To meet the above specifications, the transmitter must be installed with an approved Micro Motion sensor, and the sensor cable must be either doubly shielded with full contact glands, or installed in continuous, fully bonded metallic conduit. The transmitter and sensor must be directly connected to a low-impedance (less than 1 ohm) earth ground.

• Page 103: Appendix C Theory Of Operation

  Appendix Theory of Operation The flow tubes of the Coriolis mass flow sensor are driven to vibrate at their natural frequency by a magnet and drive coil attached to the apex of the bent tubes (see Figure C-1). An AC drive control amplifier circuit in the transmitter reinforces the signal from the sensor’s left velocity pickoff coil to generate the drive coil voltage.

• Page 104
  Theory of Operation continued Mass flow measurement The vibrating motion of the flow tube, combined with the momentum of the fluid flowing through the tubes, induces a Coriolis force that causes each flow tube to twist in proportion to the rate of mass flow through the tube during each vibrational cycle.

  The transmitter software contains a simplification of this correlation to maximize sampling frequency of the measurement. Accuracy of the Micro Motion correlation is ±0.0005 g/cc (±0.5 kg/m relative to the API-2540 equation. After temperature correction to 60°F (15°C), the density is converted to °API by the following expression:…

  Theory of Operation continued Pressure compensation A pressure transmitter can be connected to the RFT9739 for pressure compensation. The RFT9739 or an external source can supply power to the pressure transmitter. If the input is configured to indicate gauge pressure, the transmitter uses the pressure input to account for effects of pressure on the flow tubes of certain sensors.

  Appendix Replacing Older Transmitters Step 1 Disconnecting the old transmitter WARNING Hazardous voltage can cause severe injury or death. Shut off power before disconnecting the transmitter. CAUTION Process control will stop when the transmitter is disconnected. Set control devices for manual operation before disconnecting the transmitter.

  • If the serial number is 87263 or lower, check resistance values as described below. b. If the sensor and transmitter were properly wired with Micro Motion color-coded cable, the orange and violet wires provide temperature detection. These wires were connected to RE-01 terminals 3 and 9, or RFT9712 terminals 3 and 7, or RFT9729 terminals CN1-14d and CN1-16d.
