radar level meter

1. Causes of inaccurate display value of radar liquid level meter
1. See if the power is working
When the radar level of the liquid level to a certain value after the change
is very slow, should check the power supply, whether the normal power,
whether the normal output after power. When there is no change in the
liquid level, it is necessary to check whether the fuse of the equipment is
fried, if there is no current output, then there is a problem with the
instrument
2. Using rising and falling temperatures
In order to ensure the measurement effect, the internal temperature
of the radar level gauge should be less than 50 °C. If the internal
temperature exceeds this value, a small amount of wind can be blown
to the instrument head, the scientific temperature. Avoid using ice
water for cooling, ice water not only can not achieve the role of
cooling,but also may lead to radar level meter paralysis
3. The display value is not accurate
The inaccuracy of display value is a common problem of radar level
gauge, which may be caused by improper initial setting or incorrect
connection of plug-in Then to check in detail whether the radar level
gauge output current is normal, inspection found that the output current
is greater than 22 ma, then is the display module failure. If the output
current is less than 3.5 ma, the electronic module is out of order

2. 4. The system displays error messages
When the system often displays error information, need to reset and
calibration, the reason is because of data storage process suddenly
power failure. If there is no change after reset and re-calibration, the
electronic module of the radar level gauge needs to be checked
5. Antenna contamination, crystallization
When the radar level meter due to antenna contamination, crystallization
of the failure, the need to clean the antenna, power off, remove the
instrument tilt down, wipe with a cloth to remove the attachment, do not
scratch with iron, do not bend the antenna, pay attention to handle
gently, so as not to damage the ANTENNA'S SKIN
Thanks in advance.
