Liquid level controller online shopping with Drurylandetheatre? 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.
The advantages of ultrasonic liquid level gauge are very outstanding. It is mainly reflected in the following aspects : The structure is simple. The reading is convenient. It is very easy to install and maintain. Of course, the ultrasonic liquid level gauge also has its own limitations and insurmountable defects. Specifically, it is mainly manifested in: Ultrasonic liquid level measurement is easily affected by temperature. In the actual measurement, the change of temperature will cause the change of sound speed. This will lead to errors in the measurement.
Due to the non-contact measurement, the measured medium is almost unlimited. It can be widely used to measure the height of various liquid and solid materials. The ultrasonic liquid level transmitter is composed of three parts: ultrasonic transducer, processing unit and output unit.

The External Ultrasonic Tank Level Sensor adopts the sonar echo ranging principle. It overcomes the influence of the tank wall on the transmission of ultrasonic signals. It adopts advanced digital signal processing technology. It can truly realize non-contact, high-precision measurement of the liquid level in the tank. The External Ultrasonic Tank Level Sensor can output 4-20mA standard signals or output the measurement results to the upper computer (or secondary meter) through the RS-485 interface. It can meet the automatic control of the system.
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. 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.
