Digital Gas Flow Meter Portable Gas Mass Air Nitrogen Oxygen Flow Rate Meter

Note: Battery not Included During The Shipping !!!



Introduction:
  • MF5700 series mass flow meters are designed for general purpose flow metering and control applications enabled. With proprietary MEMS mass flow sensing technology and smart electronic circuitry, the products offer unprecedented cost-effectiveness with performance. 
  • The sensors directly measure mass flow with a very low pressure loss, opt with various wireless transmissions, and control ON/OFF valve. The current models can be readily applied to many process applications.

Features:

  • Battery powered, portable design.
  • RS485 communication can be centralized management of the network (optional)
  • Real-time monitoring of instantaneous flow and calculation of accumulated traffic
  • Password management, overrun alarm
  • Small size, easy to install. 

Application:

  • Applied to all kinds of gas flow testing and flow metering, suitable for air compressed air oxygen nitrogen dioxide and all kinds of inert gas, such as the instantaneous flow and cumulative flow measurement
  • Food industry mechanical and electrical industry tobacco industry analysis instrument in chemical industry and beverage glass industry scientific research colleges and universities of the pharmaceutical industry Agriculture, forestry and fisheries, and other fields
