Thanks for this video. Very well explained about what is water sensor, their types and how does it work. Working principle of water level sensors- 1. Level sensors are put into a certain depth in the liquid to be measured. After putting these sensors into the liquid, the pressure on the sensor’s front surface transfers into the liquid level height. 2. The calculation formula for measuring the level of liquid is- P=ρ.g. H+Po. 3. Here, P stands for Pressure on the liquid surface of the sensor, ρ stands for the density of the liquid to be measured, g is for local acceleration of gravity, H is for depth at which sensor drops into the liquid and Po is the atmospheric pressure on the liquid surface.
Hi,,,I am locating s sensor to installl at the end point of the pipe line,once the TR pump will run to fil the tank so sensor should sense the water availibilty in line,and if in between somewhere line got brusted ,so sensor should give us alaram
I need a switch that detects low water level and turns on a pump to open the valve to let water in to fill it up to a certain level, what should i use?
Hello and thanks for your question! In order to choose the correct level sensor/switch for your application you'll need to determine some factors such as how much power can be supplied, how is the sensor going to be mounted and does the valve require DC or AC voltage to operate?

Hey, although the transducer type he has in here is very useful, you could also go with an electro-mechanical old fashioned method. The old method uses a floating bobber in a cylinder with a mechanical switch at the top (the kind you find in old joysticks). You could use a fishing bobber and a mechanical switch. You put those inside a pipe with a slit cut down the side(so you can see it). This was how my old swamp cooler from the 80s worked. It was hooked up to the garden hose. They used a "custom" floater, but anything which floats is fine. The buoyancy will make pressure against the switch to tell you when it is full. Otherwise, it is always on. You might ask, how do I make it turn off by activating a switch? Well, the answer is you hook it to a relay. relays have NO(normally open) and NC(normally closed). You hook the switch to the coil of the relay. You hook the filling switch to the NC line. When the water is full, the switch turns the relay on, and to the current goes to the NO pin, and turns off the NC pin, thus turning off your device. The only thing left is to check first that there IS POWER at all, or else it will stay on and flood everything. For this you hook power for the coil(on 2nd relay) directly to power input, then NO circuit to the switching relay. That way if there is no power, nothing happens. So all you need for this circuit is a resistor, ,2 relays and one switch. Very old fashioned, but it(the old swamp cooler) worked in a wet environment for 25 years(then my dad sold it on for the same price he bought it). Hope that helps.
@@sudhakarjadhav3146 U want measure water level on the road. Water level will not be too high . Maybe u can put sensor in street light then u must use high quality ultra-sonic sensor. For exlaple u put sensor on street lamp. u need measure 400cm-water level(2or3(max?)). if you want to measure with light you can use floating plate in case. Case can fill with water on the road.
Hi Ernie, our engineering specialists would love to help. Go to the support section on our website www.Omega.com and we can walk you through what you need via phone or chat.
I'm thinking of the same sorta thing. I will use a float on a lever, and on the other end of the lever, a copper terminal and another copper terminal away from the lever slightly. This should work as long as the copper-copper contacts don't ware significantly. All the best with your work!

Sir please tell me can we use this ultrasonic transducer to indicate level of water on road in rainy season ,please give reply
yes u can bu u should take hq sensor.
It needs to measure 2-3 cm from 3-4 meters
@@batuhansengulme can you please explain briefly
