Product Introduction

I. US Siargo MF5700 Series PortableGas Mass Flow MeterProduct Overview:

The MF5700 series gas mass flow meter is based on the MEMS flow sensing chip independently developed by Siargo Micro Electro Mechanical Systems Co., Ltd. Its principle utilizes the interdependent relationship between heat transfer and mass transfer of flowing gas, generating temperature changes upstream and downstream to obtain the gas mass flow rate.

The flow meter simultaneously generates the heat source and measures temperature. When the chip is in operation, a stable temperature field distribution forms around the sensor. Once a certain mass of gas flows through the sensor, the gas flow disrupts the temperature field distribution, creating a specific temperature field distribution that depends on the mass and velocity of the gas. The sensor on the MEMS flow meter chip measures this change and converts it into an electrical signal, which is amplified, conditioned, and linearized by a dedicated transmitter circuit. Since different masses of gas cause different disturbances to the stable temperature field around the sensor, the mass flow rate or total flow of the gas can be measured. The figure below shows the principle block diagram of this series of flow meters.
