4) Mounting the Probe Assembly:
Placement:
•The Probe Assembly are typically mounted to a unistrut frame, or other solid structure
•Probes should be accessible at grade level.
Pressure and Temp Rating:
•All probe windows and probe assemblies are tested to 1500 psi
•Operational temperature range: -29C to 50C (-20⁰ F to 122⁰F).
Bypass Probe Configuration:
•For a bypass probe assembly, the customer taps into the process stream they want to
monitor, plumbs the fluid to the inlet on probe assembly, and back to the process
stream. (see Figure 4 on the next page)
•It is highly recommended that the customer supply a stinger at the inlet and return of
the pipe you are monitoring in order to pull fluid from the center of the pipe.
•Either ½” or ¼” Swagelok fittings are supplied on the inlet and return ports of the probe
assembly. Customer supplies ¼” or ½” stainless steel tubing as dictated by the fittings
supplied on the probe assembly.
•½” is typical for liquids
•¼” is typical for gas
•The customer must assure sufficient flow of liquid or gas over the probe windows by
providing a pressure drop of at least 1 psi from inlet to outlet. Choosing the correct
inlet and return points on the process pipe is critical to assure flow. Often choosing
inlet and return points such that flanges, valves, meters or similar instruments are
located between these two points is sufficient to provide the necessary bypass
pressure differential.
•Actual Installation details vary by location and application; consult with JP3 Sales
representative to discuss options.
•When using a heater blanket with the probe assembly, 120VAC, 2 Amp service is
required. The junction box must be within 4 feet of the probe assembly.
