HZYW650 Intelligent Wireless Ultrasonic Level Transmitter


HZYW650 series intelligent wireless digital wireless liquid level/level sensor is a high-precision, high-stability intelligent digital display product launched by our company. It is suitable for real-time measurement and display of liquid level/material level. The product adopts a dedicated wide temperature LCD display, a high stability sensor, and is carefully manufactured through precision digital temperature compensation and nonlinear correction technology to ensure high accuracy and high stability of liquid level/level measurement. The built-in wireless module uses the network to provide users with wireless long-distance and low-power data transmission, and sends all the sensor status data to the cloud background management server in real time to achieve alarm linkage and data statistical analysis with the smart cloud platform.
