Application

The compact, flat, corrosion resistant FM 40
flowmeter for front panel mounting is used
for flow control of gas media in analysis
devices and systems.

Description

The M&C FM 40 flowmeter consists of a verti­cal, internally conical glass tube widening
towards the top in which a float can move
freely upwards and downwards and of the
head and bottom piece with an integrated
PVDF needle valve. A “front panel“ of a maxi­mum 4 mm thickness with two appropriate
mounting bore holes serves as base body for
attaching the head and the bottom part.

The sample gas flows upwards through the
tube and thus lifts the float until a radial clear­ance occurs between the tube wall and the
float so that forces effecting the body are in
equilibrium. Thus every position of the float
(depending on measuring range out of glass
or Hastelloy C) corresponds to a certain flow
which can be read on a calibrated scale.

The measuring tube is sealed within the head
and bottompart with FPM o-rings, as is the
fine adjustment needle valve.

All parts coming into contact with the gas
medium are made of PVDF, FPM and glass.
The flowmeter is fitted with a fine adjustment
valve in the inlet for precise flow value setting.
In addition, the optical monitoring unit FA1bi
is supplied for automatic flow alarm monitor­ing. – See separate data sheets 9.4 / 9.5 –
