Basic and Advanced Models

All TSI gas mass flow meters integrate flow, absolute pressure, and temperature sensors to deliver readings and compensate flow measurements. All of our 5000 Series models also incorporate bidirectional flow sensing, color touchscreen display, and configurable tube end adapters. 

Advanced 5000 Series Flow Meter models can simultaneously measure flow rate, absolute pressure, temperature, volume, differential pressure, and humidity in a single, compact device. Additional models include options for higher flow accuracy, data logging, humidity compensation, or a wide flow accuracy specification. See the Model Guide below to find a model that will work best for your application and download the FLO-Sight software.

High Flow and Low Flow Options

The 5300 Series is TSI’s high flow thermal mass flow meter. The 5300 Series can measure up to 300 Std L/min while maintaining a low pressure drop.  These flow meters are lightweight and compact, especially when compared to other instruments that measure similar flow rates.

The 5200 Series is TSI’s low flow thermal mass flow meter. These flow meters can measure up to 30 Std L/min and provide increased resolution at flow rates under 1 Std L/min. The 5200 Series flow meters are designed with reduced internal volume to minimize circuit dead space and deliver highly accurate volume measurements.
