Liquid Level Sensors for River Reservoir Monitoring
The 400B Series Transmitter is an independently developed solution for measuring liquid levels. It features a core sensor that incorporates a built-in diffused silicon element.
This device is designed with fluid dynamics in mind, showcasing an enlarged bottom filter screen for precise measurement of liquid height from the transmitter to the surface. It also includes a detachable bottom filter cover to prevent clogging, an internal air guide tube, and a triple-layer protection process. Compact in size, it delivers exceptional performance and cost-effectiveness, making it suitable for various harsh environments.
Every phase of our manufacturing process—from research and development to production assembly, calibration, and quality inspection—strictly complies with international quality production standards.
