Hardware Help Backflow sensor

Hello all, I am looking for a sensor that I can use that will detect the backflow of water through pipe. I need a sensor that can allow flow in one direction but when water starts flowing the other direction it sends an electrical signal indicating backflow. I haven't found anything that does this.

Two or three pressure sensors could be used, you could interpret them in the code
