ST Thermal Mass Flowmeter Manufacturers

The ST series thermal mass flow meter is specifically designed for gas measurement, capable of directly measuring gas mass flow and temperature without requiring additional pressure or temperature compensation. It features an advanced all-stainless steel construction with no moving parts, ensuring high reliability and minimal maintenance needs. The product offers negligible pressure loss and is suitable for various industrial pipeline systems, providing precise and stable flow monitoring solutions.

• Direct Measurement: No need for pressure or temperature compensation; directly outputs gas mass flow and temperature values.

• Low Pressure Loss: Negligible pressure drop, ideal for applications sensitive to system pressure.

• High Accuracy and Wide Turndown: High measurement precision with a turndown ratio up to 100:1, accommodating a broad flow range.

• Fast Response: High sensitivity with response time less than 0.5 seconds, providing reliable zero-point stability.

• Robust Design: Full stainless steel structure with no moving parts; wear-resistant, corrosion-resistant, requiring no mechanical maintenance and offering high reliability.

• Flexible Installation: Supports flange, threaded, or insertion-type installation; can be mounted horizontally or vertically. Insertion type is suitable for round or rectangular ducts and comes with a ball valve accessory for quick, safe removal without interrupting flow.

• Intelligent Display: Modular and intelligent indicator design with flexible integrated or split display options; on-site LCD screen displays instantaneous flow, cumulative flow, velocity, and temperature in real time.

• Self-Diagnosis Function: Built-in self-diagnostics to check the operating status of the probe, electronic circuits, and other components.
