New 'Side-Looking' Doppler River & Open Channel Flow Meter
OTT Hydrometry has launched a new acoustic doppler sensor system for continuous monitoring of flow velocity and water level (optional) in rivers and open channels.
The system provides reliable velocity measurements even in a flood situation with high sediment loads.
The OTT SLD (Side-Looking Doppler) is compact and easy to install and operate in rivers or open channels. It is available in three versions offering a velocity measurement range of up to + / - 10 m/sec for water bodies that are up to 80m wide, The SLD measures velocity by dividing the water body in to 9 independent â€˜cellsâ€™ with two horizontal beams looking sideways into the flow. The cell velocities are combined to give an average velocity for the section.
Data is recorded via RS232 or SDI-12 interface and when used in conjunction with the OTT LogoSens® multi-channel data logger the system becomes a continuous flow monitor. Discharge levels are calculated internally by the datalogger from water level and flow velocity measurements and can be transmitted via telephone, GSM or satellite to a central station.
The flow monitoring system is designed for very low power consumption, running on internal batteries with wind or solar charging options.
