Q: How does the Direct Water Velocity Logger measure water current?

A: The velocity logger utilizes a remote data logging system based on hygrometer principles, capturing water current speeds via built-in sensors and recording them for future analysis. The devices LED display shows instantaneous velocity values, ensuring users can monitor measurements in real-time.

Q: What is the process for calibrating and storing data on the device?

A: Calibration is straightforwardsimply follow the included user manual to calibrate, with the logger capable of storing up to five separate calibrations in its 5KB memory. Calibration ensures accuracy and repeatability in all measurement sessions.

Q: When should I use this logger for best results?

A: This water current meter is ideal for deployment during field studies related to hydrology, irrigation management, and industrial flow analysis. It operates reliably in environments ranging from -40C to 75C, with optimal performance at its rated 25C measuring range.

Q: Where can this device be installed or used?

A: The loggers robust but lightweight construction and battery power allow for versatile installation at rivers, irrigation channels, industrial discharge points, and research sites. Its small size makes relocation and field portability simple.

Q: What benefits does the GPS feature provide?

A: Integrated GPS allows every measurement to be geographically tagged, which is invaluable for site-specific studies, ensuring precise data correlation and easy mapping for hydrological and environmental research.

Q: How long does the battery last and how can I maximize its standby time?

A: The device offers a standby time of up to 200 hours thanks to its efficient battery-operated design. To maximize this duration, power off the logger when not in use and operate within recommended temperature limits.

Q: What are the main applications for the Direct Water Velocity Logger?

A: This instrument is widely used in hydrology and groundwater studies, irrigation system evaluations, water resource management, industrial flow monitoring, and academic research, providing high-precision current velocity data where it matters most.
