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.
2540 Hot-Tap sensor specifi cations and limitations depend on the lowest maximum rating of the components associated
with the system. For example, if a ball valve in the system is rated at a maximum 100 psi @ 175°F, you must limit 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 EPDM sensor fi tting O-rings.
Note: Pressure/temperature specifi cations refer to sensor performance in water. Certain chemical limitations may apply.
Chemical compatibility should be verifi ed.
1. Location of Fitting
Recommended sensor upstream/
downstream
mounting requirements.
2. Sensor Mounting Position
Vertical mounting is recommended for best overall performance. Mount at a maximum of 30°
when air bubbles are present. DO NOT mount on the bottom of the pipe when sediments are
present.
