    The present manual covers the procedures for on-site mounting and dismounting of "AFLOWT LV" ultrasonic Level gauges of LV-2xx versions. In the course of work, also refer to "ULTRASONIC LEVEL GAUGE AFLOWT LV. LV-2xx version. Operation manual, Part I and Part II"...

  • Page 4: Safety Instructions

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

  • Page 5: Preparation For Mounting

    2. PREPARATION FOR MOUNTING 2.1. To mount the Level gauge on site, the following areas should be available: - Free channel (tank, pipeline) section for mounting an acoustic system (AS) - Free space used to place structures providing protection of AS from precipitation, wind, and solar/heat radiation - Free area suitable for positioning BMD, SPS and CB (Communication Block).

  • Page 6: Mounting Considerations

    3. MOUNTING CONSIDERATIONS 3.1. Site requirements for mounting AS should be as follows: - Tank (channel, pipeline) operation conditions exclude foreign items on the surface of media interface within the area of measurements - Liquid turbulence and pulsations are absent or minimal - Foams on the surface of media interface are minimal - There are no structural components on the way of acoustic beam from PEP to the media interface...

    4. MOUNTING THE LEVEL GAUGE 4.1. Types of acoustic systems 4.1.1. Simplistically designed AS-1xx-xx3 systems come without reference reflectors and sound guides. AS-11x-xx3 systems is equipped with disc mount ones (Fig.A.1). Mount disc both have holes for fixing an acoustic system to the object under control.

    4.2.4. AS-40x-xx0 and AS-6xx-xx0 systems are mounted as shown in figures B.2-B.4. Several mounting methods are available: - Mounting AS on a frame installed on the object under control (Fig.B.2). AS mount flange is fixed to the frame by bolts. Deflection of the base plane of the mount flange from the horizontal plane is checked with a builder's level in two mutually perpendicular directions.

To avoid mechanical damages, it is recommended to place all cables in metal or plastic tubes, corrugated sleeves, and cable trays, trunks, or conduits.

    5. START-UP PROCEDURES 5.1. Initial configuration 5.1.1. Prior to work, it is necessary to check that the Level gauge's operation settings specified in the Equipment Certificate or Check Form correspond to the ones in the Device's internal memory as well as to check its configuration settings.

  • Page 11: Configuring The Level Gauge Installed On The Object Under Control

    5.2.1. Configuration procedure is performed after determining all initial settings and completing all mount procedures. The Level gauge is configured from the keyboard, which is operated as described in "ULTRASONIC LEVEL GAUGE AFLOWT LV. LV-2xx version. The operation manual,...
  • Page 12 Part II" document. Also, the Level gauge can be configured from a PC with use of "Monitor AFLOWT LV-2xx" software. 5.2.2. The Level gauge is switched to SERVICE mode, and then powered on. Setting/ Configuration menu is opened and the following parameters are set for each channel: - Calc.

    is necessary to check that the signals reflected from the media interface and reference reflector (for AS with reference reflector) are displayed. If the Device is configured correctly, the measured distance is equal to the actual distance, and positions of the selection marker and the desired echo-signal match on the display.
  • Page 14 5.3.3. Prior to configuration, measurement base B (section 5.1.2) is determined along with an actual value of liquid level in the tank Н The measurements are performed with other measuring tools (e.g., measuring needle, measuring rod etc). At the same time, the actual level value is measured by the Level gauge, and the following readings are taken from the Device's display: distance D′, ultrasound velocity C′, and gas medium temperature t′.

    6. DISMOUNTING To dismount the Level gauge before dispatching for regular calibration or repair, it is necessary to: - Turn power off the Device - Unscrew 6 screws fixing the Measurement Subblock to the Mount Module from the front panel side - Disconnect signal cables connecting BMD with external devices from the terminal blocks - Screw 6 screws fixing the Measurement Subblock to the Mount Module...
