Ultrasonic Level Meter

The LR725L Ultrasonic Level Meter adopts the wireless transmission principle without touching the measurement medium. The ultrasonic level transmitter uses the speed of sound waves to calculate liquid level. The high and stable measurement accuracy is owned by the constant speed of sound wave transmission. LR725L can measure liquid levels up to 50m. The products adapt to different industrial application scenarios' requirements, including corrosive and high-temperature liquids. MicroSensor LR725L non-contact liquid level transmitter is with simple installation and easy maintenance. It is widely used in industrial field measurement of liquids and slurries.
