Page 3: General Information
1. General Information This manual will assist you in installing, using and maintaining the Eletta flow meter. lt is your responsibility to make sure that all operators have access to adequate instructions about safe operating and maintenance procedure. For your safety, review the major warnings and cautions below before using your equipment. -
Page 4: Technical Data
Warning: NEVER insert the forklift`s fork, chains, wire slings or any other sharp object inside the flow tube for lifting or handling purpose. This could permanently damage the isolating liner and could render the meter inoperable. lf using a forklift, do not lift the detector on its body between the flanges. The housing could be accidentally dented and permanent damage could be caused to the internal coil assemblies. -

Page 7: Cautions For Installation
4. Cautions for Installation 4.1 Mounting Positions Pipes must be fully filled with liquids. It is essential that pipes remain fully filled at all times, otherwise flow rate indications may affected, and measurement errors may be caused. Avoid Air Bubbles. If air bubbles enter a measurement pipe, flow rate indications may be affected and measurement errors may be caused. -
Page 8: Required Lengths Of The Straight Runs
4.2. Required Lengths of the Straight Runs For optimum accuracy, it is required to provide sufficient inlet and outlet straight pipe runs. An equivalent to 5 diameters of straight pipe is required on the inlet side, and 2 diameters on the outlet side. There are no special requirements for standard concentric pipe reducers. -
Page 9: Connections
4.4 Connections Use a gasket between the meter flange and mating flange Determine the material of the gasket based on the operating conditions and type of fluid. Do not overtighten the flange bolts. This may cause the gaskets to be compressed into the flow stream and may decrease the accuracy of the meter. -
