What to do if Siemens Measuring Instruments display shows no flow?

  If the Siemens Measuring Instruments display shows no flow, it could be due to several reasons: the pipe is not filled with liquid (ensure the pipe is filled, or at least the sound path is covered with liquid); a broken or detached cable (ensure the sensor cable is connected in the terminal housing of the transmitter and that the screen and center pin are connected inside the sensor top); or a permanent disturbance inside the pipe (if possible, ensure that the sensor window inside the pipe is not damaged and that no permanent disturbance is present).

Why is the flow not stable on my Siemens Measuring Instruments?
- W
  Wendy NealAug 7, 2025
  Unstable flow readings on your Siemens Measuring Instruments can be attributed to a few potential issues. It could be that air bubbles or particles are disturbing the measurement; ensure the pipeline is ventilated and the concentration of particles is limited. Another cause might be partly connected cables; double-check that the sensor cables are connected in the transmitter and in the sensors, and verify the connection of the cable grounding shield, ensuring the shield and center pin are connected inside the sensor top. Lastly, ultrasonic echoes could be the problem; verify that the entered path lengths correspond to the measurement report.

How to fix negative flow display on Siemens SITRANS F FST030?
- M
  Miss Angela WallaceAug 12, 2025
  If your Siemens Measuring Instruments device is displaying negative flow, the issue could stem from incorrectly connected sensor cables; ensure they are connected correctly: 1A to 1A, 1B to 1B, 2A to 2A, and 2B to 2B. Alternatively, the measurement direction might be set incorrectly; verify that the setting of menu 3.1.5.1 is '+ Direction'.

What to do if pulse/frequency output does not work on Siemens Measuring Instruments?
- R
  Ryan JohnsonAug 17, 2025
  If the pulse/frequency output on your Siemens Measuring Instruments is not working, it could be due to an internal electrical failure. Start simulation on the pulse/frequency output via menu 2.4, coupling the frequency measuring instrument directly on the terminals. Another potential cause is that the pulse/pause or frequency is out of range; adjust the pulse or frequency output settings in menu 4.2.

Why does Siemens SITRANS F FST030 Measuring Instruments display 0 flow with device status OK?
- C
  Carl KingAug 21, 2025
  If your Siemens Measuring Instruments device displays 0 flow but the device status is "OK", it could be because the process flow value is very low compared to the low flow cut-off limit of the device. For testing purposes, check that the low flow cut off (menu 3.1.6) is set to 0. It could also be due to mismatched sensor cables; for testing, check that the low flow cut off (menu 3.1.6) is set to 0.

What causes a dark or partly dark LCD display on Siemens Measuring Instruments?
- N
  nsimmonsAug 27, 2025
  A dark or partly dark LCD display (missing characters) on your Siemens Measuring Instruments could be caused by an internal electrical failure. Turn off the power and check the connections for the power supply PCBA and the flat cable for the display module. If the display is partly dark, start the display test (menu 2.3.2.).
