Figure 3-11: Flow-through chamber meter installation
A. Optional temperature port
Note
• This flow-through chamber is a direct-insertion type chamber that does not have a
thermowell, and uses a 0.75 in (19 mm) Swagelok connection.
• The three compression fittings on the flow pockets (0.5 in (13 mm) drain, 0.75 in
(19 mm) temperature probe, and 1.5 in (38 mm) mounting nut for the meter) are
rated to above the working pressure of the flow pocket. The fittings may be Swagelok
or Parker.
3.4 Mount in an open tank (long-stem meter)
CAUTION
Only the safe area version of the long-stem meter can be mounted in an open tank.
Prerequisites
Verify the following conditions:
Flow
0.3 to 0.5 m/s (at the meter)
Important
If an agitator/stirrer is fitted inside the tank, then the flow
velocity inside the tank could be higher than 0.5m/s if the meter
is mounted close to the side wall. Mounting the meter closer the
center of the tank helps reduce the flow velocity seen by the
meter.
Viscosity • Up to 500 cP (with long tines)
• Up to 20,000 cP (with short tines)
Fluid temperature -40 °F (-40.0 °C) to 302 °F (150 °C)
