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,...
