Series 240 In-Line Flow Meter Installation

Install the Series 240 In-Line Flow Meter between two conventional pipe flanges as shown in Figures 2-3 and 2-4. Table 2-1 provides the recom- mended minimum stud bolt lengths for wafer-style meter body size and different flange ratings.

The meter inside diameter is equal to the same size nominal pipe ID in schedule 80. For example, a 2” meter has an ID of 1.939” (2” schedule 80). Do not install the meter in a pipe with an inside diameter smaller than the inside diameter of the meter. For schedule 160 and higher pipe, a special meter is required. Consult the factory before pur- chasing the meter.

Series 240 Meters require customer-supplied gaskets. When selecting gasket material make sure that it is compatible with the process fluid and pressure ratings of the specific installation. Verify that the inside diame- ter of the gasket is larger than the inside diameter of the flow meter and adjacent piping. If the gasket material extends into the flow stream, it will disturb the flow and cause inaccurate measurements.

Table 2-1. Minimum Recommended Stud Bolt Lengths for Wafer Meters

The required bolt load for sealing the gasket joint is affected by several application-dependent factors, therefore the required torque for each ap- plication may be different. Refer to the ASME Pressure Vessel Code guidelines for bolt tightening standards.
