Thermal Mass
Flowmeters - The rate of heat absorbed by a
flow stream is directly proportional to its mass
flow. As molecules of a moving gas come into contact
with a heat source, they absorb heat and thereby
cool the source. At increased flow rates, more molecules
come into contact with the heat source, absorbing
even more heat. The amount of heat dissipated from
the heat source in this manner is proportional to
the number of molecules of a particular gas (its
mass), the thermal characteristics of the gas, and
its flow characteristics. |

We designed our Heavy-Industrial Thermal mass
flow meter products for the most demanding industrial
gas mass flow measurement applications. Featuring
heavy-duty 316 stainless steel wetted materials,
no moving parts and digital signal processing,
our Heavy-Industrial Thermal line is the answer
for the roughest industrial environments. Our
Model 640S Steel-Trak™ is an insertion probe
design and our Model 780S Flat-Trak™ is an
inline design featuring an integrated dual-plate
flow conditioning element (Flow=Trak™) that
allows the instrument to maintain top performance
in heavily constrained piping environments where
long-straight pipe runs simply do not exist. Our
Model 780S-UHP is an inline flow conditioned design
for gas distribution in ultra clean processes.
All models feature DIRECT mass flow measurement
and Sierra’s Smart Electronics Package for
field-rangability, flow-range adjustment, and
meter validation and diagnostics.

The Model 780S Flat-Trak™
offers improved measurement capabilities in installations
where long straight pipe runs are not available. The
meter incorporates Sierra’s unique dual-plate flow
conditioning element to eliminate velocity profile distortions
as well as swirl and temperature stratification in the
gas stream. This product reduces piping straight run
requirements to as little as three upstream diameters.
As a result, you save money on installation costs when
compared to an orifice-plate where at least 20 upstream
piping diameters are required for optimal performance.
The Model 780S is available in pipe sizes from 1/4-inch
to 8-inches in a choice of NPT, Buttweld or ANSI 150
lb. flanged design (300 lb. flanges optional). Larger
sizes are available upon request. This meter features
Sierra's well-known Smart Electronics Package for field-rangability,
field flow-range adjustment, and field validation and
diagnostics. The Model 780S has outstanding low-velocity
sensitivity and exceptional accuracy.
The Model 780S is hazardous area approved for FM, CSA,
EEx, PED, CE, CENELEC and is also available with a NEMA
4X (IP65) enclosure. Product accuracy is ±2% of reading,
0.2% of full scale repeatability. More>> |
