass flow meter, some appropriate support measures must be taken. Corrosivity Coriolis mass flow meter measuring tube material is SS316L, housing material SS304. If the standard material is not suitable for the medium, anticorrosion wetted material should be selected. Operating temperature and pressure Standard configuration: -50…+200ºC, 4.0MPa, please contact with manufacturer for special parameters. Ambient condition Standard ambient temperature is -20…+60ºC. The flow meter will fail to display if the ambient temperature exceeds the standard range. Please contact with manufacturer for special parameters. Protection and Explosion Transmitter ex-proof: flame type, Sensor ex-proof: intrinsic type Transmitter and Sensor protection: IP67
Preferred measuring range	1/3~2/3 of standard flow range
Allowable pressure loss	Pressure loss should be considered especially for reduced pipe. Pressure loss reference table is shown as below

3.2.1 Basic Requirements on installation

• Flow direction should be in accordance with MTCMF sensor flow arrow.
• Properly supporting is required for preventing tubes vibrating.
• If a strong pipeline vibration is inevitable, it is recommended to use a flexible tube to isolate the sensor from the pipe.
• Flanges should be kept parallel and their center points should be located on the same axis to avoid subsidiary force generation.
• Installation vertically, make the flow from the bottom up when measuring, meanwhile, the meter should not be installed on the top to prevent air getting trapped inside the tubes.
