Hi, I live in a rural area where the water supply works only a few hours weekly, and I use it to fill a 10.000 gallon tank.
I'm looking for a sensor that can measure the water level in the tank and send this info in a digital way to my computer so I can track and control the water usage.

I'll appreciate any sugestion. Thanks in advance for your help.

Victor

you can also use an ultrasonic sensor.

Dissolved impurities in water make it a conductor. The water sensor works by detecting low resistance between the terminals when wet.

I am trying to understand how United Security Products WLS water sensor works. Does anyone know how this device works internally? What does the internal circuitry works? What does the circuit that detects water actually works?

Thanks,

I've just completed building a 1200 gallon cistern. I put in three of these units to detect the water level (USP Water Level Sensor)
http://www.amazon.com/gp/product/B001HLAOX4

They all connect back to an Elk M1 Gold unit. The top sensor kicks on a sump pump to move water out of the cistern to 600 gallon rain barrels that I already had. It also announces that the water level is high. The second announces that the water level is half full/empty. The third opens a valve on the rain barrels to fill the cistern. I use the cistern as the main feed for a garden sprinkler system.

I need something similar that will let me know the level of water in my well.

OR you can use a SUNX Brand (Panasonic) EX-F1 Series
http://www.clrwtr.com/SUNX-Liquid-Detection-Sensors.htm

TURCK RU100-M18-LIX-H1141 list price - $738.10
Banner Engineering Q45ULIU64ACRQ6 list price - $$425

but SUNX EX-F1 is very cheap at $129.10 - list price compared to the other two choices given.

Hi Victor,
To measure the water level in your tank you could use an ultrasonic sensor with an analog output, 0-10Vdc or 4-20mA.
Examples of sensors are TURCK Sensor Type RU100-Q30-LUX-H1141,
Type RU100-M18-LIX-H1141. Or Banner Engineering Senor Type Q45ULIU64ACRQ6, Type Q45ULIU64BCRQ6.
To transform the analog signal to a digital signal you could use the TURCK Interface Module Type IM43-13-R, or Type IM43-14-Ri.
See also: http://www.turck.com and http://www.bannerengineering.com
The price for these items is rather high. You could try to buy them on www.ebay.com, or look for an electronic ultra sonic sensor kit to build yourself.
I hope this helps you out.
Frank

Please let me know if you got?I am also in the same problem.

Thanks



I am also looking for a water level indicator for my tank when it needs to refill it up. Have you got one already?
Jassu, I'm just wondering why the need for your aquarium. Does the water level goes down that low? What kind of aquarium is that?
