The Liquid Level Controller is attached to the outside of the tank. Non-contact detection of tank liquid level. Liquid Level Controller supports liquid level alarm, fault alarm, and 485, Modbus, 4-20mA, FoundationFieldBus, PROFIBUS or Hart.
Liquid Level Controller is installed outside the tank. The HS-ULC-Pro Liquid Level Controller works based on the principle of ultrasonic waves, and is also called “externally attached liquid level switch. It is mainly used to detect the liquid level of the storage tank, and its sensor (digital probe) acts on the outer wall of the storage tank. It supports upper and lower limit alarms, tanks Body temperature display or monitor whether there is liquid in the pipeline. Liquid Level Controller is suitable for liquid level process control in the pharmaceutical, petroleum, chemical, electric power and other industries. For the monitoring of toxic, highly corrosive and dangerous liquids, HS-ULC-Pro Ultrasonic Non-contact Liquid Level Controller is an ideal choice.
Features of HS-ULC-Pro Ultrasonic Non-contact Liquid Level Controller
- Advanced signal processing methods. Can overcome the influence of temperature drift. Stronger anti-interference
- Brand new installation method. Adsorption type + adhesive type. Can improve the stability of the probe
- Built-in temperature sensor. Monitor temperature changes for 24 hours. Temperature compensation is also possible

HS-ULC-Pro Liquid Level Controller Working Principle
The sensor of the High-Pro type liquid level controller couples the generated high-frequency ultrasonic pulse to the vessel wall through a couplant.
The pulse propagates in the wall of the container and in the liquid. It will also be reflected by the inner surface of the container. By detecting and calculating the characteristics of the reflected signal.
The measured data is transmitted to the on-site secondary meter through the 485 serial port in real time. It can be judged whether the liquid level reaches the position where the controller is installed.
Liquid Level Controller
You may ask What is a liquid level controller?
Wikipedia does not give a professional definition of liquid level controller.
We define the liquid level controller as follows:
Liquid level controller refers to the control of high and low liquid levels through mechanical or electronic methods. It Can control solenoid valves, water pumps, etc. So as to achieve semi-automation or full automation. There are many methods, depending on the choice of different products.
The common liquid level controllers are as follows:
1.Floating type liquid level controller
The float type liquid level controller is composed of a magnetic float, a measuring tube, a signal unit, an electronic unit, a junction box and installation parts. Generally, the specific gravity of the magnetic float is less than 0.5, which can float on the liquid surface and move up and down along the measuring tube.
A measuring element is installed in the catheter. It can convert the measured liquid level signal into a resistance signal proportional to the change of liquid level under the action of external magnetism. And convert the electronic unit into 4-20ma or other standard signal output.
2. Displacer level controller
The Displacer level controller changes the magnetic float to a float. Displacer level transmitter uses tiny metal film strain sensing technology to measure liquid level, interface or density.
Such as Fisher DLC3010 Digital Level Controller
3. Hydrostatic liquid level controller
The hydrostatic level controller works by using the measuring principle of hydrostatic pressure.
Generally, a silicon pressure sensor is used to convert the measured pressure into an electrical signal. Then it is amplified by the amplifier circuit and compensated by the compensation circuit. Finally, it is output in 4-20ma or 0-10ma current mode.
