External ultrasonic level gauge

Thread Content

I. Product Overview The intelligent external-mounted level gauge (hereinafter referred to as the level gauge) utilizes advanced signal processing technology and high-speed signal processing chips, overcoming the influence of tank wall thickness to enable accurate, contactless measurement of the liquid level in enclosed containers. The ultrasonic sensor (probe) is installed directly below the outer wall (bottom) of the container to be measured; no holes need to be made in the container, installation is simple, and it does not interfere with production. It enables accurate measurement of the liquid level of various toxic substances, highly corrosive materials, and various pure liquids inside high-pressure sealed containers. The level gauge has no special requirements regarding the liquid medium or the material of the container; it features an explosion-proof design that meets safety standards, allowing for wide-ranging use. II. Functional Features: Non-contact measurement – The ultrasonic sensor (probe) is magnetically attached to the outside of the container, eliminating the need to make any holes in the container being measured. ● Automatic calibration function: The level gauge features an auto-calibration function, which overcomes the problem of reduced accuracy that occurs in traditional level gauges after long-term use. ● Exceptional measurement stability: Compared to other ultrasonic external level gauges available on the market, this transmitter utilizes a specialized stabilization algorithm that incorporates advanced optimization techniques and artificial intelligence to ensure high measurement stability. ● Extremely small measurement blind zone: Taking water acoustic waves with a speed of 1485 m/s as an example, the blind zone is generally 0.2 m to 0.3 m; the blind zone is even smaller when measuring chemical materials with low sound speeds. ● Infrared debugging function: A convenient infrared debugging function, especially suitable for situations where it is not appropriate to open the device for debugging in hazardous environments ； It also reduces the difficulty of debugging. ● Self-diagnosis function: The level gauge has a function to diagnose its own operating status, as well as a hardware diagnosis function ； This increases the reliability and stability of the level gauge. ●One-click recovery function: When the level gauge malfunctions, it can be restored to normal operation with just one click using the debugger. ● Local display and remote transmission function: The level gauge allows for easy display of the liquid level value on-site, and it can also transmit this data to the control room via a communication interface. ● OLED displays are diverse; the on-site display of level gauges can have various parameters adjusted using a remote control, replacing the need for laptop-based debugging. III. Working Principle: The level gauge uses specialized ultrasonic processing technology as its core, enabling ultra-fast processing of digital signals. The measured liquid level height values are accurate. After obtaining the liquid level value, the CPU can send it to the DSRAM for storage or to the display screen for on-site display. In addition, the instrument can output a 4–20mA standard signal, or it can transmit the measurement results to a DCS or secondary meter via RS-485 (MODBUS protocol standard) and HART interfaces. IV.
