Variable area flowmeter or
high-precision mass flow meter:
The user determines the
device |
Variable area flowmeters for plant
and apparatus construction are just as popular as ever. The numerous
advantages in daily practice are convincing: cost-effective purchase,
simple installation and handling, maintenance-free and independent
operation.
Certain applications require measurement accuracy, with
respect to pressure and temperature independence, which cannot
be achieved with conventional variable area flowmeters. This is
where the 'red-y compact' thermal mass flow meters
come into their own. Alongside the advantages of the variable area
flowmeters, the devices offer extremely precise and rapid measurement
with digital
CMOS sensors and run independent of mains electricity thanks to
battery power. |
