MEASURE FLOW, PRESSURE,

AND TEMPERATURE…

ALL IN ONE INSTRUMENT!

Designed for Performance

TSI thermal mass owmeters incorporate a proprietary platinum lm

sensor design for measuring gas ows in applications demanding fast

response and high accuracy over a wide ow range. TSI owmeters have

turn-down ratios greater than 1000:1 due to our thermal ow sensing

technology and extensive gas calibration process. The TSI 4000 Series

was designed for ultra-low pressure loss to minimize any undesirable

eects the owmeter can have on the readings when installed in-circuit.

Accurate

A owmeter specied as ±2% of full scale
is most accurate at full scale. If full scale
is 300 L/min, then the uncertainty for all
readings is ±6 L/min. TSI owmeters are
specied as ±2% of reading and have an
uncertainty of ±2% of the actual reading
from full scale all the way down to a
specied lower limit. TSI owmeters,
therefore, provide dependable accuracy
over a wide range of ow rates. One TSI
owmeter covers the same range as three
or more “percent of full scale” devices...
with better accuracy at all points!

Fast

Fast 4 millisecond response ensures accuracy
in uctuating ows. This fast response is
ideal for closed-loop control systems and
integrated volume measurements. Pressure
and temperature measurements are
also extremely fast.

Low Pressure Drop

Low pressure drop minimizes ow circuit back
pressure and its impact on the system under test.
