2.3.6 FLOW-THROUGH CHAMBER INSTALLATION
This chamber is fabricated by Solartron, and is available with either weld prepared ends or
with flange or compression fittings for connection into the process pipe lines. It is available
with 1” or 2” inlet and outlet pipes.
Note: The length of the inlet and outlet pipes must not be altered, otherwise the
temperature response and stability of the fitting may be adversely affected.
Conditions:
Flow: constant, between 10 and 30 l/min
Viscosity limit: Up to 20 000cP
Temperature: -50 to +200°C
Pressure: 70 bar at 204°C, subject to process connections.
The PT100 is a direct insertion type, without a thermowell, and uses a ¾" Swagelok
connection.

1" Flow-through chamber
For optimum results the fluid flowing through the chamber should be homogeneous (plug
flow). This can be achieved by installing a static mixer immediately before the chamber.
Contact Solartron for advice about using flow-through chambers in hygienic applications.
