Series 241 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 tapping operations. The following tapping instructions are general in nature and intended for guideline purposes only. Before installing the me- ter, review the mounting position and isolation value requirements given below.
Mounting Position
Allow clearance between the electronics enclosure top and any other ob- struction when the meter is fully retracted.
Isolation Valve Selection
An isolation valve is available as an option with Series 241 meters. If you supply the isolation valve, it must meet the following requirements:
1.A minimum valve bore di- ameter of 1.875 inches is re- quired, and the valve’s body size should be two inches. Normally, gate valves are used.
2.Verify that the valve’s body and flange rating are within the flow meter’s maximum operating pressure and tem- perature.

3.Choose an isolation valve with at least two inches existing between the flange face and the gate portion of the valve. This ensures that the flow meter’s sensor head will not interfere with the operation of the isolation valve.
