Why Choose the TRX Ultrasonic Air Flow Meter?
Whether looking to reduce compressed air costs, monitor compressor efficiency, or implement predictive maintenance, the TRX Series provides unmatched performance, reliability, and cost-efficiency—all without system interruptions or pressure loss.
- No Pressure Loss
Designed with a clear flow path and no moving parts, the TRX ensures zero pressure drop and zero energy loss, improving system efficiency. - Long-Term Accuracy & Maintenance-Free Operation
The TRX provides high-accuracy air flow measurement without degradation over time—no recalibration, no filter replacements, and no scheduled maintenance for up to 10 years. - Exceptional Durability in Harsh Environments
With a robust build resistant to oil mist, moisture, and dust, the TRX performs reliably in contaminated or unfiltered compressed air lines. - Leak Detection & Low Flow Sensitivity
Thanks to its wide turndown ratio (1:60), the TRX precisely detects low flow rates and air leaks, enabling proactive maintenance and energy savings.
- Reverse Flow Measurement
Capable of monitoring bi-directional flow, it's perfect for loop piping systems and inter-factory air distribution. - Multiple Gas Compatibility
Suitable for air, nitrogen, and inert gases, with multiple output options including RS485 Modbus, analog (4-20 mA), pulse, and alarm signals. - Energy Optimization Ready
When paired with a watt-hour meter, the TRX helps calculate the air/power ratio (kW/m³), offering real-time insight into compressor efficiency and operational cost.
