battery powered gas air flow meter sensor with LED display

Product Application

The fluid and its given and its pressure, temperature, allowable pressure drop, density (or specific gravity), conductivity, viscosity (Newtonian or not?) and vapor pressure at maximum operating temperature are listed, together with an indication of how these properties might vary or interact. In addition, all safety or toxicity information should be provided, together with detailed data on the fluid's composition, presence of bubbles, solids (abrasive or soft, size of particles, fibers), tendency to coat, and light transmission qualities (opaque, translucent or transparent).

Main Features

Dedicated instrument for gas measurement

1. Cast stainless steel housing that could ensure high strength and good corrosive performance.
2. Product integrated micro processor, temperature sensor and pressure sensor for direct measurement of flow rate, temperature and pressure of the medium. It could also conduct temperature and pressure compensation for flow rate and amend compression factors automatically.

3. Adopt the latest fourth generation Tunneling Magnetoresistive (TMR) sensor, which could greatly improve the anti-electromagnetic interference performance.
4. Low consumption design, product could use external power or with lithium battery that could be used successively for more than four years. And 3.6v lithium battery with 2 years service life, it is one-off, can not charge.
