The Phosphate Ester Flow Meter is a Variable Area Flow Meter offering a low cost alternative for measuring heavier, solvent-based materials and lubricants. The superior weather-tight construction of this flow meter allows for use in outdoor environments and where wash-downs are required. By using a Pyrex® tube and special seals, this meter is compatible with more aggressive fluids. The standard selection of NPT, SAE, and BSPP ports reduce the number of adapters needed for an easy installation.
