MF5700 Series Gas Flow Meters
Executive standard: Q/SI 00013-2020.
Reference standard: ISO14511; GB/T 20727-2006.
Features
1: The sensor chip adopts thermal mass flow measurement without temperature and pressure compensation, which ensures the high-precision measurement of the flowmeter
2: High sensitivity, can start to measure very small initial flow
3: Multi-sensor integration is achieved on a single chip, enabling its turndown ratio to reach 80:1 or even higher
4: Full-scale high stability, high accuracy and excellent repeatability
5: Supports the measurement of multiple gases, allowing customers to perform on-site calibration of some special gases
6: Fast response time
7: The output mode is flexible, providing LCD on-site display, and can also provide RS485 communication interface to query the output data from the host computer
8: Parameters can be configured by keys
9: With over-range alarm indication function
10: Portable design, battery power supply and external power supply mode can be switched arbitrarily
11: G thread or NPT thread connection, easy to install and use, other interfaces can also be customized according to customer needs
Working Principle
The flow meter simultaneously realizes the generation of heat source and the measurement of temperature. When the chip is in working state, in the sensor
A stable temperature field distribution is formed around it. Once a certain mass of gas flows through the sensor, the flow of gas will destroy the
The distribution of the temperature field, resulting in a specific temperature field distribution that depends on the mass and velocity of the gas. MEMS flow
The sensor on the gauge chip will measure this change and convert this change into an electrical signal, which is converted by a special circuit.
The transmitter amplifies, conditions and linearizes the signal. Due to the different mass of gas on the peripheral shape of the sensor
The disturbance generated by the stable temperature field distribution is different, so the mass flow or total flow of the gas can be measured. The picture below is
