Product Highlight: IF-IOL Series IO-Link® Converter
Many facilities still rely on proven 4–20 mA and 0–10 V analog sensors for critical measurements. While these signals remain widely supported, integrating them into modern digital architectures can introduce unnecessary complexity, particularly as systems scale or require more granular diagnostics.
The IF-IOL Series IO-Link® Converter is designed to bridge that gap. By converting legacy analog signals into IO-Link® process data, the IF-IOL Series enables existing sensors to participate in a standardized, bidirectional digital communication framework without requiring sensor replacement or extensive rewiring.

Variable Area Flow Meter Corrections Getting Accurate Readings from Variable Area Flow Meters Most variable area flow meters are factory-calibrated for air or water at standard conditions (70 °F and 14.7 PSIA). But when real-world pressure, temperature, or gas type changes, the reading can drift from the true flow. To correct this, apply two simple formulas: one to account for pressure and temperature changes, and another for gas specific gravity. Together, they convert the indicated flow to actual standard flow. DwyerOmega’s Series VF, VA, and Rate-Master® RM flow meters deliver reliable measurements when paired with proper correction—helping you maintain accuracy across any application.
