In locations with large temperature changes, such as: strong sunlight, it will cause measurement
errors. This error will increase by 2-4% based on the original measurement accuracy. Please install a
sun visor to solve it.

Large temperature change-add sun visor or meter box
If the distance between the probe and the highest position of the medium is smaller than the dead
zone of the meter, the measured values are all wrong.
④
The minimum distance to the medium is less than the dead zone
If the sensor is installed too close to the container wall, a strong false echo will be generated. The
uneven inner surface of the container wall, the adhered medium, the rivets, screws, stiffeners and
welds on the container inner wall will cause strong false echoes and load on the effective echo signals.
So please note: Keep the distance between the sensor and the container wall according to the
maximum distance you need to measure. See the table below for details.
⑤ The sensor is too close to the container wall

For more severe measurement conditions, continue to increase the distance between the sensor and
the container wall until no false echoes appear.
