Ultrasonic level switch is installed outside the tank. No need to open holes in the tank. Non-Contact Measure. The ideal choice for tank level monitoring.

HS-ULC Ultrasonic Level Switch-External Mounted

Ultrasonic Level Switch, External Mounted (referred to as “external level switch”) is a new type of level measurement alarm device. Ultrasonic Level Switch is mainly used to detect the liquid level of the storage tank. It can realize the upper and lower limit alarm or monitor whether there is liquid in the pipeline (dry protection). The material of the storage tank can be various metals, non-metals or non-foamed plastics. The wall thickness can be Up to 70mm.

Ultrasonic Level Switch is not affected by factors such as medium density, dielectric constant, conductivity, reflection coefficient, pressure, temperature, precipitation, etc. It is suitable for various liquid levels in the pharmaceutical, petroleum, chemical, electric power, food and other industries Engineering control. Ultrasonic Level Switch is the ideal choice for the detection of toxic, highly corrosive, and dangerous liquid level.

Sino-Inst offers a variety of Radar Level Transmitters for level measurement. If you have any questions, please contact our sales engineers.

HS-ULC Ultrasonic Level Switch is specially used to measure the liquid level of tanks. Because it is installed on the outside of the tank, there is no need to punch holes, which is widely welcomed by customers.

Of course, if your tank already has holes, you can also choose other tank level transmitters.

The ultrasonic principle can also be used to measure water depth. Please refer to Portable Ultrasonic Water Depth Gauge for water depth measurement.

Ultrasonic Level Switch Working Principle

Ultrasonic Level Switch Working Principle

The sensor of the external liquid level switch couples the generated high-frequency ultrasonic pulse to the container wall through the couplant.

The pulse will propagate in the container wall and liquid, and will be reflected by the inner surface of the container.
By detecting and calculating the characteristics of the reflected signal, it can be judged whether the liquid level has reached the position where the controller is installed.

The liquid level controller can output a relay signal to facilitate the detection and control of the liquid level.

Float Level Sensors & Switches

The float level switch is a kind of level switch. The float level switch uses magnetic force to operate. No mechanical connections. The operation is simple and reliable. When the float switch floats the measured medium, the float moves the main body. At the same time, the magnet on the other end of the float will control the magnet on the switch action lever.

FAQ

What is ultrasonic level sensor?

Ultrasonic level sensor is a monitoring instrument for measuring liquid height, tank height, and material position. The ultrasonic level sensor can adopt two-wire, three-wire or four-wire technology.
The two-wire system is: power supply and signal output are shared.
The three-wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24v power supply, a 3-core cable can be used, and the negative terminal of the power supply and the negative terminal of the signal output share a core wire.
The four-wire system is: when using AC 220v power supply, or when using DC 24v power supply. When the power supply loop and the signal output loop are required to be completely isolated. A 4-core cable should be used.
DC or AC power supply, with 4~20mADC, high and low switch output.

What does a level switch do?

The function of the liquid level switch is to control the liquid level. For example, the water pump fills the pool with water, and the level switch can make the water in the water tank neither overflow nor empty, and there is always water. “

Can ultrasonic sensor detect water level?

The ultrasonic sensor can of course measure the water level.
When the ultrasonic level gauge is working, the high-frequency pulse sound wave is emitted by the transducer (probe), and is reflected on the surface of the measured object (water surface). The reflected echo is received by the same transducer (probe) and converted into an electrical signal . The time between pulse sending and receiving (the movement time of the sound wave) is proportional to the distance from the transducer to the surface of the object. The relationship between the distance S of the sound wave transmission and the speed of sound C and the transmission time T can be expressed by the formula: S= CⅹT /2
In addition to using ultrasonic level gauges for water level monitoring, users can also use radar, depth water level sensors and other technologies to monitor water level.
