Air / Oxygen Gas Mass Flow Meter (plus Kit) 5303-2

Product Details

The TSI Mass Flow Multi-Meter 5303-2 provides a bi-directional flow rate measurement with 3% 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).

Pass more as-found calibration checks

Model 5303 Flow Meters come with an accuracy specification of 3% reading or 0.1 Std L/min. This wider specification reduces the chance of the flow meter failing its annual ‘As-Found’ calibration check. If a flow meter is found to be out of tolerance during a calibration check, it may require an internal risk analysis or other action as part of a company’s quality management system. Reducing the number of failed calibration checks will help reduce these costly implications. It is important to note that the model 5303 is calibrated to the same accuracy as TSI’s other 2% flow meters, only its published accuracy specification has been widened.

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.

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.*
