T E C H N O L O G Y
Thermatel flow transmitter Model TA1 measures mass
flow by detecting heat dissipation from a heated surface.
The sensor contains two mass balanced elements with
precision matched RTDs. The reference RTD measures
the process temperature; the active RTD measures the
temperature of the heated element. The temperature
difference between the two RTDs is greatest at low flow
and decreases in a non-linear relationship as the flow
increases. The instrument accurately measures this temperature differential and converts it to a linear flow signal

B O D Y
with a 100-to-1 turndown.
The microprocessor-based electronics provide the ability
to configure the instrument for your exact process
conditions, provide advanced diagnostics, plus advanced
temperature compensation program to ensure accurate,
repeatable flow measurement over the entire operating
range of the instrument.
The TA1 is available with either an insertion probe or
flow body.

INSTALLATION
Probes can be provided with a variety of process
connections, including threads, flanges, or installation
through a compression fitting. The sensor will fit pipe
sizes of 11⁄2" diameter or larger (2" minimum with thread
connection).
The sensor is protected to prevent damage due to
“bottoming-out” if inserted too far into a pipe.
When using an insertion probe with compression fitting,
the user can adjust the position of the sensor in the pipe
to obtain the optimum location. Typically, this will be
with the bottom of the probe 1.0" lower than the center
line of the pipe.
TOTALIZER
The software totalizer provides an eight-digit display of
the most significant numbers in the user’s choice of engineering units. If the totalized display exceeds eight digits,
then the display changes to exponential notation. The
use of EEPROM for storage of totalized data eliminates
the need for backup batteries and provides maximum
safeguard of data in the event of a power interruption.
The totalizer can be reset via software.

• Flow conditioning for 1⁄2" to 1" based on upstream
length and sensor design
TEMPERATURE COMPENSATION
Thermal flow technology measures the mass flow rate
without the need for pressure and temperature correction.
However, there is a need to temperature compensate the
mass flow measurement for changes in gas properties due
to variations in process temperature. By measuring the gas
temperature, Model TA1 provides advanced temperature
compensation to correct for changes in properties of the
gas. The TA1 provides accurate flow measurement over
the entire specified temperature range of the instrument.
AREA COMPENSATION
FOR PIPE SIZE
Insertion of the sensor into a pipe reduces the flow
area, thus increasing the velocity for a given flow rate.
Magnetrol’s TA1 automatically compensates the flow
measurement based on actual area of the pipe. The
user simply enters the size or the area of the pipe, and
the instrument automatically compensates the flow
measurement.
AIR
EQUIVALENCY
Using historic air-gas calibration data, an air equivalency
calibration can be performed on select gases. Consult
Magnetrol for details and flow ranges.
A D D I T I O N A L
F E A T U R E S
TURNDOWN
The TA1 offers excellent low flow sensitivity and high
turndown ratios. The minimum detectable mass velocity
is 25 SFPM. This provides high turndown ratios of over
100 to 1, depending upon the maximum flow rate.
SELECTABLE
STP CONDITIONS
The TA1 directly measures mass flow of the gas at
standard pressure and temperature (STP) conditions.
Software permits the user to change STP conditions for
their own requirements.

Magnetrol offers two methods of removing the probe from
the pipe without having to shut down the process. The
Hot Tap Retractable Probe Assembly is designed to meet
API (American Petroleum Institute) standards. The less
demanding valve with compression fitting (part 0895218-001) will have some minor leakage when the probe
is removed or re-inserted and does not have the safety
cable to prevent “blow out” of the probe when removed
under pressure. RPA requires a probe with 3⁄4" NPT process
connection.
The valve with compression fitting uses a 1" NPT connection while the RPA uses a 11⁄2" NPT connection.
