Doable?!

Former Member
Former Member over 10 years ago

I am just getting into the Raspberry Pi scene so forgive my ignorance - how difficult would it be to write code that could take a distance measure (maxSonar) in mm and convert it to volume (ounces remaining). I have this hairbrained idea to try and monitor fluid levels in my beer keg or hot liquor tank. Yes I am aware of flow meters - just have the sonar on hand from a friend that I can use. Any suggestions would be greatly appreciated.

    It appears your range finder has a 4-20mA output, in which case you will require an ADC input to measure the distance and then eventually resolve that into volumetric measurement. The rPi does not have…

    RaspberryPi may be a bit of overkill for this application - perhaps an arduino would be simpler... Using a MaxSonar With an Arduino Arduino Playground - MaxSonar

    Application Specific. Different applications require different ultrasonic sensors. We design our processes to manufacture ultrasonic sensors by the thousands. It’s that simple. Engineers and OEMs value our factory calibrations because once a product is selected they can move forward with their large-scale deployment without manually configuring each individual sensor.

     

    Key Characteristics

    • Simple Mounting
    • Low Power Requirements
    • Select from Multiple Outputs
    • High Reading Stability
    • Calibrated Beam Patterns
    • Additional features on each product page

    Featured Applications

    • People Detection
    • Remote Bin Measurement
    • Automated Store Displays
    • Water Level Measurement
    • Parking Sensor
    • More Applications

    Although it could work, it depends on which one you choose. See LV-MaxSonar-EZ Quick Start Guide for some understanding. By far the best discussion is here If you have the one your friend gave/lent above, it is very doubtful.

    Hope this helps,

    Clem
