Query Water Velocity in FluidFlux

Hello everyone. I’m wondering if anyone has a straightforward way, or tutorial on how to query water velocity data from a river created using FluidFlux. So here is the deal. I have a river I have created. I want the player to be able to place a handheld sensor in the river and read velocity data at each point where the sensor is placed. I have a grabbable water sensor mesh with a collision capsule on the end that will be place in the river. It has an lcd that I want to display the velocity readings on the other end. My problem is figuring out the best way to accomplish this using blueprints. I am learning as I go. Finding exactly where to call this data from is also proving difficult. Thanks for any help.
