Flow Tracker Series 1000/2000
Maintenance and Recalibration
The Agilent Flow Tracker Series flowmeters require minimal
maintenance. With the exception of the sampling pump in the
2000 Series, the Flow Tracker flowmeters have no moving parts.
The single most important thing that affects the life and
accuracy of this device is the quality of the gas being measured.
It is designed to measure CLEAN, DRY, NON-CORROSIVE gases.
Cleaning
The Flow Tracker flowmeters require no periodic cleaning. If
necessary, clean the outside of the flowmeter with a soft dry
rag. Be sure to avoid any excess moisture or solvents.
Replacing the batteries
To replace old or worn batteries:
1
Remove the flexible boot from the flowmeter housing.
2
Remove all three screws from the back cover.
3
Carefully remove the back cover to expose the batteries.
4
Carefully remove the old batteries.
5
Install new batteries as shown on the back cover.
6
Replace the back cover and re-install the three screws.
7
Replace the flexible boot, pushing the bottom end of the
flowmeter into the boot first.
Recalibration
The recommended period for recalibration is two years or less,
although the calibration interval can be shortened to meet
individual requirements. Providing that the CLEAN, DRY, and
N O T E
A 20-micron filter mounted upstream of the flowmeter is highly
recommended. Moisture, oil, and other contaminates can affect the
laminar flow elements and/or reduce the area that is used to calculate the
flow rate. This directly affects the accuracy.
