Portable Flow Velocity Rate Meter: FM-210V6
The FM-210V6 Portable Flow Meter operates based on the velocity-area method. It measures the water flow velocity at different points within an open channel or pipeline using a rotating sensor. The rotational speed of the probe is converted into an electrical signal proportional to the flow velocity
It allows users to perform on-site, accurate, and repeatable flow velocity measurements even in complex field conditions. Data collected from the FM-210V6 can be used to calculate discharge rates, flow profiles, and current characteristics, supporting both routine monitoring and scientific research applications.
