Improving Environments For a Safer & Sustainable World

Pressure

Known for quality, reliability and accuracy, Dwyer designs and manufactures a full-line of Controllers, Data Loggers, Gages, Manometers, Monitors, Remote Displays, Switches, Transmitters, and Accessories to measure, monitor and control pressure, air velocity, flow, fan pressure, duct, and more.

Air Velocity

Dwyer offers Wind Meters that have the option of Pocket Wind Meters and handheld meters. There are also Wind Speed Indicators and Vaneometers that are designed to simplify the measurement of low air velocities. Air Velocity Transmitters are sold in this category which are ideal for monitoring air flow.

Flow

Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston.
