Product Overview
The AMS1000 Gas Mass Flow Meter series utilizes a thermal measurement principle to accurately measure gas mass flow by detecting resistance changes. Engineered with a proprietary MEMS flow sensor chip, it delivers exceptional performance, stability, and reliability. Key features include high precision, stable readings, resistance to high and low temperatures, excellent linearity, and fast response times. The device integrates an alarm function and an LCD display for clear status indication. It offers versatile output options, including RS485, NPN open collector, 1-5V linear voltage, and 4-20mA linear current, catering to diverse customer needs. Available in multiple models with various ranges, the AMS1000 is suitable for monitoring dry, clean, non-corrosive gases such as air, nitrogen, argon, carbon dioxide, and oxygen (excluding flammable or explosive gases). It finds broad application in university research, fire safety, environmental monitoring, tobacco, smart agriculture, food, and pharmaceutical industries. Each unit undergoes rigorous testing and calibration before shipment to ensure high-quality delivery.
