Dwyer Flow Meters

Industrial flow measurement and testing instruments including a portable airflow measurement kit, variable area flow meters (rotameters), and a digital mass flow transmitter used for monitoring gas and air flow in HVAC and process systems.

Dwyer flow meters are available for measuring liquid, gas, and air flow in industrial, commercial, HVAC, and process control applications, with mechanical and electronic models suited for a wide range of flow rates and system requirements.

Dwyer is a well-known brand for versatility and accuracy in flow measurement. While many meter manufacturers focus on electronic solutions, Dwyer has maintained a strong portfolio of mechanical flow meters with simple, low-maintenance designs. Many models are easy to read, feature good visual contrast, and support low enough flow rates to be applicable not just to large systems but also to small pathways like ductwork. Their variable area meters are a customer favorite for straightforward visual flow monitoring in laboratory settings, industrial skids, and HVAC systems alike.

Dwyer flow meters are built for real-world performance. Most models are constructed with durable materials, including polycarbonate, stainless steel, and corrosion-resistant plastics designed to withstand demanding conditions. Whether operating under pressure, in high-temperature environments, or with fluid media that changes viscosity, Dwyer flow meters maintain consistent performance without sacrificing accuracy or reliability.
