Overview
The Hedland H624-007 is a mechanical variable area flowmeter (rotameter) designed for direct-reading flow measurement in hydraulic and water applications. This used Hedland H624-007 unit features an integrated gauge dial and requires no electrical power or complex piping. It is ideal for test loops, condition monitoring, and flow verification in industrial systems.
