FLR Flow Transmitter Installation & Programming Instructions
Inspection
1.Frequent inspection should be made. The envi- ronment and frequency of use should determine a schedule for maintenance checks. It is recom- mended that it should be at least once a year.
2.Perform visual, electrical, and mechanical checks on all components on a regular basis.
3.Visually check for undue heating evidence such as discoloration of wires or other components, damaged or worn parts, or leakage evidence such as water or corrosion in the interior.
4.Electrically check to make sure that all connec- tions are clean and tight and that the device is wired properly.
VI. TROUBLESHOOTING
No LCD display
•For
•Check polarity of the current loop connections for proper orientation.
•For
•Check polarity of the supply voltage.
No rate or total displayed
•Check flow meter cone for debris. Cone should move inside the tube freely.
•Check setup programming of flow meter.
Unstable Flow Reading
•This usually indicates pulsing or oscillation in the actual flow. Increase the DAMPING parameter to increase the filtering in order to provide a more stable display reading.

Application Information – Liquid
Viscosity Effect (SUS/cSt)
The design utilizes a precision machined,

models of each transmitter size provide good accuracy over a viscosity range of 40 to 500 SUS (4.2 to 109 cSt).
Density Effect (specific gravity)
Any fluid density change from stated standards has a proportionate effect on transmitter accuracy. Corrections for more or less dense fluids can be made to standard scales using the following correction fac- tor:
