- Floatless level switch
Unlike ordinary level switches that use a float for level detection, the 61F Floatless Level Controller uses electrodes to electrically detect the liquid level
The Level Controller would automatically operate the pump, to control the liquid level in the tank.
Floatless are used in two different way
1) they are used to protect the pump from getting burnt in case the water levels are low only in the borehole, well and ground or surface tank
2) to control the pump that is filling the overhead or upper tank.

The best electrician youtuber ive ever seen.. Really liked your content..love from malaysia♥️♥️
Thank you so much 😀
Explanation clear. Thanks for this video. I have been trying to understand the operation of this device but after watching this video I got the principle now
Best electrical info technology systems and audio explain is the best way for sharing this information
Keep up continue with your video and company
Great video, nice work. I'm truly grateful for the knowledge u r sharing. I pray for wisdom as u share more videos 🙏🙏
Thank you, I will
Gracias, me sirvió mucho. Thanks!!
Thank you so much for sharing the wonderful videos. Am learning a lot
You are so welcome!
Thank you for clearing some questions i had , now i understand.
You are most welcome
Understand very well thanks 👍
You are welcome
thanks allot, I really appreciate your effort 🙏
Thanks for being a good teacher 👍👍👍👍
It's my pleasure......Thanks for watching
solved my problem. thanks
Very good and simple Video ...Tq
Welcome 😊
thankyou sir again for another advanced knowledge
Great thanks
Good teaching
Thanks and welcome
Thanks again for sharing your knowledge I will definitely trying myself because I am learning to become an electrician since I don't any practice only theory # tuko pamoja
Excellent 👍
Thank you
Good explanation
Thanks for liking
Can you do a video on solonoaid valve for controling water in high rising buildings
Thanks!
Welcome!
Niceee 👍🏽
Good demonstration.
Thanks for the video Q; your 110V power source, ls that connected directly into a wall receptacle? Do you have 110V where you are? looks like you're using a transformer
Hey there I am loving your videos it’s really helping me. I have a large septic tank with is lengthier but it’s not wider so I want to use 2 float switch to a motor how can it wire the float switch so that when they both are up the motor should start and when both are down motor should stop,can you please make a video on it I would be delighted. Or you can reply too
Hey there thanx for watching..........this video has the answer to your question,.... but let me explain
1) get a contactor (rate it with your pump),
2) get a float switch,
since you want the float switch to control your pump, connect it in series to the contactor coil to the supply........ Then use the main contact of the contactor to connect the motor.
The second option is this video, try to understand it.
if you cant come back to me.
@@electreca1 but in my country floatless switch are not available so can you suggest any other alternative's through which I can connect 2 float switches
the secondary voltage according to the face plate is 8 VAC. Presumably that is the voltage sent to the sensor rods?
Thanks for that explanation.You are really helping out.But can use both NO and NC simultaneously or I can only use one at a time.Your response will be highly appreciated....
You can only use one at a time....because also you use all the contacts to control only either NC or NO.
You are the best..... Thank you very much brother man....
kindly the live wire that is connected to A1 are we tapping it from E1??..... thankyou
You sending electricity in the cup (12v) ?
the great
ls the 8 VAC sent to the NC / NO ? Was my assumption wrong two comments down? l don't own a voltage meter. Maybe i should buy one?
Thanks. This was really good. What type of relay is that?
Floatless pin relay
Thanks alot
Tq sir, but I still not understand well, regarding the function of relay indicator, I mean the red light indicator..what the indicator try to tell us...pls explain..
Thanks for this video. Please in real installation, what will be used as the electrode?
There already made electrode that are sold in the market, but Earth rods(coper) can work fine.... coper is a good conductor but not sure if can resist corrosion since it will be Merced in water.
Thank you ,is it the same for three phase submersible pump ?
Yes, it's the same.
i had to wire this exact relay for a chiller. just out of curiosity. what will happen if you take out the earth probe but put in the E2 and E1 probe ?
There might be a risk of electric shock, though not high
hello here's another question, Q: l want to operate a small hydronics pump 110V Vevor type RS 15-6 which is 3-speed (manually dialed) & rated i@(low speed/mid speed/high speed), i(amps) 0.42 / 0.60 / 0.84 with power rating P(Watts) 46 / 67 / 93 respectively in a non-pressurizing plumbing loop. Lowest speed has tested adequate for my purpose. High speed for priming. lf i understand correctly, l should be able to power the pump directly from the C61F directly without using the intermediate SSR. Do you concur? l will be bench testing anyway at all speeds which means l might anticipate a burnt out float switch if my estimation is incorrect. Thanks for the visual aids
So it simply means if I am using a big three phase pump, E1,E2 and E3 will pass through the NO open of the contactor, then to the pump ?
E1,E2,E3 activate the floatless relay, then floatless relay operates the contactor coil.
What am not understand those e1-e3 is it a pump inside water
Hello can you use D.O.L or Star Delta starter with floatless switch pls
For DOL yes
@@electreca1 your already upload vid?
Thanks sir I have a submersible motor I want make auto matic if the water is high because in my house flood kid there's no submersible motor can I ask you a diagram for this?
@SUNDU Am trying to undrestand your question but i cant. please ask again.
@@electreca1 I have a magnitic contactor with overload how to attach this for floatless sir that's my point
@@electreca1 thanks for your response sir
Thanks for the explanation. I want to use the sensors inside a borehole well that is 120 meters deep. Will the sensors work at that dept? I read somewhere that if DC voltage is used, the electrodes might corrode. Is that true and what's the remedy? What's the maximum distance that those sensors can be far apart in the well?
Yes, it will work up that depth...........it can even work at 400mtrs.
Your well is 120mtr deep, even if the control box is 200mtr apart its ok(but we all know you can't apart CB for 200mtrs right!!).
NOT wire that used to connect the probs are not ordinary, you have to buy the right one for that purpose.
@@electreca1 Thank Electreca. When I talked bout the electrodes and their recommended maximum distance apart, what I meant was the sensors. Those two or three sensors that actually get submerged in the water. How far apart can they be? What's the maximum permissible distance for which they may be apart for them to still be operational and still send appropriate signals to the control box.
Then you didn't answer the question on if the sensors can corrode because they transmit electric current.
I look forward to your response. Thanks
The floatless I used in this video is of 3 electrodes.....
First, you have to know the water rest level of you well...
Position E3 on the same level as the draw pipe or submersible pump, if the resting level is 6mtrs ...you will position E3 at least a metre above the bottom, E2 2mtrs from E3 and E1 1mtr from E2...
So that means that your pump has a pumping area of 2meters if water goes below 2 meters the control power goes off. these Numbers are not fixed can be altered depending on how deep is the resting level.
But to determine all that accurately
Note the following
1) how many CUBIC meters that you're well can give per minute
2) how big is the head of your pump
Because their scenario were your pump takes more water than what you well can produce.
Op that helps
@@electreca1 Thanks. Can I use two sensors instead of 3? If yes, how will that affect the wiring to the relay and contactor?
@@electreca1 Can the sensors corrode as a result of them carrying electricity (perhaps due to some kind of electrolysis)? If yes, how can this be avoided?
What the hell, you just put 220 or 120 v direct in the water, this is not the right way, and you probably use salt water to do this trick, bcs i made the original sensor systam motor on of circuit,
i might be wrong but i dont think the probes carry any current. if it did i should have shocked a long time ago. i think the probes just give continuity to a sensor or something.
