Part No. FU-CT-*I (* represents number of channels up to 3, ie. FU-CT-1I) ® is designed for easy installation, convenient calibration, and very low maintenance. FuelCheck The following chapters will describe the principle of operation, installation considerations, and system calibration and operation. Figure 1 FuelCheck System Architecture...
(lost) from the lens is directly proportional to the index of refraction of the fluid in which the probe lens is immersed. Thus, the higher the fluid’s index of refraction, the less ® amount of light is returned to the detector in the FuelCheck Controller. FuelCheck Operating Principle FuelCheck 1.
Figure 3 the probe is moved or FuelCheck Probe installed in pipeline crimped at the wrong loca- tion on the probe body. The probe incorporates a safety stop which is an 11/16” OD upset welded onto the probe body to prevent the probe from passing through the process insertion fit- ting.
Some general recommendations for probe location and orientation are as follows: Try to mount the FuelCheck probe in a location where the pipe is always full, even when the line is not flowing.

The probe should always be installed in close proximity to a reliable pressure gauge or the pres- ® sure must be known when performing these operations. When installing a FuelCheck Probe for the first time, the following procedures must be followed. It is imperative that all client safety procedures be followed explicitly, and that engineering specifications (i.e., threaded connection...
® Initial FuelCheck SAE (standard) probe Installation Low Pressure Installation IMPORTANT: Note line pressure. If over 300 PSI (2000 kPa) follow instructions for high- pressure installation. NOTE - Make Initial measurement “A” before starting to install probe into pipeline. SAE/MS STRAIGHT THREAD...

Insertion Length (L) as follows: L = A + ½ wall thickness 3. Clean and lubricate exposed probe body using light machine oil or a grease to avoid damag- ing o-ring seals. 4. Tighten the Hex cap on the Process Insertion Fitting. Move the Process Insertion Fitting up the probe body until the exact distance calculated in Step 2 is reached.

7. Verify Process Insertion Fitting is snug against safety stop by pulling upward on the probe body. Pull Upward Figure 11 Safety stop 8. Open valve slowly and check for leaks. Figure 12 Figure 9 Check for leaks 9. Using low-pressure probe insertion handle, push probe into pipeline (figure 6) until indelible mark is aligned with top of the Process Insertion Fitting.

10. Again, check entire fixture for leaks and attach Warning Placard (Figure 9) to valve handle and probe body using cable tie.

® FUELCHECK PROBE REMOVAL WITH (LINE PRESSURE < 300 PSI) Positively ascertain line pressure is less than 300 PSI or 2000 KPA. NOTE: At 300 PSI, the upward force on the probe will be about 60 lb. Attach low pressure inser- tion handle to probe.

4. Place a backup wrench on the Insertion Tool Adapter. Remove the Process Insertion Fitting from the Insertion Tool Adapter taking care not to spill any process fluid. The use of hydrocarbon absorbing padding is suggested to prevent environmental contamination. Be sure to dispose of contaminated padding properly.
® FUELCHECK PROBE REINSERTION with (PRESSURE <300 PSI) Positively ascertain line pressure is less than 300 PSI or 2000 KPA. 1. Make sure probe is fully retracted (safety stop against bottom of insertion fitting). Install probe onto Process Insertion Fitting and tighten insertion fitting to valve.

7. Reattach Warning Placard to valve han- dle and probe body using cable tie. •DO NOT CLOSE VALVE •DO NOT LOOSEN FITTINGS FuelCheck™ Probe installed through valve please refer to FuelCheck™ Operating Manual before attempting to remove FuelCheck™ Probe Figure 23 Reattach warning placard...
8. On short fiber runs to be undertaken inside conduit deemed to be in good condition and not containing any other cables, the fiberoptic cable can be supplied pre-connectorized. It is rec- ommended that the conduit run be carefully measured and that sufficient excess be allowed ® for easy connection to the FuelCheck Controller.

Spread open the slit and place the stopper over the fiberoptic interconnect cable and the ® probe cable as shown. Attach the ST mating sleeve to the ST connector on FuelCheck the interconnect cable. Figure 24 Insert fiber in stopper b) Attach stabilizer tube to stopper as shown leaving the connector protruding from the end.
Page 20
d) Connect the probe’s ST connector to the mating sleeve. Figure 27 Attach mating sleeve to FO connectors e) Draw the stabilizer tube assemble together by carefully pulling the interconnect cable fiber through the holes in the stopper. Make sure the stoppers are snug in the stabilizer tube and the fibers are straight.

4. Press the MODE button. When depressed, the RUN indicator will turn off and the CH 1 indicator will start flashing. The Signal Conditioner is ready to begin the setup. 5. Place the probe in the fluid to be used as the High set point, making sure the signal is stable by observing the dBm display, it may be necessary to agitate the probe in the fluid to make sure the sensor is properly wetted.

When the fluid in the Pipeline changes to Diesel, perform the same operation but do the se- tup when the CH 1 indicator is flashing for the High setting. This can be done whenever the fluid changes in the Pipeline and the reading may require a change.
For certain applications, it may be advantageous to normalize the refractive index output to stan- dard temperature (60°F). During the development of FuelCheck, a series of flow loop measurements was made at various fluid temperatures. From the experimental data, the following conclusion can be made: = V+(0.01374(60-T))
