The Teledyne ISCO Model 801 EM Current Meter, 6 m Cable (604480211) is a handheld electromagnetic wading set for measuring water velocity in open channels, shallow flows and confined spaces. It combines a single-axis flat sensor, 6 m cable, 1.5 m wading rod set and logging Control Display Unit with a measurement range of -5 to +5 m/s.
Key Features
- Bidirectional -5 to +5 m/s velocity range, supporting measurement of positive and negative water flow
- Verified measurement accuracy, specified at ±0.5% of the reading plus 5 mm/s
- Compact flat sensing volume, measuring approximately 20 mm in diameter × 10 mm high for shallow or confined flows
- Minimum water depth of 5 cm, supporting measurements where conventional current meters may be unsuitable
- Real-time readings updated at 1 Hz, with velocity displayed at a resolution of 1 mm/s
- Adjustable averaging from 1 to 600 seconds, with fixed, moving and free-running averaging modes
- Standard deviation display, helping operators assess flow variability and measurement stability
- Internal storage for up to 999 averages, supporting field data collection before transfer to a computer
- RS232 data transfer, with a PC interface cable and licence-free CDUExpress software supplied
- Logging Control Display Unit, sealed to IP67 and powered by eight alkaline C cells for up to 37 hours
- Six-metre sensor cable, equivalent to 20 ft for extended reach between the sensor and display unit
- Sectional 1.5 m wading rod set, comprising three graduated 0.5 m rods with a base and direction knob
- Complete field package, supplied with the flat transducer, CDU, interface cable, operating manual, transit case and rod carrying bag
- Factory-calibrated sensor and CDU system, with calibration performed up to a water velocity of 1 m/s
Note: Measurements above 1 m/s are based on linear extrapolation unless a specific high-speed calibration is arranged.
Benefits
- Enables water velocity measurements in shallow channels and restricted locations using the low-profile flat sensor.
- Supports field measurements in either flow direction across a broad velocity range.
- Improves confidence in averaged results by displaying the associated standard deviation.
- Reduces manual recording through internal logging and transfer of stored results to a computer.
- Provides a portable, self-contained wading package for open-channel surveys and environmental monitoring.
- Allows the averaging method and measurement period to be adjusted for different flow conditions.
