Description MF5700 series Air oxygen gas flowmeter Micro gas mass
flowmeter
The MF5700 mass flow meter is one of the best selling mass flow
meter products on market, due to its performance and cost effective
design enabled with the company’s proprietary MEMS (micro electro
mechanical systems) thermal sensing technology. The current model
is the 3rd generation of the products having significantly upgraded
features since its first release in 2010. The upgrade includes much
improved accuracy, an additional model to cover flow range and
channel size compatibility; significantly extended measurement
dynamic range, wireless data options, and valve options. The
upgrade also ensures back compatibility for our existing customers.
Siargo is committed to continuing product innovation while offering
the best value to our customers.
This serial of products is designed for general purpose mass flow
sensing and control purposes. The wetted materials of the products
are compatible with most of the common gases such as oxygen,
nitrogen, air, argon, carbon dioxide, etc. Siargo also offers a
wide spectrum of off the shelf and customized flow, pressure,
temperature/humidity, and gas concentration sensing products and
provides integration and turn key solutions to our customers.
