In-Line Sight Meters

Product line includes over 10,00 in-line variable area flow meters, designed to monitor oil, phosphate ester, water and water-based emulsions, air and other compressed gases. Hedland offers flow meters constructed of high-performance materials including: Anodized Aluminum, Brass, and Stainless Steel. The Hedland meters are easy to install, operate in any position (no flow straighteners or special piping needed) and are accurate to ± 2% of full scale.

Aluminum meters are offered as a rugged, low cost flow meter for monitoring non-corrosive water-based or petroleum-based fluids in flow ranges up to 300 GPM (1100 LPM) and pressures up to 3,500 psi (241 bar).

Brass models are recommended for water systems or other applications where galvanic corrosion could become a problem. Brass meters are rated to withstand pressures up to 3,500 psi (241 bar), and are available up to 150 GPM (560 LPM).

For higher pressure systems we recommend T303 Stainless Steel models, and for corrosive or caustic fluids, we recommend T316 Stainless Steel meters. These meters can withstand pressures up to 6,000 psi (414 bar) with flow ranges up to 150 GPM (560 LPM).

The standard flow scale for liquids is calibrated in GPM and LPM at .876 specific gravity for petroleum, 1.18 s.g. for phosphate ester, 1.0 s.g. for water and water-based emulsions, 1.0 s.g. for air and compressed gases. Special scales are also available in other units of measure or specific gravities. The pneumatic meters are offered with a unique multi-pressure flow scale, calibrated to indicate flow rate, in standard cubic feet per minute (SCFM), or liters per second (LPS), at various pressure from 40 to 130 psi (3 to 9 bar).
