Chongqing Chuanyi HS-AW Series Ultrasonic Level Meter

The Chongqing Chuanyi HS-AW Series Ultrasonic Level Meter represents an efficient and cost-effective solution for non-contact level measurement and process automation. Operating on the time-of-flight acoustic principle, the transmitter’s piezoelectric transducer emits sound waves downward toward the target medium. The built-in microprocessor calculates the exact distance based on the time elapsed between transmission and echo reception, converting it into a stable level or volume output.

Advanced Acoustic Signal Processing In industrial and municipal water applications, surface turbulence, environmental noise, and false echoes from tank walls often challenge level instruments. The HS-AW series integrates sophisticated echo-processing algorithms and filtering technology to accurately identify true surface reflections while ignoring background interference. This ensures high measurement reliability under difficult operational conditions.

Non-Contact and Maintenance-Free Design Because the transducer never makes physical contact with the measured medium, the HS-AW series is entirely immune to corrosion, scaling, and chemical attack from aggressive liquids or wastewater. This non-contact nature eliminates mechanical wear and significantly reduces routine maintenance requirements, making it an ideal choice for long-term continuous operation.

User-Friendly Integration and Operation Equipped with intuitive local configuration interfaces and standard industrial outputs (such as 4-20mA signals with optional communication protocols), the instrument connects effortlessly into existing Distributed Control Systems (DCS) and Programmable Logic Controllers (PLCs). Its flexible mounting options allow for quick installation on tank nozzles, open channels, or bracket supports.

FAQ

Q1: How does the ultrasonic level meter maintain accuracy during temperature changes? A: The HS-AW series features a built-in temperature sensor that automatically measures ambient air temperature within the vessel and compensates for the speed of sound, ensuring continuous precision.

Q2: Can the ultrasonic meter be used for open channel flow measurement? A: Yes, when configured with appropriate parameters and combined with standard weirs or flumes, it can accurately calculate and monitor open channel flow rates.

Q3: Are there any media limitations for ultrasonic level measurement? A: Ultrasonic meters require a clear acoustic path. They are ideal for most liquids and wastewater, but heavy foaming, extreme steam, or heavy suspended solid layers may absorb acoustic signals and affect performance.

Q4: Does the sensor require physical contact with the liquid? A: No, it is a completely non-contact instrument, meaning the transducer is mounted above the maximum liquid level, avoiding wear, corrosion, and fouling.
