To get the best results from the instrument, the sensor should be located 20 pipe diameters down
stream from any flow disturbance (valve, pipe elbow, etc.) and 10 pipe diameters upstream from
any disturbance.
The outside of the instrument has tags which show the model number, tag number (if noted on the
customer’s order) and serial number along with other important safety information. Compare this
information with the appropriate pipe installation drawings and calibration sheets to verify the
instrument is the correct configuration.
Pre-Installation
2. Quick Start Guide
The recommended installation/troubleshooting tools are:
1 ea. Open-ended wrench to fit the NPT connection
1 ea. Open-ended wrench to fit the flanged fitting nuts and bolts
1 ea. Small flat blade screw driver for manipulating potentiometers
1 ea. Medium flat blade screwdriver for tightening connections
1 ea. Medium phillips head screwdriver for tightening connections
1 ea. 3 mm Allen wrench
1 ea. Measuring tape for proper flow element placement
1 ea. DVM for Ohm/Voltage measurements
Verify that the serial numbers on the enclosure(s) tag(s), flow element and electronics match. The
instrument may not work if the serial numbers are miss-matched.
Install the flow element, with the flow arrow pointing in the direction of media flow. The element
should be in the center line of the process pipe or rectangular duct as shown above.
If the NPT option is used, see Page 13 for installation instructions.
If the flanged option is used, see Page 13 for installation instructions.
If the GF92 in-line option is used, see Page 14 for installation instructions.
NOTE: ST98 type flow element only inserts 0.50 inches past centerline. See VeriCal System
Diagram on page 54.
