Flow Readout
Thermo Scientific
Flow control for P 1, P 2, T0 and T 1 pumps
on ThermoFlex900s - 5000s is achieved using
Readout
a 3-way valve plumbed between the standard
process outlet and the process inlet on the
rear of the chiller. Use the auxiliary process
outlet at the top left of the rear of the chiller
as a connection point. The connections are
½" FNPT. See Figure 5-8.
ThermoFlex3500s and 5000s with P 3 and P 4
pumps use a 2-way valve located on the rear
of the chiller. The connections are
3/4" FNPT. See Figure 5-9.
ThermoFlex7500s and 10000s with P 2 -
P 5 and T 5 (see next page) pumps use a
valve located on the rear of the chiller. The
connections are 1/2" for P 2, 1" FNPT for P 3
and P 5. See Figure 5-9.
Use the controller's Status Display to view
the flow rate. Turn the valve handle until the
desired rate is displayed.
Note The valve is sensitive to slight
adjustments.
The pressure relief with flow readout works
just like the pressure relief Valve discussed on
the previous page. It allows you to control the
pressure going to your application.
This valve is plumbed into the chiller's auxiliary
port, allowing you to also monitor the flow rate
to your application using the controller's Status
Display.
The valve's outlet connection is ½" FNPT.
See Figure 5-10.
