    Are you wanting a one point indication?...a two point indication (high and low)?...a continuous level display (empty to full)? And, what is "RS."?

    RS = India's Rupee.
    $1 USD ~= 45.5 RS
    100 RS ~= $2.20 USD

    Stick a cheap yardstick into the vessel until it hits bottom. Read the level where the stick emerges from the water. Done. You can send me the balance if you have anything left from your budget. ;)

    So you're asking for a water level indicator that costs less than about 5 USD. Get some cheap vinyl tubing and make a homemade sight glass.

    If you want something electrical, you can take a look at how the water level is measured in RV water tanks (on-off resistance type detection).
