Summary
AMS3 series gas mass flowmeter is based on the principle of thermal measurement, combined with the self-
developed MEMS flow sensor chip, to create an excellent performance, stable and reliable gas mass
flowmeter. The product calculates the mass flow rate of the measured gas by measuring the change of
resistance. It has the advantages of accuracy, stability, high and low temperature resistance, good linearity
and fast response. The alarm function is set inside the product, equipped with TFT display for reading display,
and the detection status is clear briefly; With RS485, NPN collector open circuit, 1 ~ 5V linear voltage and 4 ~
20mA linear current and other output modes, can meet the individual needs of different users.
The series has a variety of models, covering a variety of ranges, suitable for a wide range of scenarios.
Application
AMS3 series is suitable for mass flow monitoring of dry, clean, non-corrosive gases such as air and nitrogen
(except flammable and explosive gases). It has been widely used in university scientific research, fire
protection, environmental monitoring, tobacco, smart agriculture, food, medicine and other industries.

Piping diagram (1) For the air pipe connected to the air inlet port of the AMS3 series products, please reserve a straight pipe section that is greater than or equal to 10 times the inner diameter of the air inlet port, and the inner diameter of the straight pipe must be greater than or equal to the inner diameter of the air inlet port.
- Page 8 The communication protocol is standard Modbus RTU. The host can be a computer, RS485 receiver, MCU controller, etc. The AMS3 series is a slave, the default address is 0x01, supports address modification, and can be connected to the bus of multiple slaves.
- Page 9 AMS3 Series Gas Mass Flowmeter Take the operation of AMS3006H00 as an example, as follows. The host reads the instantaneous flow value of AMS3006H00 (the default slave address of the device is 0x01), the host sends a command to AMS300 6H00, and the data is 01 03 00 00 00 01 84 0A. The format is shown in Table 7.
