Snow Level Monitoring

In cold winter, by leveraging LoRaWAN-based snow level monitoring solution, government departments can take timely response to heavy snowfalls and avoid confronting with long-time road restriction. The EM500-UDL-C050 ultrasonic distance level sensor can help create a network that helps improve field visibility and makes a city smarter.

Snow Level Monitoring

Tank Level Monitoring

Measuring tank levels in industrial applications is a difficult task to carry out with repeated accuracy and reliability. We can continue to take use of the inexpensive traditional stick made of wood, metal or plastic and inspect it by our sense, but it’s labour cost and easy to error-making due to the manual reporting methods.
