Why is the output signal deviating from the measured quantity in my YOKOGAWA Rotamass Prime Measuring Instruments?
- R
  Rachel BrownAug 20, 2025
  If the output signal is deviating from the measured quantity in your YOKOGAWA Measuring Instruments, it could be due to: * An incorrect parameter setting. Check the parameter LRV and URV of the corresponding output signal, and correct if necessary. * An incorrect measured quantity being output. Check the measured quantity output and, if necessary, correct; check parameter Sel.

Why is the zero point unstable on my YOKOGAWA Rotamass Prime Measuring Instruments?
- D
  Denise WeberAug 23, 2025
  Several factors can cause an unstable zero point. These include: * Mechanical strain from traction or pressure: Eliminate the source of mechanical tension. * Terminal board or connection terminals of the transmitter or sensor being soiled or damp: Clean the terminal board and connection terminals. Clean and dry the transmitter and/or sensor, and seal them tightly. * Influence of external vibration: Install mechanical dampers or increase the mass flow damping parameter (see the applicable software instruction manual).

Why is the flow rate displayed deviating from the actual flow rate in my YOKOGAWA Rotamass Prime Measuring Instruments?
- F
  frank06Aug 26, 2025
  If the flow rate displayed on your YOKOGAWA Measuring Instruments is not matching the actual flow rate, there might be several reasons: * The zero point may be set incorrectly, requiring you to set the zero point correctly. * The highest and lowest values for mass flow could be set incorrectly. Ensure you match the settings of the flow meter and reading system, and check the LRV and URV process parameters. * The measuring tubes may not be completely filled with the medium. Ensure correct installation. * There might be bubbles in the medium, which requires checking the pipe and installation. * For remote types, the connecting cable might be incorrectly connected. Check the cable connections and correct them if necessary.

What to do if the field communicator is not detected by YOKOGAWA Measuring Instruments?
- N
  Nicholas VargasSep 4, 2025
  If your field communicator is not being detected by YOKOGAWA Measuring Instruments, it could be due to the following reasons: * The HART or Modbus DD may not be installed on the field communicator. Save the HART or Modbus DD file on the field communicator. * The field communicator may not be properly connected. Connect the field communicator with Rotamass Total Insight.

How to make settings if IR switches are not working on YOKOGAWA Rotamass Prime Measuring Instruments?
- J
  Joshua ShermanSep 7, 2025
  If you cannot make settings via the IR switches on your YOKOGAWA Measuring Instruments, it may be due to incorrect settings in the write-protect menu item. Switch off the write-protect menu item via digital communication or hardware switch.

Why is the zero point unstable on YOKOGAWA Rotamass Prime?
- C
  Cynthia ThomasSep 9, 2025
  An unstable zero point can be caused by several factors: * The measuring tube not completely filled with fluid: Ensure the measuring tube in the sensor is completely filled with fluid. Check the installation. * Bubbles or solids in the fluid: Inspect the pipe and sensor installation. * No electrical grounding: Ground the transmitter and sensor, and check the correct connection of the connecting cable shield on the transmitter.

Why is the zero point unstable on YOKOGAWA Rotamass Prime Measuring Instruments near electromagnetic fields?
- N
  nbowenSep 14, 2025
  If the flow meter is installed near facilities with a strong electromagnetic field, this can cause an unstable zero point. Ground the transmitter and sensor, and install the flow meter as far away as possible from these electric devices.

What to do if the zero point is unstable on YOKOGAWA Measuring Instruments?
- C
  Catherine BatesNov 17, 2025
  If the zero point on your YOKOGAWA Measuring Instruments is unstable, consider these potential causes: * The measuring tube may not be completely filled with the medium. Check that the measuring tube in the sensor is completely filled. * There may be bubbles or solids in the medium. Check the pipe and sensor installation and correct the installation if necessary. * There might be no electrical grounding. Ground the transmitter and sensor, and check the correct connection of the connecting cable shield on the transmitter. * The flow meter may be installed in proximity to facilities with a strong electromagnetic field. Ground the transmitter and sensor and install the flow meter as far away as possible from these electric devices. * Mechanical strain from traction or pressure may ...
