Non-contact discharge measurement for open rivers and channels. – Comfortable all-in-one system with integrated data logger and GPRS / GSM communication.
FEATURES AND ADVANTAGES
- Integrated data logger
- Integrated GPRS / GSM communication
- Contact free measurement, maintenance free system
- No structural work is necesary in the water
- No threat to the system through flooding
- Low power consumption enables operation using solar cells
- Recognition of flow direction
- Measuring range from +/- 0.10 to +/- 15 m/s (depending on the flow conditions)
- Recognition of hysteresis-effects
- Measurement in backwater situations
- Measures even where weed growth prevails and sensor is not affected by turbidity
- Measurement in tidal waters
