Caution: The 2540 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.
Fluid Conditions
Maximum operating pressure/temperature:
• Sensor with standard FPM sensor fi tting O-rings:
17 bar (250 psi) @ 82°C (180°F)
• Sensor with optional EPDM sensor fi tting O-rings:
17 bar (250 psi) @ 100°C (212°F)
Note: Pressure/temperature specifi cations refer to sensor
performance in water. Certain chemical limitations may apply.
Chemical compatibility should be verifi ed.
