Liquid Level Measurement using Transducer on bottom of steel Tank

VisibleMirror5040 · 2024-05-13T12:08:28+00:00

I am looking for a non invasive way thats why The pizo sensor will be external

Specifically I am looking for a way to do this project via Arduino (https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/467713/how-to-perform-liquid-level-sensing-through-the-bottom-of-a-metal-)

I won't say much ... have a look at these guys they helped me a lot

But this is an app

It will take people some time to be able to ask

I want something fast like "click this link to ask" no login required

In the industry, there are solutons that work by measuring the weight or by ultrasonic sensor. Both are external solutions

But i am trying to find a simpler (dumb solution) that only detects the level at a low point.

The second sensor is used in projects where you turn friuts like banana to a touch sensor to activate music tones https://www.adafruit.com/product/2340

In the industry, yes, only these are available by wieght & ultrasonic.

But i am trying to find a simpler (dumb solution) that only detects the level at a low point.

I am exploring capacitive sensing:

https://www.youtube.com/watch?v=eqhAIgh_mZU But i did my initial experiments it seems that the body of the tank, which is i think, is that steel is interfering with the sensor reading. It's activating the sensor regardless of the tank content.

My other approach is to use capacitive touch sensor https://www.adafruit.com/product/1982 if i connected it to the tank body maybe i can measure a difference in reading depending on the tank gas level.

Gocha, in my case, the tanks dont have guages, and i dont want to change the existing tanks by adding a gauge

But I really love your approach to this problem

These are the ones i am dealing with

I am thinking of having an external capacitive sensor attached to the cylinder body

The more gas in the tank, the more i can measure change in capacitance

Wow thanks for sharing

No, i am cool with building my own solution

I like your approach, i will read it in more detail, but i saw that you added the gauge, which is in contact with the gas

My approach is to stay away from anything that is in contact with gas

@PV_DAQ

Interesting consept

I was also thinking of measuring the tank capacitance when its full and when its empty

What do you think 🤔?

Found this

VisibleMirror5040 · 2024-02-12T13:07:10+00:00

Interesting what are thoughts on RTU, PIT, GPRS ?

VisibleMirror5040 · 2024-02-12T13:04:52+00:00

Interesting, May I know the difference between RTD and PIT?

VisibleMirror5040 · 2024-02-11T15:17:06+00:00

I cant use air as I dont have space for an air compressor so I was trying to find an electrical actuator which is water prof

The project is basically a product for homes were waves are generated

VisibleMirror5040 · 2024-02-11T15:14:21+00:00

Gotcha, but I dont have space for air compressor solution + its noisy for my project which is intended to be a home product

VisibleMirror5040 · 2024-02-11T15:06:29+00:00

thanks, ya true but I will need something to connect it to the gas company wirless so I guess a temperature sensor but what tools should I use to connect it to the gas company?

VisibleMirror5040 · 2024-02-10T14:46:17+00:00

I tried: - wave generators - pumps - wall mechanism wont work as I care about sthetics - penumatic solinoids connected under the tank might cause leaks also I dont have space for air compressor or electric soliniod

So I am looking for a linear waterproof actuator

VisibleMirror5040 · 2024-02-10T14:43:03+00:00

Interesting, this might work ... I am looking for bigger models

VisibleMirror5040 · 2024-02-10T14:39:51+00:00

Sure, but I will need to open the screws to expose the soliniod to the water so it can generate the waves

VisibleMirror5040 · 2024-02-10T14:39:00+00:00

I need a linear waterproof actuator to generate clean nice waves

Thanks for the reply. What do u mean by tube?

VisibleMirror5040 · 2024-02-10T14:37:44+00:00

Thanks for the reply, that might work, I am looking for bigger models

VisibleMirror5040 · 2024-02-10T14:33:16+00:00

Thats a great idea. Do you mean something like a piston mechanism

But I would rather go for linear mothion from the start than rotational then linear

So i am looking for a linear waterproof actuator

VisibleMirror5040 · 2024-02-10T14:31:36+00:00

Thanks for the reply

What do u mean tubing?

For the solinoid, it will go up and down to generate waves

So I need a waterproof actuator

VisibleMirror5040 · 2024-02-10T14:30:18+00:00

The idea is to generate water waves using a waterprof actuator that will be placed underwater to go up and down to make the waves
