FPDM1000 SERIES Positive Displacement Mechanical Flowmeters
To the owner: IMPORTANT INFORMATION Thank you for purchasing an OMEGA FPDM Series Flowmeter. Please take a few minutes to read through the manual before installing and operating your meter. If you have any problems with the meter, refer to the Maintenance and Troubleshooting sections of the manual. This manual contains connection and operating instructions for the OMEGA FPDM Series meters with mechanical displays.
Figure 2 INSTALLATION 1. OMEGA recommends that when setting up pipework for meter installations, a bypass line be included in the design. This provides the facility for a meter to be removed for maintenance without interrupting production. (See Figure 1) ➧ ➧ Figure 1 Bypass Line RIGHT RIGHT Flow Inlet Strainer Flow Outlet WRONG ➧ NOTE: Incorrect installation can cause premature wear of meter components 7. Do not overtighten meter connections. 2. Use thread sealant on all pipe threads. 3.
OPERATION When fluid passes through the meter, the rotors turn. The gear located on top of one of the rotors drives the mechanical registers gear train which provides an accurate readout. SERVICE INSTRUCTIONS Disassembly: Ensure that the fluid supply to the meter is disconnected, and the line pressure is released before disassembly. Refer to the exploded parts diagram on page 6. 1. Remove the four screws located on the face of the register. Then remove the faceplate cover including register assembly. 2.
Check rotor operation by turning either of the rotors. If the rotors are not in mesh correctly or do not move freely, remove one of the rotors and replace it correctly at 90 degrees to the other rotor. Recheck the operation of the rotors. 4. Inspect the gears in the meter cap for wear. Replace if required - refer to spare parts on page 6. 5. Replace the O-ring into the groove in the meter cap. If the O-ring has been distorted or is damaged in any way, replace it with a new part. 6. Replace the meter cap.
TROUBLESHOOTING Symptom Probable Cause Corrective Action FLUID WILL NOT FLOW THROUGH THE METER 1. Foreign matter blocking rotors Dismantle meter, clean rotors. Strainer must be fitted in-line. 2. Line strainer blocked Clean strainer. 3. Damaged rotors Replace rotors. Strainer must be fitted in-line. 4. Meter connections overtightened Re-adjust connections. 5. Fluid is too viscous See specifications for maximum viscosity. 1. Strainer is partially blocked Clean strainer. 2.
