Product Descriptions

The AMS1000 gas mass flow meter series is based on the principle of thermal measurement, which calculates the mass flow rate of the 

measured gas by measuring resistance changes. The product adopts a self-developed MEMS flow sensor chip, which is an excellent, stable and 

reliable gas mass flow meter with characteristics such as precision, stability, high and low temperature resistance, good linearity, and fast 

response; The internal alarm function is equipped with an LCD display screen for reading display, making the detection status clear at a glance; 

It has multiple output modes such as RS485, NPN collector open circuit, 1-5V linear voltage, and 4-20mA linear current, which can meet the 

personalized needs of different customers. This series has multiple models, covering multiple range ranges, and is suitable for a wide range of 

scenarios.

Product Features

•  Integrated mass flow and temperature measurement

•  Good repeatability

•  Supports multiple gas measurements

•  Standard Modbus RTU communication

•  2 NPN collector open circuit outputs (for upper and lower limit alarms)

•  Multi range, from 0-2L/min to 0-500L/min

•  LCD screen display (can support four display directions: up, down, left, right)

Product Applications

The AMS1000 series can be applied to monitor the mass flow rate of dry, clean, and non corrosive gases (excluding flammable and explosive 

gases) such as air, nitrogen, argon, carbon dioxide, and oxygen. It can be widely applied in industries such as scientific research in universities, 

fire protection, environmental monitoring, tobacco, smart agriculture, food, medicine, etc.
