I'm making a water level detector to control my motor which supplies water in water tank and for that I'm going to use ultrasonic sensor to be attached to tank lid. My question is whether the vapor arising from water inside the tank hamper the overall working of ultrasonic sensor and/or it may be damaged permanently. I can cover complete ultrasonic sensor using hot glue stick but cannot cover its diaphragm as it will block sound waves. Please suggest something.

Sto facendo un rilevatore di livello dell'acqua per controllare il mio motore che fornisce acqua nel serbatoio dell'acqua e per questo userò il sensore ad ultrasuoni da collegare al coperchio del serbatoio.La mia domanda è se il vapore derivante dall'acqua all'interno del serbatoio impedisca il funzionamento complessivo del sensore a ultrasuoni e/o possa essere danneggiato permanentemente.Posso coprire il sensore a ultrasuoni completo usando una colla a caldo ma non posso coprire il suo diaframma perché bloccherà le onde sonore.Si prega di suggerire qualcosa.

You may be able to find a data sheet for the usual in-air transducers giving humidity limits. You will not be able to seal them yourself without making them not work. Sealed ones do exist for vehicle parking systems, but require different electronics. Also beware minimum distances. – Chris Stratton16 set. 162016-09-16 19:30:20

For fluid level measurement you are best off using a capacitive fluid level sensor. – Majenko16 set. 162016-09-16 20:47:16

I'm not sure if there is even an issue here. But you could try out different types of plastic bags, to see which are 'transparent' to ultrasonic sound. Alternatively, just replacing the sensor every one or two year, wouldn't be that bad. Just make sure that your code accounts for a bad sensor (e.g. turn of the pump after 10 minutes regardless of the water level). – Gerben17 set. 162016-09-17 12:19:31

Plastic bag shields will not pass enough signal for the common sensors. – Chris Stratton20 set. 162016-09-20 12:42:08

I am posting an answer just because I do not have enough reputation in order to comment. This is not a straight answer but more like a workaround. Have you tried using the system from a toilet water tank? also, you could put a floating magnet inside the tank (and limit its x-y movement) and a reed switch (or more) outside of the tank at the desired levels. Another idea (not sure of it works, depends on the water quantity) is to place a barometer on the bottom of the tank and measure the pressure. – Virgil Litan20 set. 162016-09-20 17:04:25
