Tips: What is ultrasonic level sensor?
The ultrasonic level sensor uses the time difference between the transmission and reception of sound waves and the propagation speed of sound waves to calculate the liquid level. The ultrasonic level sensor using non-contact measurement technology can be stably and reliably applied to continuous liquid level measurement in various open liquid/solid/powder tanks. Ultrasonic liquid level sensor is a very ideal measurement tool for corrosive, layered or acid-base wastewater. The media that can be measured by the ultrasonic level transmitter include industrial agents such as hydrochloric acid, sulfuric acid, hydroxide, waste water, resin, paraffin, mud, lye and bleach.
ATO ultrasonic level sensor has the following characteristics:
- Simple structure, convenient reading, convenient installation and maintenance, high cost performance, low maintenance cost.
- The use of corrosion-resistant materials, safe and clean, long life, high precision, stable and reliable.
- Non-contact measurement is less affected by the viscosity and density of the liquid.
- There are various ranges to choose from (0.5m~60m range), which can be applied in different industrial environments.
- It has an RS-485 communication interface and adopts a special echo processing method to effectively avoid false echoes.
Ultrasonic level sensor has integrated structure and mainly consists of LCD display, ultrasonic probe and waterproof connector. Ultrasonic level sensor can be used for non-contact level measurement of various medium, such as liquid (water/fuel/oil), solid (metal or nonmetal), or powder (chemical materials), etc. The measuring range can be from 0-5m, 0-10m, 0-15m, 0-20m to 0-60m. The output signal can be 4-20mA or RS485/232. Ultrasonic level sensor also has optional power supply DC 24V or AC 220/50Hz.
