Creating Water Level Detector using NI LabvIEW 2015, Water Level Detector in LabVIEW, How to create a water level detector in LabVIEW 2015, Water level detector using LabVIEW 2015, how to build water level detector in LabVIEWHello friends! Hope you all will be absolutely fine. Today I am going to share my knowledge with you about how to create an algorithm for Water Level Detector in LabVIEW 2015. LabVIEW is an excellent software for simulation purpose as well as for the hardware interfacing (interfacing with the external devices). I support the “Graphical Language” which is usually known as “Field Programmable Gate Array (FPGA) ” based language. In other software we have to create logic first and then we need to write a complete syntax for the created logic. This software is very easy to use and is quite helpful. Because, we don’t have to write the complete complex syntax, instead we have to just create our logic and implement this logic using FPGA blocks. In this tutorial we will learn to make a simple water level detector in LabView. The simulation is given below for download and if you guys have any problem in it then ask in comments and I will resolve them. This simulation is tested on LabView 2015.

Water Level Detector in LabView

Here I am going to elaborate you that how to make a simple Water Level Detector in LabVIEW 2015. First of all we will look at the important LabVIEW components or you can say tools, required to design a water level detector. You can see the list of these components below

  • Tank
  • Vertical Pointer
  • Upper Level Indicator
  • Lower Level Indicator
  • Graph to observe the results

You can download this simulation of Water Level Detector in LabView by clicking the below button:

Download LabView Simulation

Vertical pointer is used to control the level of the water in the tank. Upper level indicator shows when the tank is about to completely fill. Lower level indicator shows indication by turning “ON” the LED when the level of the water in the tank is too low and we need to fill it. Graphs shows the graphical visualization as the vertical pointer moves up ow down.

  • Go to the “Front Panel” and press “Right Click” from your personal computer or laptop.
  • Now, go to the Controls-> Modern-> Numeric-> Tank.
  • By doing this, you can see the following figure in your PC’s screen.

  • You can see different blocks in the above figure
  • Select the encircled “Tank” and place it on the “Front Panel”
  • It looks like the below figure

  • Now, put the “Cursor” on the tank and press “Click” you can see that the water level changes with each different click on the tank
  • You can see the above step in the figure below:

  • Blue color show the level of the water in the tank.
  • Now go to the “Front Panel” and then go to the Controls-> Modern-> Numeric-> Vertical Pointer.
  • By doing this, you can see the following figure in your PC’s screen:

  • You can see different blocks in the above figure.
  • Select the encircled block i.e. “Vertical Pointer”.
  • Place this block on the “Front Panel”.
  • It is looking like the figure below:

  • Put the “Cursor” on the “Vertical Pointer”, press click and then move up and down.
  • It looks like the figure below:

  • Blue color indicates the value or rate at which we want to fill the tank
  • So now, you have selected both the tank and the vertical pointer and you can see that it looks like the figure below:

  • Now press “Ctril+T”
  • You can see the “Block Diagram” window is looking like the below figure

  • Now, since we want to control the level of the water in the tank with the help of the vertical pointer by adjusting it at different positions
  • So, we have to build a connection between them
  • Take a wire from the output terminal of the vertical pointer (Slide) and connect it to the input terminal of the tank
  • The figure below exhibits the above steps

  • No we have to set the upper and lower level for the less and high amount of water indication
  • We need to put two LED’s, one for the upper level ndication and the second for the lower level indication
Upper Level Indicator
  • Press “Click” on the “Block Diagram” window
  • Go to the Functions-> Programming-> Comparison-> Greater or Equal?
  • Figure displays the above steps

  • Select and place this block on the “Block Diagram” window
  • Connect its first input terminal with the output terminal of the “Vertical Pointer”
  • Go to the second input terminal of the “Greater or Equal” press “Right Click”
  • Go to the Create->Constant
  • The figures below displays the above steps
