Express ADCP Configuration

Express ADCPHigh quality data / low total costof ownership.TELEDYNE RD INSTRUMENTS MARINE MEASUREMENTSExpress ADCP ConfigurationNow, even on a limited budget, you can experience thequality and proven benefits of a Teledyne RD InstrumentsBroadband Acoustic Doppler Current Profiler(ADCP)—backed by our legendary worldwide customerservice and support.The Express configuration, priced 30% below ourWorkhorse family of ADCPs, is ideally suited for basiccurrent profiling applications. As your needs progress,the Express can easily be upgraded to include the fullspectrum of Workhorse flexibility and product features.For moored current profiling applications withoutdemanding requirements, the Express configurationmay be an ideal, economical alternative to our WorkhorseADCPs. The Express Sentinel is designed tosatisfy the needs of scientists, engineers and managerswho must reliably collect low-noise current profiles,with a limited number of depth cells, from stationaryplatforms like bottom mounts or buoys, using an internally-recording,self-contained instrument.Data Quality: The Express Sentinel includes anabbreviated menu of operational choices whileretaining TRDI’s hallmarks of unmatched Broad-Band data quality and ADCP reliability.Accuracy: The Express Sentinel provides anaccuracy of 0.8% with temporal update rates of 5minutes (minimum).Upgradable: As your needs change, the ExpressSentinel can be upgraded to a standardWorkhorse ADCP, providing you with the capabilityfor moving boat surveys, directional wavemeasurements or the ability to quantify turbulenceparameters.

The pressure sensor allowsthe ADCP to dynamically adjust the placement of the waves array so that it is as close to the surface as possible,providing improved high frequency response.
