Inches water column (in WC)

Inches of water column is a unit of pressure mainly used in North America to measure small differences in pressure. 1 inch of water is the pressure exerted by a 1 inch high column of water at a given temperature. It can also be represented as in WC, inAq, inches water gauge, or in H2O. Air and other industrial gasses are often measured in inches of water when at low pressure rather than inches of mercury or pounds per square inch (psi).

The direct sealing diaphragm technology of Equilibar back pressure regulators offers unmatched precision for challenging pressure control situations including those in aerospace, research, catalysis, two-phase flow, cryogenic, biotech, and extreme temperatures.

Single Use Spotlight: flow control for WFI point-of-use systems

In modern biopharma manufacturing, water-for-injection (WFI) point-of-use (POU) control systems provide sterile, temperature-controlled water to be dispensed at a variety of locations throughout a plant. Many POU methods rely on level and mass measurements, which typically require operator oversight during dispensing. A newer option relies on flow measurement, which can streamline cleanroom processes and simplify Read More
