Description
Technical field
The present invention relates to liquid measure field, more particularly to a kind of liquid level alarming switch detection method based on static liquid level
And its scaling method of alarming line.
Background technology
For the detection method of liquid level alarming switch, detection in the prior art is mainly by manually moving liquid level
Standard of the float of alarm switch as detection, and the scaling method of liquid level alarming switch alarming line, are first to open liquid level warning
The float of pass is put into liquid, and using the sink-float degree of float as foundation, liquid level line is drawn on float, then by manually moving
The float of liquid level alarming switch uses distance-measuring device to the position just alarmed（Typically use ruler）Measure the liquid of float
The distance between bit line and reference-calibrating face, the calibrating parameters as liquid level alarming switch alarming line.
Using manually moving detection method and its alarm of the float of liquid level alarming switch as liquid level alarming switch
The scaling method of line, it is impossible to which intuitively embodiment float floats over the situation on liquid level；And by first drawing liquid level line, then measure alarming line
Demarcation mode, on the one hand add the pilot process of demarcation, its measurement result is unreliable, on the other hand in manual mobile float
When, stability is poor in its moving process, easy deflection or imbalance, another further aspect due to the individual difference of liquid level alarming switch,
The sink-float degree of its float in a liquid, which differs, establishes a capital the same, and various reasons are so as to causing measuring result error value very big.
The content of the invention
The purpose of the present invention is the deficiency corresponding to prior art, there is provided a kind of liquid level warning based on static liquid level is opened
Close the scaling method of detection method and its alarming line, its can intuitively detect liquid level alarming switch whether can normal work,
And in the case where that need not control changes in liquid level, the present invention being capable of accurate scale liquid position alarm switch alarming line
Position, precision is high, easy to operate, quick, substantially increases detection, the efficiency of demarcation.
The purpose of the present invention is realized using following proposal：A kind of liquid level alarming switch detection based on static liquid level
Method, include being used to drive the vertical of liquid level alarming switch vertical lifting to be detected using following liquid level alarming switch detection means
