Consider the impact of temperature:

Reason: The speed of sound is affected by temperature. Although most modern instruments have built-in temperature compensation, extreme temperature or temperature gradients can affect accuracy.

Suggestion:

Ensure that the instrument operates within the allowable ambient temperature range.

Avoid installing in direct sunlight or near high-temperature equipment, and install a sunshade.

For high-temperature liquids, using an extended tube (submerged tube) can lower the temperature at the probe and reduce the impact of steam.

Dealing with steam, foam and dust:

Steam: A large amount of steam absorbs and scatters sound waves. The use of extension tubes can effectively isolate.

Foam: foam will absorb sound waves, causing serious signal attenuation. For light foam, try to adjust the transmission power or use a guided wave tube; It is recommended to use radar level meter for severe foam.

Dust: High concentration dust can also weaken sound waves. Ensure the probe is clean and regularly maintained.

Avoid vacuum or negative pressure environments:

Reason: Ultrasonic waves require air as a propagation medium and cannot propagate under vacuum or strong negative pressure.

Suggestion: Ultrasonic level gauges are not suitable for this type of working condition, and radar level gauges should be selected.
