PORTABLE ELECTROROMAGNETIC VELOCITY METER

The PVM-3i is a portable electromagnetic current meter designed for all types of flow velocity measurement surveys, including sewage, wastewater, stormwater, and rivers. Its sensor probe shape is not affected by suspended matter, and the sensor body has a built-in earth, so it can be used while installed at the bottom of a pipe. Additionally, an optional data transfer kit allows measurement data to be imported into a PC.

Main function

1. Automatic sensitivity adjustment according to flow velocity
2. Real-time display of flow velocity values
3. Measurement data saved in internal memory
4. Automatic power saving mode
5. Saved data can be transferred to a computer
6. Built-in calendar
