Air / Oxygen Gas Mass Flow Meter (plus Kit) 5330-2

The TSI Mass Flow Multi-Meter 5330-2 provides a bi-directional flow rate measurement with an increased 1.7% of reading accuracy across a wide flow range. Integrated temperature and pressure sensors compensate flow measurements to provide mass flow readings independent of temperature or pressure. In addition to temperature and absolute pressure measurements, a built-in totalizer measurement enables users to make volume measurements as a running total. All 5300 Series inline flow meter models come with a standard accessory kit (see full list below). The 5330 model includes a tabletop stand.

Flow Multi-Meter advanced functionality

5330 mass flow meters consolidate many different devices into one instrument, includin: high accuracy flow meter, digital hygrometer, differential pressure sensor, volumetric flow meter, and more. The humidity sensor provides relative humidity readings and humidity compensated flow measurements. The added differential pressure sensor enables users to measure the pressure differential of flows at the flow meter or at any point in the line. In addition to the totalizer, these volumetric flow meter models can make precise volume measurements through the use of flow or pressure triggers. 5330 models also include a built-in data logger that can save synchronized measurement data directly to the flow meter.

Easy to operate

View up to four readings simultaneously from the color touchscreen display of this Air and O₂ flow meter. Quickly and easily configure measurements and device settings directly from the flow meter. Connect and operate the gas flow meter through your PC with FLO-Sight software to take advantage of advanced data display and device settings options.

Fits your application

TSI Flow Meters are lightweight, compact, and can measure across a wide dynamic operating range. The 5000 Series Flow Meter also incorporates configurable tube end adapters, touchscreen control, and multiple mounting options. Whether measuring gas flows in a laboratory, manufacturing, or service setting, the 5000 Series Flow Meter can adapt to fit your unique application.

Model 5330-2 high flow meter is ideal for CPAP testing (continuous positive airway pressure machine testing) in research and development (R&D) applications due to its ability to:

• Provide bi-directional flow sensing
• Measure differential pressure and flow rate simultaneously,
• Log data,
• Calculate humidity and provide the equivalent dry gas flow rate, and
• Provide higher accuracy readings

Proven performance

5000 Series Flow Meters utilize a proprietary platinum film sensor with proven performance that’s been relied upon for more than 35 years. The TSI mass flow sensor design is optimized for applications where high accuracy, fast response, and low pressure drop are performance musts. Fast sensor response ensures accuracy in fluctuating flows and is ideal for closed-loop control systems and integrated volume measurements. The low pressure drop of TSI flow meters minimizes flow circuit back pressure and its impact on the system.

Includes our Standard Accessory Kit:

• low pressure inlet filter
• AC adaptor with universal plug set
• USB-C to USB-A power/communications cable
• USB hub cable
• 1/2 inch tube ends

*All 5300 Series flow meters come with 22mm end adaters and end caps attached.*
