Signet 50 High Performance Flow Sensor English *3-50.090* 3-50.090 C 05/06 English SAFETY INSTRUCTIONS 1. Do not remove from pressurized lines.. Do not exceed maximum temperature/pressure specifi cations. 3. Wear safety goggles or faceshield during installation/service.. Do not alter product construction. 5. Apply sealant or PTFE tape to threads, inspecting threads to ensure integrity. Do not install a with damaged threads. Pipe fi ttings MUST be installed by a certifi ed welder only. Signet will not assume liability of any kind for improper fi tting installations. 50 Hot-Tap specifi cations and limitations depend on the lowest maximum rating of the components associated with the system. a ball valve, a component of the system, is rated at a maximum 100 psi @ 175 F, limiting the entire system's maximum pressure/temperature rating to 100 psi @ 175 F. All higher maximum specifi cations MUST yield to the component with the lowest maximum specifi cation. Maximum Operating Pressure/Temperature: 17 bar (50 psi) @ 8 C (180 F) with standard Viton fi tting O-rings. 17 bar (50 psi) @ 100 C ( 1 F) with optional EPR fi tting O-rings. 1.

5 3 1 A 6 5 3 1 B 5.5 Calculating the H Dimension Before installing the some critical dimensions must be established (for Hot-Tap installations, we assume the pipe dimensions are known). The rotor shaft must be located 10% inside the pipe I.D. to ensure accurate calibration capability. To accomplish this, the "H" dimension is measured from the outside surface of the pipe to the bottom of the fl ange. Nominal "H" dimensions for standard pipes are listed in section 10. For non-standard pipe dimensions, calculate the "H" dimension using the formula listed below. Your pipe's wall thickness and inside diameter (I.D.) is required for the "H" dimension calculation. The 6 inch ruler (included) may be used to measure your pipe I.D. and wall thickness up to 5 inches (standard s only). correct wall thickness 6 5 5 3 3 1 1 A B 6 5 5 3 3 1 1 incorrect pipe I.D.

In other words, the Hot-Tap system is only as strong as its weakest link. For example, a ball valve, a component of the system, is rated at a maximum 100 psi @ 175 F, limiting the entire system's maximum pressure/temperature rating to 100 psi @ 175 F. All higher maximum specifi cations MUST yield to the component with the lowest maximum specifi cation. Note: Pressure/temperature specifi cations refer to performance in water. Certain chemical limitations may apply. Chemical compatibility should be verifi ed.
