Properties
Application
The corrosion resistant compact variable-area flowmeters series FMare used for continuous extractive gas analytics. They are usually integrated downstream the sample gas cooler and serve e.g. for adjustment of the sample gas flow rate for analyzer and bypass within a gas analysis system.
Technology
The highly corrosion resistant compact variable-area flowmeters series FMwith their measuring tube made of borosilicate glass are equipped with a precise and very robust stainless-steel needle valve. Due to the special design the valve has an almost linear control characteristic. The flowmeters can be equipped with a sensor light barrier which transmits a signal in case of missing flow via connected optional electronic control EC72.01. Due to the G1/8” f-thread the sample gas connections can be determined variably by means of an appropriate screw fitting.
Functions
The flow is clearly visible in the measuring glass of the flowmeter and the current flow rate can be read easily from the scale directly at the top of the float. The linear control characteristic of the fine adjustment valve enables monitoring and dosing of extremely low flow quantities.
