Hose Flow Tester: Precision Measurement for Gas Hose Flow Capacity
The Hose Flow Tester is a specialized instrument engineered to evaluate the flow capacity of stainless steel corrugated hoses used in gas appliance connections. Its testing principle is rooted in simulating real-world gas flow conditions: 2kPa of air is introduced at the hose inlet, and a control valve adjusts the flow to maintain a standard pressure differential across the hose. The flow rate measured under this controlled condition directly reflects the hose’s ability to transmit gas efficiently—critical data for ensuring safe and reliable performance in residential, commercial, and industrial gas systems.
This tester strictly complies with GB/T 41317-2022, the Chinese national standard governing the performance testing of stainless steel corrugated hoses for gas appliances. Adherence to this standard guarantees that flow rate measurements align with industry safety and efficiency benchmarks, making the machine an essential tool for manufacturers, quality control teams, and regulatory bodies focused on gas system integrity.
Premium Engineering
Crafted with exquisite machining precision and a unique industrial design, the tester balances durability with user-centric functionality. Its robust frame and high-grade materials ensure stability during extended testing sessions, while ergonomic features—such as easy hose connection ports, clear gauge displays, and accessible maintenance panels—simplify operation. The compact footprint (1784×520×767mm) maximizes lab space efficiency, making it suitable for both production floors and testing laboratories.
Intelligent Control System
Equipped with a PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) large-color LCD touchscreen, the tester offers intuitive, automated control. Operators can input hose specifications, set test parameters, and monitor real-time data (flow rate, pressure differential, temperature) via the user-friendly interface. This digital integration eliminates manual calculations, reduces human error, and streamlines workflows—critical for high-volume testing environments.
Precision Measurement Technology
- High-Precision Mass Flow Meter: A state-of-the-art mass flow meter (0–20m³/h range, 0.01m³/h accuracy) delivers precise flow rate detection, with a base-state conversion display that adjusts readings to standard conditions for consistency. This level of accuracy ensures even minor flow restrictions in hoses are detected, preventing potential gas supply issues.
- Real-Time Temperature Monitoring: A PT100 temperature sensor tracks ambient temperature throughout testing, accounting for thermal effects on air density—critical for accurate flow rate calculations, as gas volume varies with temperature.
- Dual Digital Micro-Pressure Gauges: High-precision digital gauges measure inlet and outlet pressures with exceptional accuracy (0–5kPa range, 0.001kPa resolution). This dual monitoring ensures the pressure differential is maintained exactly as specified in GB/T 41317-2022, eliminating variability that could skew results.
Automated Data Processing
The tester’s integrated software automatically calculates the target pressure differential based on input specimen specifications (e.g., hose length, diameter). This automation reduces reliance on manual calculations, minimizing errors and accelerating the testing process. Test results—including flow rate, pressure differential, and temperature—are displayed in real time on the HMI touchscreen and can be stored or exported for documentation, simplifying compliance reporting.
These parameters highlight the tester’s focus on precision: the mass flow meter’s 0.01m³/h accuracy ensures compliance with the strict tolerances of GB/T 41317-2022, while the pressure sensor’s 0.001kPa resolution guarantees stable pressure differential control. The PT100 temperature sensor adds another layer of data integrity, ensuring flow rates are adjusted for environmental conditions.
The Hose Flow Tester is specifically designed for evaluating stainless steel corrugated hoses used in:
- Residential Gas Appliances: Stoves, water heaters, and boilers, where consistent gas flow is critical for efficiency and safety.
- Commercial Kitchens: Heavy-duty gas equipment, where restricted flow can disrupt operations or pose hazards.
- Industrial Gas Systems: Manufacturing facilities, where precise gas delivery impacts process stability and worker safety.
By simulating real-world pressure conditions, the tester helps identify flow restrictions caused by manufacturing defects, kinks, or material degradation—issues that could lead to inadequate gas supply or dangerous pressure buildup. For manufacturers, it ensures compliance with GB/T 41317-2022; for regulators, it provides a standardized method to verify product performance.
The Hose Flow Tester combines advanced measurement technology, intelligent automation, and adherence to global standards to deliver accurate, reliable flow rate data for gas hoses. Its precision sensors, user-friendly interface, and automated data processing make it an indispensable tool for ensuring the safety, efficiency, and compliance of stainless steel corrugated hoses in gas systems. Whether used in production quality control or regulatory testing, this machine empowers stakeholders to uphold the highest standards of gas appliance performance.
