TSI Incorporated 4140, Operation And Service Manual

Page: 23 / 26

Specifications 15
Notes:
1 Accuracy stated at standard conditions of 21.1°C and 101.3 kPa.

Add an additional 0.0003 Std L/min or 0.075% of reading, whichever
is greater, per 1°C away from standard conditions when operating
within the range of 0°C to 50°C.

Add an additional 0.015% of reading per 1 kPa above 101.3 kPa or

Add an additional 0.022% of reading per 1 kPa below 101.3 kPa
when operating within the pressure range of 70 kPa to 101.3 kPa.
2 Accuracy stated with gas temperature and flow body temperature within
±10°C of one another.
3 Accuracy stated measuring dry gas (less than 10% R.H.).
4 Includes ±0.5% of reading repeatability.
5 Volumetric flow rate is calculated from the mass flow measurement. Add
an additional 0.25% of reading to the flow accuracy to account for the
uncertainty in measuring gas temperature and pressure.
6 For analog output, accuracy offset increases from 0.005 to .02 Std L/min.
7 Add uncertainty of 0.2 kPa for every 10°C away from 21.1°C.
