Replacing a Flow Sensor
92 Troubleshooting & Maintenance Guide
Replacing a flow sensor requires these tools and materials:
Tools
• #2 Phillips head screw driver
• 2.5 mm hex wrench or ball driver
IMPORTANT EASY-nLC 1200 flow sensors are compatible with EASY-nLC
1000. EASY-nLC 1000 flow sensors are not compatible with EASY-nLC 1200.
Only flow sensors whose serial number is larger than 1528-XXXXX can be used
on EASY-nLC 1200 systems (software plausibility check).
CAUTION Wear powder-free gloves and safety glasses when handling parts of the LC system
that come into contact with solvents.
To replace a flow sensor follow these procedures:
1. "To remove an flow sensor,"
2. "To install an flow sensor"
❖ To remove an flow sensor
1. Close down the EASY-nLC system, and turn off the power to the instrument (see
"Closing Down the EASY-nLC Instrument"
2. Using a #2 Phillips head screwdriver, make a quarter-turn to loosen the three captive
screws that secure the right side panel to the instrument housing. Then remove the panel.
3. Remove the nanoViper tubing from the inlet and outlet of the flow sensor.
Figure 73 shows the flow sensors mounted behind the bracket. The flow direction is
labeled on the bracket.
