Dwyer Flow Meters

The Dwyer flow meter is a well-known brand in terms of versatility and accuracy for measuring the flow of liquids and gases in industrial, commercial, and HVAC applications. While many meter manufacturers focus on electronic solutions, Dwyer Technology has maintained a strong portfolio of mechanical flow meters that are simple and have a low-maintenance design. Many models are easy to read, feature good visual contrast, and have low enough flow rates that they are applicable not just to large systems but also suitable for small pathways like ductwork. Their variable area meters, in particular, are customer favorites for eyeing the flow with a simple peek either in a laboratory setting or in a large industrial skid or HVAC system.

Dwyer flow meters are designed to function in the real world. Most models are built with durable materials like polycarbonate, stainless steel, and corrosion-resistant plastics. They’re designed to withstand demanding conditions. Whether under pressure, in a high-temperature environment, or in fluid medium that changes viscosity when heated, these meters keep on keeping on without losing their edge in performance.
