It supports preset multi-gas switching, wide-voltage analog signal input/output and fast response regulation, suited for precise proportioning and constant flow delivery of conventional high-purity inert gases and process gases. Featuring compact structure, strong anti-interference capability and zero drift during long-term operation, it is widely deployed in new precision gas system construction, replacement of aging flow controllers and technical upgrading of process equipment. It serves as a mainstream core device for precise gas control at low and medium flow rates.
2. Technical Features
2.1 High Accuracy & Repeatability for Excellent Process Adaptability
The unit achieves premium measurement accuracy of ±1.5% RD within 10%~100% full scale, zero drift down to ±0.5% FS, and typical repeatability of ±0.2% RD, ensuring stable and controllable error across the full flow range. It precisely satisfies high-precision process requirements for semiconductor deposition, thin-film coating, precision gas proportioning and carrier gas regulation for instruments. It effectively guarantees process consistency and product yield, avoiding process deviations induced by flow fluctuations.
2.2 Native Thermal Measurement, No Operating Condition Compensation Required
Built upon mature capillary bypass thermal sensing technology, it directly acquires gas mass flow data. Unlike conventional volumetric flow equipment, readings are unaffected by supply pressure and ambient temperature variations. Embedded global automatic temperature compensation algorithms sustain accurate and stable flow control under complex conditions without secondary manual calibration, suitable for continuous precision production processes.
2.3 Intelligent Multi-Gas Switching with Broad Versatility
Calibrated for Nitrogen (N₂) by factory default, it stores coefficients for 10 commonly used process gases. Gas type can be rapidly switched via DIP switches on the unit, supporting regular high-purity gases such as N₂, O₂, Ar, He, CO₂ and compressed air. No factory recalibration is required, allowing a single unit to accommodate multi-gas process scenarios and substantially reduce equipment procurement and maintenance costs.
2.4 All-Metal Sealing for High Cleanliness & Leak Prevention
The primary flow path is constructed from 316L stainless steel, supplied with Viton fluorocarbon elastomer seals as standard; Kalrez premium sealing is available as an option. The overall design meets high-cleanliness process requirements for semiconductor and photovoltaic industries. The fully sealed structure conforms to SEMI F72 leak-tight specifications with zero gas leakage and no impurity precipitation, preventing process failures caused by gas circuit contamination and micro-leakage and adapting to high-purity precision gas environments.
2.5 Ultra-Fast Response & Stable Flow Control with Superior Dynamic Performance
Response time ≤1.5 s (0~90% setpoint). The unit rapidly follows flow setpoint changes issued by the system and accurately modulates valve opening to stabilize flow quickly. Under dynamic conditions including process startup/shutdown, minor load trimming and multi-gas proportioning, it operates without lag, overshoot or fluctuation, perfectly matching high-precision dynamic flow control applications.
2.6 Comprehensive Electrical Protection for Long-Term Industrial Operation
It accepts wide-range 24 V DC power supply, integrated with reverse power protection, over-limit flow alarm and signal anti-interference design. Excellent insulation enables tolerance to electromagnetic interference and minor voltage fluctuations on site. Low power consumption generates low temperature rise; free of vulnerable moving components, it features an extended maintenance-free cycle and supports 7×24-hour unattended continuous operation for industrial automation and long-term laboratory applications.

4. Operating Principle
The BROOKS 001-4130-03 operates based on the thermal conduction mass flow measurement principle, adopting a mainstream capillary bypass flow splitting structure with stable closed-loop workflow. After gas enters the unit, the flow is divided into a main stream and a sensing bypass. Gas flowing through the bypass uniformly passes over temperature sensing and heating elements. By precisely detecting the temperature difference induced by heat carried away by the gas, combined with embedded high-precision algorithms and temperature compensation models, the true gas mass flow rate is calculated directly without secondary conversion for pressure and temperature.
During operation, the unit continuously compares the actual flow rate against the setpoint transmitted from PLC/control systems, automatically adjusting the opening of the built-in precision solenoid valve via closed-loop control to dynamically correct flow deviation and maintain constant flow. Meanwhile, analog feedback signals are output in real time to transmit flow data to upper-level systems. Together with over-limit alarm functions, it realizes full closed-loop management covering precise gas flow measurement, automatic regulation, real-time monitoring and abnormality early warning, ensuring sustained stable flow and accurate gas proportioning in process gas circuits.
