TSI 5300 Series High Flow Thermal Mass Flow Meter,Air O2 CO2 N2 Gas Flow Sensor.PDF
The TSI 5300 Series thermal mass flow meter is engineered for high-flow gas measurement with ultra-low pressure loss. It can reach a maximum flow rate of 300 Std L/min, effectively reducing flow backpressure and disturbance to the original gas pipeline system.
Compared with other flow sensors with equivalent flow range, this product features lighter weight and more compact overall size. Positioned as a universal medical flow meter, the 5300 series is highly optimized for respiratory medical industry scenarios, perfectly matching ventilator, anesthesia machine, CPAP/BiPAP and other respiratory device testing, development and quality control work.
3.Full Bidirectional Flow Detection
Supports forward and reverse gas flow measurement; separate accuracy parameters for inflow/outflow to meet inspiratory & expiratory bidirectional testing of breathing equipment.
Volume unit: L, mL, ft³
0.5 inch unfiltered pipeline
22mm (0.75 inches) unfiltered pipeline
22mm (0.75 inches) with built-in filter
0.5 inch with built-in filter
The filter-equipped model can intercept gas impurities and protect the internal sensing elements; the overall pressure drop is lower for larger pipe diameters.
Installation hole spacing: 70mm (2.76 inches)
Installation hole width: 21mm (0.83 inches)
Total equipment height: 50.9mm (2.00 inches)
Machine depth: 69.9mm (2.75 inches)
Installation thread specification: M3

Core Advantages
1.Multi-gas Compatible Calibration
User-selectable calibrated gases: Air, Oxygen (O₂), Carbon Dioxide (CO₂), Nitrogen (N₂); nitrogen measurement is converted and corrected based on air calibration data.2.Ultra-Low Pressure Drop Design
Multiple pipeline aperture options: 0.5 inch / 22mm (0.75 inch); optional built-in filter version. Pressure loss curve is clear, greatly avoids pipeline pressure fluctuation during respiratory equipment testing.3.Full Bidirectional Flow Detection
Supports forward and reverse gas flow measurement; separate accuracy parameters for inflow/outflow to meet inspiratory & expiratory bidirectional testing of breathing equipment.
4.Multiple Precision Models for Selection
5 sub-models with graded accuracy (1.7%~3% FS), meet high-precision lab research and cost-controlled mass production inspection respectively.5.Ultra-Fast Response Speed
4 ms response time to reach 63% of full scale, captures instantaneous breathing flow changes of ventilators without signal lag.6.Flow + Cumulative Volume Dual Measurement
Real-time flow value + total gas volume cumulative statistics (0.004~99L volume range), supports quantitative gas delivery verification.7.Rich Unit Options
Flow unit: L/min, ft³/min (Standard/Volumetric/Actual/Remote)Volume unit: L, mL, ft³
8.Compact Medical-grade Structure
Integrated small housing, M3 mounting thread, fixed installation hole positioning; precise dimension parameters convenient for fixture integration on production lines and test benches.| Item | Specification |
