    1 BCMF Mass Flow Meter Overview Befa coriolis mass flow meter (BCMF) is a new type flow meter which is designed according to Micro Motion and Coriolis principle. This kind of new flow meter can measure the fluid directly in a sealed pipeline. It consists of two sections: Sensor and Signal Transmitter.

  • Page 6: Working Principle

    1.3 Working Principle If a pipe is rotated around a point (P) while liquid is flowing through it (toward or away from the center of rotation), that fluid will generate an inertial force, with reference to Figure 1-1: Figure 1-1 A particle (δ...

    3 Selection and Installation 3.1 Selection The following conditions should be considered for flow meter selection. Medium characteristics  Measurability Coriolis mass flow meter is widely used for lots of fluid, but some conditions like slug flow, pulsating flow etc, where you want to install Coriolis mass flow meter, some appropriate support measures must be taken.

  • Page 13: Installation

    3.2 Installation 3.2.1 Basic Requirements on installation  Flow direction should be in accordance with BCMF sensor flow arrow.  Properly supporting is required for preventing tubes vibrating.  If a strong pipeline vibration is inevitable, it is recommended to use a flexible tube to isolate the sensor from the pipe. ...
  • Page 14 Figure 3-2 The meter should be installed sideward when the medium is turbid liquid (Figure3-3) to avoid particulate matter accumulated in the measuring tube. The flow direction of medium goes from the bottom up through the sensor. 3. 2.3 Sensor Fixed Coriolis mass flowmeter is a vibrating instrument, when they work, the two vibrating tube is always in a state of vibration.
