Oscilaltion detects the change of liquid level, and accuracy of detection is easily influenceed by buoyancy, repeatable accuracy is poor.Different liquid manure liquid needs
Recalibrate.It is not suitable for that accompanied with sticky is big, or impure liquid, easily causes ball float blocking, while different liquid manure
The use of liquid, liquid manure liquid can be caused to pollute.
The content of the invention
The purpose of this utility model is to provide a kind of liquid level wireless detection means for liquid manure machine.
In order to solve the above-mentioned technical problem, a kind of technical scheme of the present utility model is：It is a kind of to be used for the wireless of liquid manure machine
