Thermo-Flo™ AX1X with Compact Flow Controller
Application
Offered in liquid and gas sensor types, the general
purpose flow switch package provides reliable no
or low-flow detection of relatively clean non-coating
media with a 16A compact flow controller for pump or
process protection. Liquid examples includes water
and sulfuric acid. The optional flash alarm brings
attention to low-flow alarm conditions. Available in
Polypropylene-Ryton® and PVDF, the short flow
sensor is used in pipe or ducting from 1/2” to 1 1/2”,
and the long flow sensor is used in 2” and up. The flow
switch set point may be adjusted from 0.04 to 3 fps
in liquids, or 1 to 90 fps in gases for low-flow control.
The flow sensor is best applied in applications with
relatively constant temperature.

Thermo-Flo™ Flow Switch Fitting
Application
FT50
A common problem with metering pumps in flow applications is the characteristic of
the output flow. The pulsating flow makes it difficult for flow switches to get an
accurate and consistent flow rate. Often flow switches will not work because they
are not able to see a reliable flow output. The Flowline Pulse Point fitting is designed
to stabilize the pulsing flow for the Thermo-Flo flow switch. The cylindrical chamber
creates a mini-vortex that translates to a relatively constant flow. The Thermo-Flo
flow switch will be able to read the flow and provide an accurate and low-cost flow
switch. The Flowline Pulse Point fitting is ideal for use in metering pump
applications.
