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 flow meter system installation. Diagram 1. Typical Flow Meter System Installation The...

See diagram 2 for straight pipe length requirement when there is altering device. Diagram 2. Number of Pipe Diameter (D=Diameter) Warning:Precaution for direct sunshine and rain when the meter is installed outside. Cavitation can be caused by entrained air, and it can seriously damage the rotor on a turbine flow meter. An amount higher than about 100 mg/l of entrained air or gas can produce error. In addition, cavitations can be caused by too little back pres on the flow meter. For turbine flow meters, you should provide a back pres (downstream pres) of at least 1.25 times the vapor pres, plus...
