ADC

Designed specifically for in-stream velocity measurement, the ADC features a sensor with two 6 MHz acoustic transducers, temperature and depth sensors, and a cable and handheld unit for signal processing.

Usage Type: Spot
Measurement technology: Acoustic
Parameters measured: Flow velocity, depth
Product Highlights: Latest state of the art ultrasonic Doppler technology for high accurate velocity measurements. Maintenance free sensor with integrated depth measurement, graphical step by step user guidance and discharge calculation according to ISO 748 and USGS standard
Measurement range: -0.2 … 2.4 m/s
Accuracy: ± 1% of measured value ± 0.25 cm/s

Features
  • Innovative Technology– Accurate velocity measurements using the latest acoustic technology and automatic discharge calculation based on international standards (USGS and ISO 748)

  • High Performance– 6 MHz acoustic transducers and large sample volume reduce potential signal-to-noise issues
  • Time Saver– Built-in depth sensor and measurement guidance minimizes time in the field and reduces sources of measurement error
  • Simple Setup– Logical menu structure and large buttons help facilitate quick and easy setup
  • Easy-to-Use– Review instantaneous velocity and measurement quality data during the measurement with the rod-mounted graphical display
  • Versatile– Supports USGS, ISO, ICE, KREPS, and multi-point velocity methods and Mid and Mean section discharge methods
  • Flexible– Attaches to common wading rods like the USGS Top Setting wading rod
