How to use a Propeller flow meter?

When using a Propeller flow meter, first, check the appearance of the instrument for any damage. Ensure that the battery has sufficient power and check the calibration certificate. Calibrate the instrument if necessary. Then, carefully install the propeller on the sensor and make sure it is firmly installed and can rotate freely.

Next, place the current meter at the position where the flow velocity needs to be measured, such as in a river, canal, etc. Try to keep the instrument perpendicular to the direction of the water flow. When measuring in deep water areas, use an appropriate measuring rod to lower the current meter to the specified depth.

After that, turn on the power switch of the instrument and select the measurement mode according to the prompts on the operation interface. The instrument will automatically collect data. The data collection time can be set from 30 seconds to several minutes depending on the actual situation to ensure the accuracy of the data.

After the measurement is completed, the water flow velocity data will be displayed on the instrument screen. Record the data in a timely manner, and also record relevant information such as the measurement time, location, and water depth.

Finally, turn off the power of the instrument after the measurement is finished. Carefully remove the propeller and store the instrument and the propeller properly to prevent damage from collisions. It should be noted that there are differences in the operation details of Propeller flow meters of different brands and models. Be sure to read the instruction manual carefully.
