Measuring system for continuous evaluation of flow velocity and flow direction in tunnels.
Ultrasonic sensors for tunnel ventilation control system. Reliable measurement across the tunnel profile.
Two identical sensors alternately transmit and receive ultrasonic pulses. The system evaluates the transition times dependant on direction and calculates flow speed. D-FL 220T requires extremely low maintenance.
stand-alone system, no control unit required
simple configuration
corrosion resistant against aggressive tunnel atmosphere
sensors can be replaced quickly, no tools, no re-alignment required
signal transmission
- per 4-20mA analog signal and 2 relays
- per RS 485 bus via MODBUS RTU protocol
minimized spare requirements
extremely low maintenance
