SAFETY INSTRUCTIONS
1. Do not remove from pressurized lines.
2. Do not exceed maximum temperature/pressure specifi cations.
3. Wear safety goggles or faceshield during installation/service.
4. Do not alter product construction.
5. Apply sealant or PTFE tape to sensor threads, inspecting threads to ensure integrity.
Do not install a sensor 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.
2517 Hot-Tap sensor 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 (250 psi) @ 82°C (180°F) with standard FPM sensor fi tting O-rings.
• 17 bar (250 psi) @ 100°C ( 212°F) with optional EPR sensor fi tting O-rings.

5.5 Calculating the H Dimension
Before installing the sensor 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 sensor fl ange.
Nominal "H" dimensions for standard pipes are listed here. 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 sensors only).

Standards and Approvals
• Manufactured under ISO 9001:2000 for Quality and
ISO 14001:1996 for Environmental Management
• FM approved, CE.
Caution: The 2517 Hot-Tap system's overall
specifi cations and limitations depend on the lowest
maximum rating of the components associated with the
system. 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 sensor
performance in water. Certain chemical limitations may apply.
Chemical compatibilityshould be verifi ed.
