Liquid Level Controller monitors the liquid level of tanks and sends out control signals. Upgraded liquid level switch. Upper and lower level alarm. Tank temperature display or monitor whether there is liquid in the pipeline.
Liquid Level Controller is an ideal ultrasonic Non-contact Liquid Level switch. The sensor is attached to the tank body. No need to open holes in the tank. 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.
Sino-Inst offers a variety of Liquid Level Controllers for level measurement. If you have any questions, please contact our sales engineers.
Features of Ultrasonic Non-contact Liquid Level Controller

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.
Liquid Level Controller can also be used with paperless recorder.
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.
Of course, the above is the working principle of this product HS-ULC-Pro Ultrasonic Non-contact liquid level controller.
There are other types of liquid level controllers on the market. The liquid level switch controller is a pressure sensor that measures liquid level. It is divided into contact type and non-contact type. We make a simple introduction to the measurement principle:
Liquid level control system for oil and gas
Through node sensors such as wireless temperature sensor + thermometer, wireless pressure sensor + pressure gauge and wireless liquid level sensor + liquid level gauge, the temperature, liquid level, pressure and other parameters of the storage tank are collected.
Upload to the wireless data collection gateway via 2.4G, 433MHZ wireless.
The gateway processes the data received from the wireless sensor node.
Provide data to the XL.VIEW server through the RS485 serial port, so as to monitor the production status of the storage tank and handle the limit alarm.
When the temperature, pressure, and liquid level of the storage tank are abnormal, the intelligent measurement and control device automatically drives the sound and light alarm to remind the staff.
Solution for real-time remote monitoring of liquid level, pressure and temperature of natural gas and oil storage tanks:
- Wireless temperature sensor
- Wireless pressure sensor
- Wireless liquid level sensor
- Wireless data collection gateway
- Intelligent measurement and control terminal
The storage tank remote monitoring system is suitable for real-time monitoring of the safety of the storage tanks of various chemicals such as gasoline, solvent oil, isooctane, mixed aromatics, isobutane, liquefied petroleum gas, natural gas, etc.
