2 Overview of the blowing unit
MTFC10 series purge device adopts variable area flow meter and constant flow valve to form a
purge device, which realizes flow measurement and stable output in occasions of pressure
fluctuation. The device adopts all-metal structure, with the characteristics of small volume, small
pressure loss and large range ratio (10:1). It can be used in various industries in complex and harsh
environments, as well as the flow measurement and process control of micro flow, low flow rate,
and various harsh medium conditions. It is especially suitable for measuring turbid, opaque or
corrosive fluids, or flow measurement with vibration occasions. According to different user needs
and different occasions, there are a variety of measurement forms for users to choose from.
According to the output form, there are local indication type and remote transmission type.
According to the constant-flow valve form, there are inlet constant flow valve type, export constant
flow valve type.
