High quality ultrasonic tank level measurement online store? 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: There is a blind spot in the ultrasonic liquid level measurement. The dead zone is the area where the meter cannot measure. During the transmission of ultrasonic pulses, a small area near the ultrasonic transducer usually cannot receive sound waves. The blind zone where sound waves cannot be received is related to the measurement distance of ultrasonic waves. Generally speaking, the smaller the measurement distance, the smaller the blind zone. The larger the measurement distance, the larger the blind zone.
In the measurement, the ultrasonic pulse is emitted by the sensor (transducer), and the sound wave is reflected by the liquid surface and then received by the same sensor or ultrasonic receiver. Through piezoelectric crystal or magnetostrictive device into electrical signals. The distance between the sensor and the measured liquid surface is calculated by the time between the transmission and reception of sound waves. See more info at ultrasonic tank level measurement.
For spherical tanks equipped with a calibrator. The calibration sensor is installed at the center of the calibrator on the outer wall of the tank. If the calibrator is not installed, the calibration sensor should be installed at the height of the outer radius of the tank (equatorial zone). The calibration sensors for the vertical tank and the process tank are installed on the outer side of the tank body, at a height of 0.5m to 1m from the tank bottom. Note: After installing the calibration tube (calibrator) in the tank, the correct installation position should be marked with paint on the outside of the tank wall in time.
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. The sensor of the external liquid level switch couples the generated high-frequency ultrasonic pulse to the container wall through the couplant.
