| Sierra Steel-Mass® Model 640S Inline, Totalizing Air Flow Meter for Industrial Application |
 |
Steel-Mass Model 640S can be customized for your air velocity and intake applications with:
- Larger probe lengths.
- High temperature option (750 degrees F).
- Self-cleaning purge option for dirty flow environments.
- Wide range of process connections (including hot tap).
- Multipoint flow averaging arrays for very large ducts, complete with a self-contained human-machine interface (HMI) panel for touch-screen field programming and system operation.
Steel-Mass inline air flow meters also feature Sierra's unique Smart Electronics Package for field rangeability, flow-range adjustment and validation and diagnostics. With very low pressure drops and wide turndowns, these products are hazardous-area approved by CSA and CRN (Canada); FM (USA); ATEX, CE and PED (EU); IEC Ex (Australia); GOST R (Russian Federation); and Chinese Pattern Approval (China). Meter accuracy is +/- 1% of reading, plus +/-0.5% of full scale with repeatability of +/- 0.2% of full scale.

Principle of operation
The flow network smart meter's operation is based on
an advanced calorimetric technology.
The sensor head of the flow network contains two PT-resistors.
One of them is measuring the temperature of the media,
while the other is heated by an attached heating resistor,
resulting in a temperature difference between the two
PT-resistors.
The temperature difference between the two PT-resistors
is predetermined and a control circuit keeps this temperature
difference constant.
The flow of the media cools the heated PT-resistor
proportional to the speed of the flow. The heating power
fed into the system by the control circuit, in order
to keep the temperature difference between the two PT-resistors
constant, is the equivalent to the heat dissipation
by the flow of the media. This results in a linear output
signal proportional to the flow speed. |

world's most advanced insertion flow measurement technology
available. Digital signal processing provides a measuring
system with unsurpassed accuracy, versatility and cost
of ownership. The system installs quickly into liquid
piping systems and can be configured and operational
within minutes. The exclusive insertion tip ensures
accurate and stable flow readings, even when poor system
hydraulics, flow swirl or very low flow rates are encountered.
The insert mag meter is designed for
permanent installation in full-pipe liquid systems.
The hot-tapped probe can be installed and retracted
from service without interrupting the process stream.
Other features include: bi-directional flow measurement,
continuous intelligent diagnostics, two-line backlit
alphanumeric display, tactile keypad, optically isolated
input/output busses and field replaceable input/output
communication modules.
These meters are direct replacements for insert Mag Probea,
insert mag meters or insert Venturi-notched tips. Reading
accuracy and reliability, especially at low flow rates,
are improved versus mechanical, DP and vortex shedding
flow meter performance. The insertion probe can be installed
and removed from service without turning off pumps or
draining piping - eliminating down time. User configurable
rate and totalizer units include: Feet, Gallons, FT3,
Mil-GAL, Barrels, Acre-Feet, Pounds, Meters, Liters, M3,
Mil-Liters and Kilograms.
