$FLOW is an ERC-20 utility token of Velocimeter which is a solution for protocols on Canto to properly incentivize liquidity for their own use cases. Building on top of the groundwork laid out by Solidly, our team has addressed that first iteration's core issues to realize its full potential. $FLOW is used for rewarding liquidity providers through emissions.
Velocimetry is the measurement of the velocity of fluids. A velocimeter is a tool that is used to measure fluid dynamics. We felt this is analogous to what is happening in our AMM & gauges; "Liquidity" is added, moved around, and "flows" in and out of it.
