Prior to installation, it is necessary:

• Thoroughly clean the pipeline of dirt, sand, and other solid particulates;
• Inspect the flanges and the measuring tubes of the coriolis mass flow meter and remove solid debris and other particulates from them;
• Remove the preservative grease from the coriolis mass flow meter, by flushing with kerosene, gasoline or diesel fuel.

To install the coriolis mass flow controller in the pipeline do the following steps (see Figure 2.5):

• Arrange the coriolis mass flow controller so that the arrow on the sensor’s body corresponds to the process flow direction;
• Slide the bolts through the holes of one of the pipeline flanges and coriolis controller’s flange, put washers and nuts. Nuts should not be finally tightened at this point;
• Put the gasket between the pipeline flange and coriolis controller’s flange and align it. It is recommended to avoid protrusion of the gasket into the pipeline opening;
• Install the gasket between the other pair of flanges; slide the bolts through the holes of the flanges, put washers and nuts. Nuts should not be finally tightened at this point;
• Tighten the nuts in the sequence shown in Figure 2.6.

When installing the coriolis flow controller any bending or torsional load on the joints should be avoided. Mating flange misalignment should be avoided.

Transmitter of the separate type of the coriolis flow controller can be mounted as shown in Figure 2.7. Transmitter can be mounted with brackets or clamps to the rack, pipe or wall.
