Chapter 2 Installation Series 220/221 Instruction Manual Unobstructed Flow Requirements Select an installation site that will minimize possible distortion in the flow profile. Valves, elbows, control valves and other piping components may cause flow disturbances.
Series 220/221 Instruction Manual Chapter 2 Installation Series 220 In-Line Flow Meter Installation Install the Series 220 In-Line Flow Me ter between two conventional pipe flanges as shown in Figures 2-3 and 2-4. Table 2-1 provides the recom- mended minim um stud bolt lengths for wafer-style meter body size and dif- ferent flange ratings.
Chapter 2 Installation Series 220/221 Instruction Manual Wafer-Style Flow Meter Installation Install the wafer-style meter between two conventional pipe flanges of the same nominal size as the flow m eter. If the process fluid is a liquid, make sure the meter is located where the pipe is always full.
Series 220/221 Instruction Manual Chapter 2 Installation Flange-Style Flow Meter Installation Install the flange-style meter between two conventional pipe flanges of the same nominal size as the flow m eter. If the process fluid is a liquid, make sure the meter is located where the pipe is always full.
Chapter 2 Installation Series 220/221 Instruction Manual Series 221 Insertion Flow Meter Installation Prepare the pipeline for installation using either a cold tap or hot tap method described on the following pages. Refer to a standard code for all pipe tap- ping operations.
Series 220/221 Instruction Manual Chapter 2 Installation Cold Tap Guidelines Refer to a standard code for all pi pe tapping operations. The following tap- ping instructions are general in nature and intended for guideline purposes only.
Chapter 2 Installation Series 220/221 Instruction Manual Hot Tap Guidelines Warning! Hot tapping must be performed by a trained professional. US. regula- tions often require a hot tap permit. The manufac- turer of the hot tap equipment and/or the contractor performing the hot tap is responsible for providing proof of such a permit.
Series 220/221 Instruction Manual Chapter 2 Installation Flow Meter Insertion The sensor head must be properly positioned in the pipe. For this reason, it is important that insertion length calculations are carefully followed. A sensor probe inserted at the wrong depth in the pipe will result in inaccurate readings.
Chapter 2 Installation Series 220/221 Instruction Manual Installing Flow Meters with a Compression Connection* Use the following formula to determine insertion length for flow m eters (NPT and flanged) with a compression process connection. The installation procedure is given on the next page.
