This all-in-one flow meter simplifies your work by eliminating the need for multiple instruments and is flexible enough to fit your unique application.

All TSI flow meters integrate flow, absolute pressure, and temperature sensors to deliver readings and compensate flow measurements. 5000 Series base models also incorporate bidirectional flow sensing, color touchscreen display, configurable tube end adapters and companion PC software.
Advanced models can integrate flow rate, absolute pressure, temperature, volume, differential pressure, and humidity measurements into a single, compact device. Additional models include options for higher flow accuracy, data logging, humidity compensation, or a wide flow accuracy specification.

High and Low Flow Options
The 5300 Series is TSI’s high flow thermal mass flow meter and can measure up to 300 Std L/min while maintaining a low pressure drop.
The 5200 Series is TSI’s low flow option, that measure up to 30 Std L/min and provide increased resolution at flow rates under 1 Std L/min.
