Starflow Ultrasonic Doppler : Unidata
6526C
For water flow monitoring in open channels, streams and large diameter
pipes, the new Starflow Model 6526C is a unique combination of water depth
and velocity sensors combined with a fully featured 120k Data Logger and
software.
- Battery powerered for use in remote locations
- Operates in water qualities from fresh water streams to primary sewage
- Measures forward and reverse flow conditions
- Programmable to compute flow in pipes and open channels
- Rain Gauge input channel
- Flow Proportional sampler control
- Compatible with modems
