Need to know when a liquid or gas is flowing - or when it's not?

The status, stability - even the safety - of processes can depend on whether operators know for sure whether or not a liquid or gas is flowing. PVL has the flow indicators and the know-how to make sure that your operators are never in the dark about flow.

Take a look below at the PVL range of flow indicators you'll find them with a floating ball, bright yellow paddles, Pelton wheels, 360-degree view, switches, and various accessories. You'll see flow indicators for dark liquids, for high temperatures and for high pressures. In fact you will find a flow indicator for just about every application in the book.
