Page 5: Safety Instructions
1. SAFETY INSTRUCTIONS 1.1. The flow meter should be mounted (dismounted) by technicians: - Certified for performing work of this type - Having the right to work with electrical installations up to 1000 V - Familiar with all the instructions outlined for the flow meter and auxiliary equipment used for mounting and dismounting. -
Page 6: Mounting
3. MOUNTING 3.1. General Requirements When mounting the MF on site, a free pipeline section should be provided. It is used to mount the flow meter and straight pipe runs of appropriate length upstream and downstream the flow pipe. Overall dimensions and weight of the MF are given in Appendix A of the Operation Manual. - Page 7 - Straight pipe runs with nominal diameter (DN) equal to nominal diameter of the MF should be provided upstream and downstream the MF. Length of the runs should not be less than specified in Table 1. The runs must not include devices or components that may disturb flow structure - When the MF is operated, the flow pipe inner channel should be fully filled with liquid...
- Page 8 Delivery package is agreed with the customer. Set of design documentation for the fitting assembly is available at customer's option. 3.2.3.2. Welding of assembly-welded structure components and connection of the components to the pipeline at flow meter location must be performed in compliance with applicable regulatory documents.
- Page 9 The other (free) end of the adaptor is threaded with straight pipe outer thread - Flow pipe dimension simulator of appropriate size and design (wafer type) - Gaskets - Fasteners. 3.2.4.2. The simulator overall mounting dimensions and DN correspond to the dimensions of the flow meter flow pipe to be mounted with this fitting assembly.
- Page 10 3.2.6. Mounting fitting assembly into the plastic (metal-plastic) pipeline. 3.2.6.1. Before mounting drain liquid from the pipeline and cut the pipeline where the flow meter will be installed. Fix the assembly to stationary supports by clamps where pipeline is cut considering the following condition: threaded holes M5 on cylindrical surface of the flanges used to connect wires to the MF case should be in position allowing easy connection of the wires.
- Page 11 CAUTION! Please make sure that gaskets are aligned relative to the flow pipe inner channel, i.e. a gasket must not even partly cover the inner channel. To provide gasket alignment, it is recommended to fix the gaskets by adhesive. The flow meter shall be mounted into the pipeline when all construction, welding and other works are finished.

Page 12: Wiring The Flow Meter
3.3. Wiring the Flow Meter 3.3.1. Power and communication cables are connected to the MF after it is installed into the pipeline. Cables are passed via corresponding MB through connections and connected to boards of processor and communication modules. Schematics of the input and outputs are given in Appendix B of the Operation Manual. - Page 13 To prevent measuring block from moisture ingress via through connections when using flat section cables it is necessary to connect cables so that falling U-loop is formed in the vertical plane (see Fig.5). a) horizontal b) sloping c) vertical Fig.5. Position of cables at the inlet of through connections when mounting MF into the pipeline 3.3.3.

Page 14: Dismounting
4. DISMOUNTING 4.1. The order of dismounting the flow meter before dispatching for regular calibration or repair is as follows: - Turn off power, then disconnect network and signal cables from the flow meter - Disconnect wires from the pipeline flanges - Cut off liquid at the FS location, make sure that pressure is released and drain the liquid - Dismount the flow meter and install the simulator... -
Page 15: Putting Into Operation
5. PUTTING INTO OPERATION 5.1. When putting the flow meter into operation check the following: - The flow is in the direction of the arrow on the flow meter case - Lengths of the inlet and outlet straight pipe runs of the MF are relevant to the flow reversibility - The flow meter and related equipment are connected in accordance with the selected wiring diagram... -

- Page 24 rings does not provide electrical contact of the MFР case with the fluid being measured. In this case manufacturer doesn't guarantee stable operation of the flow meter. NOTE. When flow meters of Pro-×22М× versions with protection rings are mounted into the plastic (metal-plastic) pipeline, a grounding element ensures electrical contact with the fluid being measured.
