Reg-Sensor

DhanushAdhavan

Hi all I'm searching for the sensor to measure the weight of the water inside the water bottle and one request is that sensor size to be a small be as to fix at the bottom of the water bottle.

Water bottle Spec: 0.5 litre or 1 litre water bottle

For example: if i fill water into bottle as a 0.5 litre I have to show that 500gram of water ..and for ur notice that reading is not an issue I can connect that via any application but the main thing I need here is I have to measure it. and if further info need means kindly let me know guys.

kindly help me with this guys.

Thanks in advance.

    ya thanks much for ur answer but i need a sensor to know how much of water inside the bottle 

    and for calculation purpose ur answer is helpful Slight smile

    Wink My thought was to show how to think about which method you should use and how much effort you can put into it.

    ) One method would be with a defined balloon that has a strain gauge on the outside. When water is poured in, it expands and you can convert and deduce the amount.
    Because a bottle made of a solid material is not optimal for weighing.
    ) -> unless you do it using the method I suggested earlier.

    ) So if you want to fill the water directly into a bottle, then an optical sensor would be possible, which detects the reflection of the water.
    This would require a defined and correspondingly calculated bottle that has a reflective strip on the back.
    A beam of light shines through the bottle, which is deflected by the water level depending on the filling height.
    If the light is no longer detected by the sensor, then the water's edge has been reached there. You can read the water level on the scale on the bottle and convert it to the amount.

    ) At the bottom in the bottle there may be a pressure sensor. The weight of the water presses on this sensor.
    But there must be a sensor in the bottle here.
    Weighing the whole bottle is then a bit more complex, because the weight of this built-in sensor has to be subtracted.

    ->> Such bottle you can buy in a "house held" shop, which can have 1 litre or more.

    ) Ultrasonic sensors would be one possibility, sending them into the bottle from above, the corresponding echo that comes back can be converted to the volume.
    Here, too, a corresponding effort is required.

    What accuracy do you need? There are resistive pressure sensors that might be suitable for simple low accuracy measurement.
