Surface water measurement system

The surface water measurement system OFW-GPRS is a stationary measurement system for non-contact water level
measurements using radar or ultrasonic sensors, including data loggers and remote data transmission technology - ideal
for early warning systems. The system can be combined with the “K1 camera” to visualize the current situation on site.
