Model Selection Nominal diameter(mm) Meter material Impeller material Explosion-proof grade CAUTIONS FOR INSTALLATION Mounting Positions Turbine flow meters should be installed at the place in compliance with the requirements below: •Easy maintenance •No vibration •No electromagnetic interface •Away from heat source Mounting Orientation All turbine flow meters are designed to measure flow in only one direction. The direction is indicated by the arrow on the body. Required Lengths of Straight Runs Flow altering device such as elbows, valves and reducers can affect accuracy. See diagram 1 for typical...

See diagram 2 for straight pipe length requirement when there is altering device. Thread Connec�ons 1.To protect against leakage, seal all threads with an appropriate sealing compound. Make the sealing compound does not intrude into the flow path. 2.Make the arrow on the outlet is pointed in the direc�on of theflow. 3.Tighten the turbine onto the fi�ngs. Use a wrench only on wrenchflats. Flange Connec�ons For standard product, the flange follows GB/T 9119-2000 (ISO 7005-1) RF (Raised Face). Note: flange can be customized following other criteria. Use a gasket between the meter flange and ma�ng flange....
