3) Mounting the Control Panel:

Mounting Requirements:• Select a location that is easily accessible at grade level.• Mounting holes are provided for easy installation.• The Probe Assembly must be mounted next to the analyzer – separation is limited by

10 linear feet of fiber.• Shade is required if mounting outdoors where ambient temps can exceed 90⁰ F.• Do not mount the analyzer in such a way to make it difficult to operate the

customer-provided electrical disconnect device (witch, breaker or other)

Antenna Connection:1. 16dB Antenna is provided along with a 90 degree fitting.2. Attach Antenna to the fitting on the upper left of the Analyzer Panel using the 90

degree fitting (see Figure 3 for location of the fitting).

1. Fiber Optic Connection:2. The Fiber is passed through the flex conduit/liquid

tight fittings on the bottom of the analyzer control panel. Customer provides flex conduit.

3. Send Fibers will be labeled with 2” Red Shrink Tube reading “SEND”.

4. Receive Fibers will be labeled with 2” Yellow Shrink Tube reading “RECEIVE”.

5. Pull the fibers through the flex conduit, and let the excess hang coiled up under the analyzer until ready to connect to the probe assembly.

6. Leave the caps on the end of the fiber. Do not let the fiber drag on the ground.

7. See Section 5 for instructions to connect the fiber to the probe assembly


8

Pass-through for Electrical Wires:• The Verax Control Panel is shipped without holes or wire ways for most of the

incoming electrical service or fiber connections. The only pre-positioned holes are:• The Antenna fitting (top left), and• Two fittings for the fiber (bottom left)

• Additional wire pass-throughs will need to be installed by the customer. The placement of these holes is left up to the customer’s installation teams in order to provide maximum flexibility to bring the cables and fiber from below or above, and attach them to the Verax Control Panels with a sufficient size conduit or fitting.

• All connections or fittings chosen by the customer should by rated for Type 4 enclosure.

• After the wires and fibers are run, all ports and pass-throughs must be plugged with duct putty or some other standard industry practice to assure the sealed integrity of the enclosure.

• The customer must plan for the following cables when choosing the size and placement of ports on the Verax Control Panel:

• One Incoming Electrical Cable• One Incoming communications Cable • One RTD cable from the probe assembly• One Transducer cable from the probe assembly

• Read instructions in Section 6 regarding where these fibers/cables attach inside the control panel before you start cutting holes.

• The customer is responsible to protect the inside of the control panel when cutting or punching holes for the wire way. DO NOT ALLOW METAL SHAVINGS TO FALL ON THE ELECTRICAL CONNECTIONS OR COMPONENTS INSIDE THE CONTROL PANEL.

• Contact your local JP3 sales representative to discuss options

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.

5) Probe Assembly to Control Panel Connections

Connect Fiber Optics to Probe Assembly:

Warning – Read Carefully• Fiber optic cable is extremely sensitive to sharp bend angles and contamination.

Handle very carefully to avoid kinks and keep the ends capped until ready to attach to the probes.

• Maintain a minimum 7” bend radius when running/routing the fiber from control box to probe assembly

• It is recommended that the fiber optic cable be run in it’s own dedicated conduit, or elevated cable trays. Do not place fiber in ground level open cable trays where it can be stepped on.

• Keep the fiber ends capped until you a are ready to connect the ends.

Attach Fiber to Probe Assembly:1. Open the conduit housing on the probe assembly2. Install the fiber using LT50 fittings and flex conduit at either end of the probe assembly

(see Figure 6). The flex conduit approach offers the best protection for the fiber.3. Connect the fiber to the back of the probe inside the conduit housing by screwing the

fiber end onto the threaded probe connection. (see Figure 7)

4. DO NOT THROW AWAY THE KNURLED CAPS. These should be left in the conduit housing to be used to protect fiber and probe connections when disconnected during servicing.

5 Replace conduit housing cover
