Help Text for Number of Tubes:
Model P style rotameters are available in 1, 2, 3, 4, 5, and 6 flow tube configurations.
Selecting 2 or more flow tubes, offers the convenience and simplicity of having more than one flow tube in a single rotameter unit.
Multiple flow tube configurations also offer the option of having a manifold at the inlet or outlet.
Just like single flow tube rotameters, multiple tube rotameters are available with either a 65 mm or 150 mm flow tube size.

Help Text for Tube Size:
The main reason for selecting a 65 mm scale over a 150 mm scale is size constraints.
Your application may require a compact size flow meter. Selection of a 150mm scale size offers better resolution.

Help Text for Housing Material:
Housing Material ::
Model P rotameters are available with Aluminum, Brass, or
316 Stainless Steel housing material and fittings. The choice of housing material
will depend on the type of fluid (gas or liquid) being used with the rotameter.

Help Text for Seals:
Seals ::
As with your choice of housing material, model P rotameters
are available with Buna-N, EPR, PTFE/Kalrez®, and Viton-A® seals
and o-rings.
With Aluminum or Brass housing material, Buna-N is the default
seal material (Viton-A® for flow tube packings). Stainless steel housing
material has Viton-A® as it s default.
You may order in any desired
configuration (prices may vary). The choice of seals will depend on the
type of fluid (gas or liquid) being used with the rotameter.

Fittings ::
There are a variety of end fittings available for you to choose
from. 1/8 inch FNPT fittings (inlet and outlet) are standard on all model
P rotameters.

Manifold:
|
None (Standard) Bottom (inlet) Top (outlet) |
|
Help Text for Manifold:
Manifold ::
Selection of 2, 3, 4, 5, and 6 flow tube configurations offers you the choice
of no manifold, manifold
at the top (outlet) or manifold at the bottom
(inlet).
The no manifold option offers isolated parallel
channels for flow measurement and control.
Selecting manifold at the top (outlet), allows
for independent fluid inputs and a single common exhaust.
Selecting manifold at the bottom (inlet), provides
for a single common fluid input and multiple isolated outputs.
|
|
Tube end-seals:
|
Viton-A®
Buna-N
|
|
The configuration above, of housing material and seals uses Viton-A for the flow tube end-seals (packings) by default. All other seals (o-rings) are as selected. If your application requires otherwise, you may change this to Buna-N by making that selection here.
