Thông tin sản phẩm
- The OTT SLD is a measurement system for continuous measurement of water velocity and level in streams, rivers, and canals. The sensor employs the acoustic Doppler principle to reliably- measure flow velocity in a variety of naturally occurring conditions, including during most flood events.
- Equipped with two horizontal ultrasonic transducers "looking sideways" into the flow (Side Looking Doppler) to measure water velocity.
- An optional vertical transducer and integrated pressure cell measures the water level.
- All measurement values are analyzed, verified and processed by an integrated signal processor, before being used in the calculation of discharge.
- Velocity measurements from up to nine cells are used, along with measured water level, to calculate discharge either internally in the OTT SLD or externally in a data logger.
- All measurements can be retrieved using SDI-12, RS485 , RS232 or Modbus RTU protocols and are available for storing in a data collection platform, such as the OTT netDL station manager.
- Reliable performance in waters with high sediment load and flood situations
- Applicable in natural rivers, streams,  shipping-, irrigation- and service water canals
- Also suitable for small waterbodies (smallest cell size 20 cm)
