WHY THE ELF PURGE METER IS POPULAR

The Model ELF purge meter is a compact, customizable flow meter designed for the measurement of small flows of liquids or gases. Custom materials, scales and scale markings for various flow applications are available at a competitive price.

Modular design principles allow users to specify body material, flow range and media, O-ring materials and optional hand knob. ESKO offers custom scale markings and calibration for non-standard liquids and gases.

The ELF is often paired with the Model EFR3 constant flow regulator also designed and built by ESKO for maintaining flows in applications where supply or back pressure varies. Metallic parts on the Model ELF are solid and reliable SS316 construction.
