To prepare for the installation of the coriolis mass flow meter, it is necessary:
Linst = Lm + 2*Lg + 2*Lf, (2.1)
where Lm – coriolis mass flow controller length (see Appendix );
Lg – gasket thickness;
Lf – connection kit flange thickness minus thickness of flanges on the pipeline;
|In the process of installation the coriolis gas flow meter may be used instead of the replacement mounting part only in the following cases:
– installation is carried out using gas welding;
– when installing using arc welding,the power source must connected in a way that prevents the welding current to run through the coriolis gas flow meter – see Figure 2.3.
Figure 2.3 Connecting the power source for arc welding using the coriolis mass flow meter
As a result, the installation location must be as shown in Figure 2.4, where the length L is the sum of the length of the coriolis mass flow meter and thickness of the two gaskets.
|When using filters or gas separators, the length L should be sufficient for their installation.|
