Applications:
MF5706 (0-20L/min) /MF5708 (0-100L/min) / MF5712 (0-250L/min) Gas mass flowmeters are suitable for different gases (such as air, compressed air, oxygen, nitrogen, CO² and other inert gases etc.) Instant flow test and flow accumulation calculation.

Features:
- Ultra-low power consumption via battery or optional external AC adapter
- Portable design, small size and easy installation - MEMS technology for small gas flow testing with high accuracy.
- RS485 Modbus protocol available for networking - User programmable range alarms for safety and other monitoring/control functions.

Product Features:
☆ The sensor chip adopts thermal mass flow measurement without temperature and pressure compensation, which ensures the high-precision measurement of the flowmeter.
☆ High sensitivity, can start to measure very small initial flow.
☆ Multi-sensor integration is realized on a single chip, making its turndown ratio reach 80:1 or even higher.
☆ Full-scale high stability, high accuracy and excellent repeatability.
☆ Supports the measurement of multiple gases, allowing customers to perform on-site calibration of some special gases quick response.
☆ 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.
☆ Parameters can be configured by key.
☆ With over-range alarm indication function.
☆ Portable design, battery power supply and external power supply mode can be switched arbitrarily
☆ G thread or NPT thread connection, easy to install and use, other interfaces can also be customized according to customer needs.
☆ Wide range of applications: mechanical and electrical industry. Food industry.Tobacco industry. Analytical instrument industry. Chemical industry. Beverage industry. Glass industry. Scientific research institutions. Pharmaceutical industry. Agriculture, forestry and fishery.
