Flow Rate Meter
Selection Guide

In some applications, simply measuring the amount of water actually used is good enough. In others, you also need to know the actual rate of flow in order to calculate time to fill or time remaining with current supply at a current flow rate, or even to monitor pump performance. Below is a list of all of the flow meters offered by Assured Automation that will measure and display instantaneous flow rate, or real-time flow rate.
