1, the fault phenomenon: instantaneous flow meter fluctuation.
⑴ Cause of failure: signal strength fluctuation; The fluid itself measures large fluctuations.
(2) Treatment countermeasures: adjust the position of the probe, improve the signal strength (keep above 3%) to ensure that the signal strength is stable, if the fluid fluctuation is large, the position is not good, re-select the point, and ensure the working condition requirements of 5d after *d.
2, the fault phenomenon: the external clamp flowmeter signal is low.
(1) The cause of the failure: the pipe diameter is too large or the pipe scale is serious or the installation method is negligent.
(2) Treatment measures: Insert probe is used for large pipe diameter and serious scaling; Select a new installation mode.
3, fault phenomenon: the signal of the plug-in probe is reduced after a period of time.
⑴ Cause of failure: The probe may be offset or the probe surface scale is thick.
(2) Treatment measures: readjust the probe position and clear the probe emission surface.
4. Fault symptom: No display on startup.
(1) Cause of failure: power attribute and meter rating fault or fuse blown.
(2) Treatment countermeasures: Check whether the power attribute corresponds to the rating of the instrument and whether the fuse is blown. If the above problems do not inform the manufacturer’s professional personnel to deal with.
5, fault phenomenon: after the machine is turned on, the instrument only has a backlight without any character display.
⑴ Cause of failure: Generally, the program chip is lost.
(2) Treatment countermeasures: notify the manufacturer’s professional personnel to deal with.
6, the fault phenomenon: ultrasonic flowmeter can not be applied in the field of strong interference.
(1) The cause of the failure: the fluctuation range of the power supply is large or there is a frequency converter or strong magnetic field interference around the ground line is incorrect.
(2) Treatment countermeasures: to provide stable power supply to the instrument; Or install the instrument away from the frequency converter and strong magnetic field interference; Or standard setting ground cable.
1, instantaneous flow meter fluctuation?
A. The signal strength fluctuates greatly; b, the measurement fluid fluctuation;
Solution: Adjust the position of the probe, improve the signal strength (keep above 3%) to ensure that the signal strength is stable, such as the fluid fluctuation is large, the position is not good, re-select the point to ensure that the working condition requirements of 5d after *d.
2. Low signal of external clamp flowmeter?
The pipe diameter is too large, the pipe scale is serious, or the installation method is negligent.
Solution: For the pipe diameter is too large, serious scaling, it is recommended to use the insert probe, or choose the “z” type installation.
3. The signal of the plug-in probe decreases after a period of time.
The probe may be deflected or the probe surface may be thick with scale.
Solution: readjust the probe position and clear the probe emission surface.
4, boot no display
Check whether the power supply properties correspond to the rating of the instrument, whether the fuse is blown, if the above problems are not recommended, it is recommended to send the instrument back to our professional and technical personnel to check.
5, after starting the instrument only backlight, without any character display
This situation is generally lost program chip, it is recommended to send the instrument back to our company for processing.
6, the instrument can not be applied in the field of strong interference?
The fluctuation range of the power supply is large, there are frequency converters or strong magnetic field interference around, and the ground line is incorrect.
Solution: To provide a stable power supply to the instrument, the instrument is installed away from the frequency converter and strong magnetic field interference, there is a good grounding line.
