Description
Technical field
The utility model designs liquid level emasuring device field, especially a kind of liquid level ruler and liquid level emasuring device.
Background technique
In daily agricultural irrigation, water level is the important parameter of paddy growth, in order to which rice can preferably be grown, accurately
Water level be essential component part.
The existing level monitoring to Rice irrigation generallys use liquid level ruler, but between each scale of existing liquid level ruler often
Extreme influence can be caused to measurement accuracy there is a phenomenon where hanging water.
Because in consideration of it, special propose this utility model.
Utility model content
The purpose of the utility model is to provide a kind of accurate liquid level ruler of measurement and liquid level emasuring devices.
To achieve the goals above, a kind of liquid level ruler provided by the invention, the liquid level ruler include substrate, and the substrate is
Rectangle pcb board, and zero graduation and multiple Measurement scales are provided in at least one side of the pcb board；
The zero graduation is rectangular metal coating scale, extends to top from the bottom of substrate, and be close to the side of substrate
Setting；
The Measurement scales are rectangular metal coating scale, and each Measurement scales are close to the edge of zero graduation along one and substrate side
The parallel straight line spaced set in side；
Hollow out is configured between each adjacent Measurement scales and in the substrate between each Measurement scales and zero graduation
Water proof channel.
Preferably, the zero graduation is the gold-plated scale of rectangle.
Preferably, the Measurement scales are the gold-plated scale of rectangle.
Preferably, the two sides of the substrate of the liquid level ruler is symmetrically arranged with zero graduation and Measurement scales.
On the other hand, the utility model additionally provides a kind of liquid level emasuring device, the measurement member of the liquid level emasuring device
Part is above-mentioned liquid level ruler.
Liquid level ruler and liquid level emasuring device provided by the invention, have the following beneficial effects:
Using unilateral long zero graduation, keep the distance between each Measurement scales and zero graduation consistent, to guarantee each survey
Measure good conductive effect between scale and zero graduation；
It is designed between adjacent scale using the channel of appropriate distance, makes that water will not be hung between two adjacent scales, also not
It can be because hypertelorism leads to the decrease of conductive effect, to realize the real-time of water level detecting, accuracy, reliability.Tradition
Electric water gauge water level will lead to actual liquid level and have fallen to certain Measurement scales, but also have liquid due to not having channel design
The Measurement scales for the side of being connected thereto；Or the Measurement scales of top have liquid to be connected to zero graduation, lead to conditional electronic water gauge water
The liquid level that position detects is higher than actual liquid level, and whether real-time, accuracy or reliability be not high.And it is set using channel
After meter, between adjacent Measurement scales, there is channel segmentation between each Measurement scales and zero graduation, does not have liquid connection, this
Real-time, accuracy, the reliability of sample detection have guarantee.
Detailed description of the invention
Fig. 1 is liquid level ruler structural schematic diagram provided by the utility model.
In figure:
1. 2. zero graduation of substrate, 3. Measurement scales, 4. water proof channel
Specific embodiment
Referring to FIG. 1, the utility model provides a kind of liquid level ruler.
The liquid level ruler includes substrate 1, and the substrate 1 is rectangle pcb board, and the actual size of the PCB can be according to reality
Border needs to be designed and select.
Zero graduation 2 and multiple Measurement scales 3 are provided in at least one side of the pcb board.
The liquid level that the quantity of the Measurement scales 3 monitors according to actual needs is adjusted, and the utility model does not do this
It is specific to limit.
The zero graduation 2 is rectangular metal coating scale, extends to top from the bottom of substrate, and be close to the side of substrate
Setting.
In the present embodiment, the zero graduation 2 uses the gold-plated scale of rectangle.Zero graduation can be improved using gold-plated scale
Inoxidizability and corrosion resistance, to improve the reliability and service life of liquid level ruler.
The Measurement scales 3 are rectangular metal coating scale, and each Measurement scales 3 are close to the edge of zero graduation 2 along one and base
The parallel straight line spaced set of bottom side.
In the present embodiment, the Measurement scales 3 use the gold-plated scale of rectangle.Zero graduation can be improved using gold-plated scale
2 inoxidizability and corrosion resistance, to improve the reliability and service life of liquid level ruler.
Further, zero graduation 2 and Measurement scales 3 are symmetrically arranged on the two sides of the substrate 1.With further
Improve the reliability, service life and measurement accuracy of the liquid level ruler.
In order to avoid the extension water between each scale, between each adjacent Measurement scales 3 and each Measurement scales 3 and zero
The water proof channel 4 of hollow out is configured in substrate between scale 2.
The considerations of being routed for each Measurement scales in substrate, in the present embodiment, the length of each Measurement scales 3 is from institute
Top to the lower part for stating liquid level ruler successively increases, corresponding, and the length of the water proof channel 4 between each Measurement scales also successively increases
Greatly, and the length of water proof channel 4 be greater than Measurement scales 3 adjacent thereto length.
The utility model additionally provides a kind of liquid level emasuring device, and structure and working principle please refers to existing liquid level and surveys
Measure device, which is characterized in that the measuring cell of the liquid level emasuring device is above-mentioned liquid level ruler.Measurement mould with the liquid level ruler
Block and monolithic mechatronics, and single-chip microcontroller and terminating machine communicate to connect, measurement data is timely uploaded to terminating machine.
Liquid level ruler and liquid level emasuring device provided by the utility model, by between zero graduation and Measurement scales be arranged every
Flume avoids between each scale because of liquid connection caused by hanging water, makes real-time, the accuracy and reliability of level detection
It is guaranteed.
Meanwhile each scale uses gold-plated scale, strengthens electric conductivity, inoxidizability and corrosion resistance, improves entire
The reliability and service life of liquid level ruler and liquid level emasuring device.
Specific case used herein elaborates inventive concept, the explanation of above example is only intended to
Help understands core of the invention thought.It should be pointed out that for those skilled in the art, not departing from this
Under the premise of inventive concept, any obvious modification, equivalent replacement or the other improvements made should be included in the present invention
Protection scope within.
