1. Product Introduction

The FP111/FP211/FP311 portable direct-reading flow meter is used to measure the flow velocity in open channels and non-full pipes. The flow velocity probe consists of a protected water turbine propeller positive displacement sensor connected to a retractable probe handle; it is primarily used for stormwater runoff studies, measuring flow velocity in sewers, pipes, ditches, rivers, and monitoring water bodies in streams. The handle is made of anodized aluminum, which is lightweight and has a long service life.
