Product details

Product introduction

Performance characteristics

1. High measurement accuracy, wide range, can measure weak current and strong current;

2. Sensitive sensing, high resolution, not limited by the starting flow rate;

3. Fast response speed, can measure instantaneous flow rate and average flow rate;

4. The measurement is linear and there are no K and C values of the calibration curve;

5. There are no mechanical rotating parts, and there are no problems such as sediment blockage or entanglement of water grass and sundries. It is most suitable for measurement in rivers with high content of suspended sediment, many floating objects such as water grass and extremely harsh ice age.

Function introduction

1. Mini handheld host is convenient for users to carry and measure;

2. Large screen LCD display has continuous background light function;

3. Built in complete clock, convenient for users to calibrate and query time;

4. Equipped with data reading software to realize data storage, printing and output functions;

5. Real time display of instantaneous flow rate, average flow rate, instantaneous flow rate, average flow rate and water temperature;

6. The measurement mode is divided into automatic measurement and manual measurement to meet the needs of different occasions.
