FIGURE 3 B142 TURBINE FLOW SENSORS 4 Form No B140 001 08 11 INSTALLATION Before installation the flow meter should be checked internally for foreign material and to be sure that the rotor spins freely Gas lines should also be cleared of all debris The flow meter must be installed with the flow indication arrow etched on the exterior of the meter body pointing in the correct direction of flow The preferred mounting orientation is to have the meter installed in horizontal piping with the pick up facing upward However the meter will function in any position While the flow meter body and magnetic pickup are sold as separate items in most instances they are ordered at the same time and come assembled from the factory If the magnetic pickup was not ordered with the meter body or replacement of the magnetic pickup becomes necessary all that is needed to install it is to thread the pickup into the pickup port until it is bottomed out Finger tightening is all that is required for proper installation The gas that is to be measured must be free from any large particles that may obstruct rotor from turn ing If particles are present a filter of at least 60 mesh 0 0092 clearance should be installed upstream before operation of the flow meter The preferred plumbing setup is one containing a bypass line Figure 4 that allows for meter inspection and repair without interrupting flow If a by pass line is not utilized it is important
