    LRF-6000H Ultrasonic flowmeter Setup Menu – Calibration 0. Scale factor: Scale factor refers to the ratio between “actual value” and “reading value”. For example, when the measurement is 2.00, and it is indicated at 1.98 on the instrument, the scale factor reading is 2/1.98.
  • Page 14 LRF-6000H Ultrasonic flowmeter Generally, 0.03m/s is recommended to enter as the low flow cutoff point. The low flow cutoff value has no relation to the measurement results once the velocity increases over the low flow cutoff value. 4. Manual zero point: This method is not commonly used.

  • Page 20: Measurement Site Selection

    LRF-6000H Ultrasonic flowmeter Measurement Site Selection When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed to guarantee a highly accurate measurement. Please follow these guidelines for selecting a proper measurement installation site: Choose a section of pipe, which is always full of liquid, such as a vertical pipe with flow in the upward direction or a full horizontal pipe.
  • Page 21: Transducer Installation

    LRF-6000H Ultrasonic flowmeter Transducer Installation Before installing the transducers, clean the pipe surface where the transducers are to be mounted. Remove any rust, scale or loose paint and make a smooth surface. Choose a section of sound conducting pipe for installing the transducers. Apply a wide band of sonic coupling compound down the center of the face of each transducer as well as on the pipe surface, and then attach the transducers to the pipe with the provided racks and tighten them firmly.
  • Page 22: Method

    LRF-6000H Ultrasonic flowmeter V Method The V method is considered as the standard method. It usually gives a more accurate reading and is used on pipe diameters from 25mm to 400mm (1” ~16”). It is convenient to install, but still requires proper installation of the transducers. It is in contact with the pipeline at the centerline of the pipeline, and the spacing on both sides of the centerline is equal.
  • Page 23: N Method (Not Commonly Used)

    LRF-6000H Ultrasonic flowmeter N Method (not commonly used) With the N method, the sound waves traverse the fluid twice and bounce three times off the pipe walls. It is suitable for small pipe diameter measurement. The measurement accuracy can be improved by extending the transit distance with the N method (commonly used).
  • Page 24: Transducer Mounting Inspection

    LRF-6000H Ultrasonic flowmeter Transducer Mounting Inspection Check if the transducers are installed properly and accurate and strong enough ultrasonic signal to make sure proper operation and high reliability of the transducers. Confirm them by checking the detected signal strength, total transit time, delta time and transit time ratio. The installation condition directly influences the flow value accuracy and system long-time running reliability.
  • Page 25: Transit Time Ratio

    LRF-6000H Ultrasonic flowmeter Transit Time Ratio Transit Time Ratio indicates if the transducer mounting spacing is accurate. The normal transit ± time ratio should be 100 3 if the installation is proper. Check it in “Main Menu”. ± If the transit time ratio is over 100 3, it is necessary to check: (1) If the parameters (pipe outside diameter, wall thickness, pipe material, liner, etc.) have been set correctly,...
  • Page 26: Operating Instructions

    LRF-6000H Ultrasonic flowmeter Operating Instructions Zero Cut When static flow with zero flow rate, set a zero point in the flow meter. It is indicated as zero when the measurement flow rate reach to zero. When necessary to establish the true zero flow condition, set it in the flow meter.
