Absolute rotary encoder gathers signal and is compared respectively, to avoid the occurrence of larger error.
In a kind of above-mentioned float-ball type level measurement device, in addition to controller and comparator, described main absolute type
Rotary encoder, secondary absolute rotary encoder and comparator are connected with controller, and main absolute rotary encoder and pair
Absolute rotary encoder can send data to controller respectively, and controller sends data to comparator and is compared.
In a kind of above-mentioned float-ball type level measurement device, in addition to the alarm and display being connected with controller,
And controller is sent data to after comparator is compared, data difference is shown by display, and when data difference exceedes
During controller setting value, described controller control alarm equipment alarm.
Therefore can display error directly perceived, and provide alarm when error is larger.
In a kind of above-mentioned float-ball type level measurement device, described ball float is fixedly arranged above locating rod, and described is flat
Platform is provided with the positioning hole being vertically arranged, and locating rod activity is located in positioning hole, and the chain between drive sprocket and ball float
Bar is parallel with locating rod.
Locating rod plays positioning ball float and moves up and down effect, avoids ball float or so skew from producing error.
In a kind of above-mentioned float-ball type level measurement device, described locating rod is provided with scale.
And it can also intuitively show water level using the scale in locating rod.
Compared with prior art, the utility model has the following advantages that：
The present apparatus can accurately calculate and converse water level value, and the present apparatus utilizes main absolute rotary encoder and secondary absolute type
