    Pressure Equipment Directive The KROHNE organisation complies with the requirements of Module H of the Pressure Equipment Directive 97/23/EC (full quality assurance). Please refer to the CE declaration for more detailed information.

  • Page 8: Mechanical Installation

    Mechanical installation Handling the flowmeter Important: Do not lift the compact flowmeter by the signal converter housing or the terminal box. Check the weight of the flowmeter as indicated on the type plate before handling the unit. When handling the flowmeter avoid hard blows, jolts or impacts.

  • Page 9: Special Installation Requirements

    If required the position of the signal converter can be modified by turning the display circuit board through 90° or 180° to achieve a horizontal position of the display. In addition the signal converter housing may be turned through 90° opposite the flow sensor. For an exact description of this procedure, refer to chapter 8.6.

  • Page 10: Pipe Flanges

    Since gas will collect at the highest point of a pipe, installation of the flow meter at that location should be avoided at all times. Also installation in a down going pipe should be avoided since a completely filled pipe may not be guaranteed due to cascading affects. Additionally flow profile distortion is possible.

  • Page 47: Ultrasonic Measurement Principle

    Ultrasonic measurement principle 12.1 Transit time differential method UFM 3030 operates just like all KROHNE ultrasonic flow meters by the transit-time differential method. This measuring principle is based on a simple physical fact. Imagine two canoes crossing a river diagonally, one with the flow and one against the flow. Naturally the canoe that is travelling with the flow will reach the opposite side sooner that the canoe that is travelling upstream.
