How to deal with ultrasonic level meter failure?
Ultrasonic level meter in the use of problems do not worry, flow meter manufacturer Aister instrument to help you.
1, ultrasonic level meter water how to do
Solution: If the instrument water, boot without display, it is likely that the instrument circuit board is burned, it is recommended to send the instrument back to the original factory by professional and technical personnel to check.
2, after starting the instrument only backlight, without any character display
Solution: After turning on the instrument only backlight, no other characters show this situation is generally a program chip error, it is recommended to send the instrument back to the original factory for processing.
3, the instrument can not be used in the field of strong interference
Solution: The instrument can not be used in the field of strong interference because the power supply fluctuation range is large, there is a frequency converter or strong magnetic field interference around, and the ground line is incorrect. To provide stable power supply to the instrument, instrument installation away from the frequency converter and strong magnetic field interference, there is a good grounding line. Ultrasonic level meter has strong anti-interference. Can set the upper and lower limit nodes and online output adjustment, and with field display, can choose analog, switching and RS485 output, convenient interface with related facilities.
4, ultrasonic level meter liquid level fluctuation is large how to do
The solution:
1) Increase the range;
2), the average value of multiple measurements;
3) If conditions permit, you can add a pipe to measure the liquid level inside the pipe. Or install an extension tube. The meter is mounted on the pipe. The pipe goes directly to the bottom of the medium and opens a by-pass hole, which can solve the problems of fluctuation and foam.
5. The instantaneous flow value fluctuates greatly
Solution: The fluctuation of instantaneous flow value is manifested as the fluctuation of signal strength and the fluctuation of the measured fluid. The solution is to adjust the probe position, improve the signal strength (keep above 3%) to ensure that the signal strength is stable, such as the fluid fluctuation itself is large, the position is not good, re-select the point to ensure the first 10D after 5D working conditions.
6, ultrasonic level meter probe condensation dew how to deal with
Solution: Various manufacturers of different products, some manufacturers mature technology, probe surface with self-cleaning function, dew can rarely condense! The following methods can also be considered: 1, the surface is coated with lubricant 2, inclined installation, gravity to eliminate dew.
7, ultrasonic level meter why can not be used for high temperature liquid level measurement
Solution: High temperature will form fog into dew condensed on the liquid level meter probe, which will affect the ultrasonic transmission and reception, thus affecting the measurement results, often appear full scale alarm or other alarm situation.
8. Why is the ultrasonic level meter not suitable for measuring the liquid level with higher pressure tank equipment
Solution: High pressure acts on the surface of the transducer, resulting in sound waves that cannot effectively radiate, and even microwaves cannot radiate out. Ultrasonic wave and microwave belong to the radar series products, due to principle reasons, under high pressure, ordinary power can not work. But increase the power to do special treatment, ultrasonic can still work, but that cost is too big.
