What is the use of relay in water level controller?
When the water level in the over head tank exceeds the required level, the pump automatically turns off and stops the pumping process thus preventing the over flow of water. It uses a relay to cut off the power supply to the water pump.
What is water level relay?
Description: This high quality liquid level control relay is specially designed for monitoring liquid level in pool, well, water tower, reservoirs, tanks, etc. You can set water draining mode and water supply mode, easy to operate.
Which sensor is best for water level indicator?
stainless steel probe sensors
The best sensor to use in a water level indicator is stainless steel probe sensors. Stainless steel sensors prevent rusting, fouling, and deteriorating due to poor water quality. For example, we only use stainless steel sensors in all of our water level sensors.
How do you make an automatic water level indicator?
To make this circuit you will need
- BC 547 Transistor X 3 = 9 INR.
- 220 K Ohm & 5.4 K Ohm resistors = 1.
- 1N4007 Diode = 1.
- 12V relay = 12.
- One, 3-pin PCD connector & two, 2-Pin PCB connector = 25.
- Wires = 5.
- PCB = 12.
What is level control relay?
Level control relays are regulators for conductive liquids that keep liquids within the limits between a maximum level and a minimum level and ensure the protection of submerged pumps against dry running.
How does liquid level control work?
How does a liquid level controller work? Level Controllers operate using a displacer, also known as a float, in the process fluid. As the fluid level passes the high-level set point, a signal, either electric or pneumatic, is sent to a control system or an automated control valve, also known as a dump valve.

Why bc547 transistor is used in water level indicator?
This indicates that the container is full. BC 547 is known as cheap and easy to use transistor which can be used to design a low-cost water level indicator. You can use this device in day to day life to detect the various levels in water in a container.
How does an automatic water pump controller work?
Basically, an automatic pressure controller is a motor that will automatically switch on when water in the overhead tank (OHT) falls below the lower limit and vice versa. The circuitry behind it is straightforward, minimising the potential for electrical issues, and it is very energy efficient too.
What is water level sensor?
What is water level sensor? Water level sensor is a device that measures the high or low level of a liquid in a fixed vessel. According to the method of liquid level measurement, there are two types of contact and non-contact.
What is a level controller?
Level controllers are automated units for measuring the level of fluid in a contained area. They’re used in systems that prevent liquid levels becoming excessively high or low.
What is Floatless relay?
Floatless relay FLR / FLRP series is a lineup of highly-reliable electrode liquid level relays that electronically detects changes in liquid level for control.
How does a Floatless level switch work?
Unlike ordinary level switches that use a float for level detection, the 61F Floatless Level Controller uses electrodes to electrically detect the liquid level.
What is float less switch?
Floatless Level Switch (Compact, Plug-in Type) 61F-LS
Consolidates the Specifications through Free Power Supply, thus Allowing Use in High Temperature Environments with Temperatures of Up to 70°C* * Excluding the DC power supply type.
What is the function of level switch?
A level switch is a sensor that detects the presence of liquids, powder, or granulated materials at a specific location. (It is also referred to as level sensor) For example, when a tank is supplied with liquid, it overflow.In order to prevent overflows, a level switch is installed near the top of the tank.
What are different types of level switches?
Level Switch Types
- Capacitive Level Switch. Capacitive level switches are designed to measure corrosive liquids, high temperatures, and liquid levels in sealed containers. …
- Conductivity Level Switches. …
- Diaphragm Switch. …
- Displacer Level Switch. …
- Float Level Switch. …
- Optical Level Switch. …
- Paddle Level Switch. …
- Tilt Level Switches.
What is difference between level switch and level transmitter?
Measurement: A level transmitter is perfect for a condition where the exact level of fluid needs to be measured. This is usually preferred for applications where precise measurement becomes a necessity. A level switch is an ideal choice for applications where extreme low or high levels need to be measured.
