Digital Gas Mass Flow Meter Oxygen, Nitrogen Air Flow Tester

Product Overview

MF5700 series flow meters measure flow mass flow sensor that is installed in the flow cannel forming a plate that serves as an additional flow conditioner from the boundary layer configuration resulting in a laminar flow. The mass flow measurement is established as the temperature field. Accurate flow rate is obtained by calibration with the standard fluid at the preset conditions.

Product Features

1.Two power supply modes:
①. Power adapter: External power (5-24) VDC
②. Four AA batteries (LR6), 6VDC
2. The sensor chip adopts thermal mass flow measurement without temperature and pressure compensation, which ensures the high-precision measurement of the flowmeter.
3. High sensitivity, can start to measure very small starting flow.
4. Multi-sensor integration is realized on a single chip, so that its range ratio reaches 80:1 or even higher.
5. High stability, high accuracy and excellent repeatability throughout the process.
6. Support a variety of gas measurement, fast response speed.
7.Parameters can be configured by pressing the button, and it has the function of over-range alarm indication.

Cautions
