Basic Requirements on installation of Coriolis mass flow meter
1. Install the meter so that the flow direction arrow on the sensor case matches the actual forward flow of the process.
2. Properly supporting is required for preventing tubes vibrating.
3. If a strong pipeline vibration is inevitable, it is recommended to use a flexible tube to isolate the sensor from the pipe.
4. Flanges should be kept parallel and their center points should be located on the same axis to avoid subsidiary force generation.
5. 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.
Installation Direction
In order to ensure the reliability of the measurement, the ways of installation should consider the following factors
1. The meter should be installed downward when measuring liquid flow (Figure3-1), so that air cannot get trapped inside the tubes.
2. The meter should be installed upward when measuring gas flow (Figure3-2), so that liquid cannot get trapped inside the tubes.
Figure 3-2
3. The meter should be installed sideward when the medium is turbid liquid (Figure3-3) to avoid particulate matter accumulated in the measuring tube. The flow direction of medium goes from the bottom up through the sensor.

Sensor Fiexed for small size Coriolis mass flow meter
Coriolis mass flowmeter is a vibrating instrument, when they work, the two vibrating tube is always in a state of vibration.
Therefore, external vibration or pipeline vibration may have effect on their normal operation.
For small diameter coriolis mass flow meter, it is not easy to avoid vibration because of the small measuring tube, in this
case, we provide installation bracket which is used for fixed. Please make sure that the installation bracket is installed on a
stable interface. The installation diagram for small diameter is shown as Figure 3.4
