Page 3: Introduction
The present manual covers procedures for on-site mounting and dismounting of AFLOWT UF ultrasonic flowmeters of UF-510 d, -520 d, -522 d, -530 d, -540 d, -542 d, -544 d models. In the course of work, al- so refer to manuals "ULTRASONIC FLOW METER AFLOWT UF (with cut-in converters). -
Page 4: Safety Instructions
1. SAFETY INSTRUCTIONS 1.1. The flowmeter should be mounted (dismounted) by the qualified tech- nical 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 - Upon reading all the instructions for the flowmeter and the auxiliary equipment used for mounting and dismounting. -

3. MOUNTING REQUIREMENTS 3.1. Requirements for Mounting the Primary converter 3.1.1. General Requirements. 3.1.1.1. The following requirements should be observed on-site of CP mounting: - Liquid pressure in the pipeline and operation conditions must not be of values that may facilitate gas (air) release and/or accumulation - When the flowmeter is operated, the pipeline should be fully filled with liquid - Flow turbulence and pulsations are minimal. -
Page 6: Placing The Pea Pair For Two-Beam Sounding
3.1.3. Placing the PEA pair for two-beam sounding In case of two-beam scanning, the wetted PEAs should be mount- ed on the CP along two chords. The CP should be mounted so that the chords are directed horizontally (Fig.3). PEA1.1-PEA1.2 pair – 1st beam PEA2.1-PEA2.2 pair –... -
Page 7: Length Requirements For Straight Pipe Runs
3.2. Length requirements for straight pipe runs 3.2.1. For proper flowmeter’s operation, before the first and the last PEA with respect to the flow direction, there should be straight pipe runs of corre- sponding length with the DN equal to the DN of the CP. The “type” in- stallation minimum values of relative length of the straight pipe runs for various PEA installation configurations and types of hydraulic resistance are shown in Table A.1 of Appendix A... -

4. MOUNTING THE FLOWMETER 4.1. Mounting the Primary Converter 4.1.1. In order to install the CP into the pipeline the following fittings are to be delivered: companion flanges, pipe adaptors, taper adaptors (if the DN of the primary converter is less than the DN of the pipeline intended for mounting the CP). -
Page 9: Wiring The Flowmeter
4.3. Wiring the Flowmeter 4.3.1. When connecting PEAs to the CS, it is necessary to provide that the el- ements of the measuring channel (PEAs and communications cables) be in correspondence with the characteristics of the channel. PEA serial numbers with the measurement channel indicated are specified in the flowmeter’s Passport. - Page 10 4.3.8. The need for protective grounding is determined by power supply and environment conditions under which the flow meter is operated. The protective grounding and earthing device should correspond to the rules on design of power electric installations. Do not use the light- ning protection system for grounding since in could result in device's failure.

Page 11: Start-Up Procedure
5. START-UP PROCEDURE 5.1. Before start-up you should check that flowmeter’s operation parameters specified in the Passport correspond to data entered in the flowmeter memory. 5.2. Parameters of PEA are entered according to the Operation Manual, Sections 2.1 Part II. 5.3. -
Page 12: Dismounting
6. DISMOUNTING 6.1. To dismount the flowmeter, do the following: - Switch off the flowmeter - Before dismounting the CP, cut off liquid flow in the pipeline section where they are located, ensure there is no pressure in the pipeline and drain the liquid - Disconnect cables leading to the CS (PEAs) - Dismount the CP and CS. -
