Process
Suggested location
Gases
Above the gas line
Below but close to the
elevation of the process
connection.
Liquids
Level with or above the
process connection
2.4
Conduit / Cable Entries
There are no conduit/cable entries for the WPS-Series sensor.
2.5
Bracket mounting
There is no bracket mounting for the WPS-Series sensor. It is supported by the pipe fitting on the pressure sensor module.

Pressure Port
Materials:
•
316L Stainless Steel (pressure port body)
•
Hastelloy C-276 (diaphragm)
Process Connection:
•
Threads: 1/2" NPT Male thread and 1/4" NPT Female thread
•
Swivel: The WPS-Series sensor body will swivel 350 degrees with respect to the pressure port body, to optimize readablilty of the
LCD.

PROCESS INSERTION
3.1
Pressure Sensing
3.1.1 Piping
The actual piping arrangement will vary depending upon the process measurement requirements and the sensor model. Process connec-
tions are made to 1/4 inch NPT female or 1/2 inch NPT male connections in the sensor head of the sensor's body. They can be modified to
accept
3/4 inch NPT male through an optional pipe fitting
The most common type of pipe used is 1/2 inch schedule 80 steel pipe. Many piping arrangements use a three-valve manifold to connect
the process piping to the sensor. A manifold makes it easy to install and remove a sensor without interrupting the process. It also accom-
modates the installation of blow-down valves to clear debris from pressure lines to the sensor.
Another piping arrangement uses a block-off valve and a tee connector in the process piping to the sensor as shown below.
Explanation
The condensate drains away from the sensor.
This minimizes the static head effect of the condensate.
This requires a siphon to protect the sensor from process steam. The siphon retains
water as a "fill fluid."
adapter. Elbow fittings may be utilized as required.
