Hello Guys, Thanks for all the suggestions and Sorry for the late reply. I did go through the concepts of all your replies and found the transmission method most suitable to use. I tried the circuit and kept the transmitter and receiver at diametrical ends and again there was no echo to be...

It is a standard 15.6 Kg tank. Weight sensor's I've already calibrated and got the readings too. Then i started searching for other methods that would be possible to implement.

Power constrains are low. I did think about a thermal principles and tried to apply the hot water through the sides in an engineering perspective. Thermal sensors and heating etc would require good amounts of power and it seems to be impractical at this point.

Hey there guys, I'm an electronics engineer who just finished the course. I'm from India and as we Indians say, we decide what to pursue after doing an engineering degree. I have got job offers from companies such as Deloitte in their consulting division. But recently I joined a startup in the...

I will try that out. Thanks. Do you know about any sensor or application that could help measure sonic reflectivity?

Weight is the easiest method I agree, but I was looking for a non invasive tech that doesn't use weight as the principal measuring meter.

Okay, The sensor I'm using is an HCSR04 ultrasonic distance sensor that uses a 40KHz wave. I've been trying to get it penetrate the Cylinder by placing it on its surface first. The echo returns back in no time. I've been thinking of using an impedance matching agent such as a fine gel but there...

Hey guys, I'm an engineering student from India. Presently I'm involved in some Rn D projects and it requires a lot of help with theoretical concepts and practical applications. So there's no better place to be! Glad to be here and looking forward to some informative and fun discussions. Thanks

Hey guys, First time poster here. Presently I'm doing a project to measure the levels of LPG remaining in an LPG cylinder. I'm currently trying out ultrasonic sensor that primarily works as a distance sensor(HCSR04). As far as I'm aware, the lower the frequency higher the penetration of the...
