Figure 4-1. Low Flow Transducer LFE Cleaning

Caution!

Removing or re- positioning the LFE may alter the calibration..

Low Flow Transducers:

The LFE is accessed by unscrewing the main inlet fitting and re- moving it from the flow body. The LFE is screwed into the inlet fitting, which has been specially machined for this purpose. To ac- cess the components:

1.Remove the unit from the system.

2.The inlet filter screen is held in place in the inlet fitting by the LFE. Disassemble by holding the fitting steady with a wrench and unscrewing the LFE with a medium flat-tipped screw- driver.

3.Remove the LFE assembly taking care not to bend the inlet screen. Inspect the sealing O-ring and replace if necessary. In- spect the inlet screen and replace if corroded or damaged. Light to medium particulate contamination can be cleaned by back washing with a suitable solvent. Air dry thoroughly.

4.Inspect the LFE for damage and replace if necessary. Replace- ment of the LFE or inlet screen requires transducer re- calibration.

5.Re-assemble components. When the transducer is re-installed in the system, leak test the connection.

6. Check transducer calibration.
