Hedland MC Series

Metal Body, Variable Area Flow Meter for Air and Other Compressed Gases. Replaces the EH55-D

The Hedland MC Series of pneumatic variable area flow meters are low cost and industrial class. These in-line flow rate indicators are designed to monitor pressurized air and other compressed gases. The Hedland MC Series features rugged metal body construction that is relatively insensitive to shock and vibration.

The Hedland MC Series is offered in seven port sizes from 1/4" to 3" for flow ranges from 0.5 to 2200 SCFM. These flow meters have a temperature range of -20 to 240°F (-29 to 116°C).

Variable area flow meters from the Hedland MC Series are available in aluminum, brass, and stainless steel. The stainless steel flow meters are pressure rated for 1,500 psi/103 bar maximum with a 10:1 safety factor. Aluminum and brass products are pressure rated for 1,000 psi/69 bar maximum (250 psi/17 bar maximum for 3" series) with a 10:1 safety factor. Brass meters are highly recommended for air systems with high water content or for systems where galvanic corrosion may be a problem.

Multi-Pressure Scale

This simple, direct reading flow scale features a vertically graduated scale, calibrated for air (1.0 specific gravity @ 70°F) in standard cubic feet/minute (SCFM). It also displays a horizontally graduated series of pressure levels (range lines) calibrated from 40 to 130 PSI.
