12 Micro Motion 7827 Digital Viscosity Meter
Installation (Short Stem)
Figure 2-2 Free stream 1.5" Swagelock fitting
The installation will conform generally to Schedule 40 pressure ratings. The weldolet fabrication is
rated to 100 Bar at ambient temperature.
Note: Correct installation and pressure testing of the fitting is the responsibility of the user.
2.3.5 T-piece installation
Conditions:
• Flow: 0.5 to 3.0 m/s (at the pipe wall)
• Viscosity: 0.5 to 100 cP
• Temperature: -50 °C to 200 °C (–58 °F to 392 °F)
[-40 °C to 200 °C (-40 °F to 392 °F) in hazardous areas]
The thermal mass of the flanges may affect the response time of the meter to temperature changes.
Flow velocity at the pipe wall and fluid viscosity must be within the limits shown to ensure that the
fluid within the pocket is refreshed in a timely manner. This installation will not respond as rapidly as
the free-stream installation to step changes in viscosity.
The view shown is a schematic to show the dimensions of the side pocket, which is fabricated by the
end user.
