    4. When welding is performed, DO NOT use the flowmeter with PFC installed. Install the PFC dimension simulator provided in the delivery package. 5. MFT mounted in the pipeline SHOULD NOT be rotated around the pipeline axis. 6. When mounting and using MFT, DO NOT remove protection rings from PFC.

    1. SAFETY INSTRUCTIONS 1.1. The flowmeter should be mounted (dismounted) by the qualified technical staff: - Certified for performing work of this type on the site where the flowmeter is installed and authorized by the manufacturer - Authorized to work with electrical installations up to 1000 V - Familiar with the instructions for the flowmeter and the auxiliary equipment used for mounting and dismounting.

    - The flowmeter should be mounted in the part of a pipeline where liquid turbulence and pulsations are minimal. Fig.1. Recommended MFT locations - Straight pipe runs with nominal diameter (DN) equal to nominal diameter of the flowmeter and length of no less than specified in table 1 should be provided upstream and downstream the flowmeter.

After completing the work, remove burrs and scales from the inside. c) Assemble the whole structure using bolts (studs) to fix components. Please make sure that the simulator is installed instead of PFC to provide alignment between two welded units, flatness/parallel alignment of the flanges, and to avoid damages to the flowmeter in the course of welding the structure to the pipeline.
  • Page 8 When mounting the flowmeter, put new gaskets provided in the delivery package into the companion flanges.  When mounting flanged type flowmeters into the pipeline, bolt PFC/pipeline mating flanges from the side of the pipeline flanges. Length of the bolts must provide the minimal distance of 3 mm from a bolt end to the flowmeter’s assembly.

    The flowmeter mounted in the pipeline SHOULD NOT be rotated around the pipeline axis. 3.2.7. Mounting the flowmeter with threaded coupling 3.2.7.1. Select the flowmeter’s pipeline mounting location observing the rules specified in Table 1. Cut the pipeline drained of liquid following the instructions given in section 3.2.6.

    protrusion as shown in Fig.C.4, after which the top plate is secured with screws. 3.4. Wiring the Flowmeter 3.4.1. Power and communication cables are connected to the flowmeter after it is installed into the pipeline. Prior to connection, cut isolation from cable ends by 5 mm and after that, connect them to the terminals on the switching module.

    DO NOT fix cables to the heated pipeline. 3.4.7. To provide electrical connection, it is necessary to connect the pipeline sections cut in the wafer type MFT mounting location by wires (jumpers) via a terminal located on the BE; wires should be of 4 mm cross section as a minimum (see Appendix A).

    Immediately after PFC is dismounted from the pipeline, install the clamping plates with the tightening stud (bolt) on PFC covered by fluoroplastic with the protection rings removed - Install the simulator in the pipeline instead of PFC. 4.2. On installing the simulator, check mating surfaces for leakage. Replace gaskets, if necessary.
