Sarasota RTR900
2-4 User Guide for Sarasota ID900, FD900, & PD900 Gas Density Meters
The Sarasota RTR900 instrument retractor should be mounted on a ball or
gate location valve and have sufficient clearance to allow the Sarasota
ID900 and retractor to pass clearly through when the valve is open.
The isolation valve must be mounted squarely on the nozzle attached to the
system pipeline or tank and be clear of internal obstructions.
You will need the following equipment to install the Sarasota RTR900:
Allen key, 5 mm
●
Wrench, open-ended 1-1/5-inch and 1-5/16-inch AF
●
Wrench (2 off) to suit flange bolts
●
C wrench for gland nut (supplied)
●
Oil can containing good quality light machine oil (Shell Dexron II)
●
Fit the instrument retractor as follows:
1. Remove the amplifier box from the density meter.
2. Using the Allen headed bolts, fit the handwheel to retractorshaft.
3. Lightly lubricate the O-ring at the top of the jackscrew.
4. Insert the density meter through the nut of the pipe fitting and pushall
the way up to the stem. Take care when passing the O-ring.
5. Ensure the density meter body fits snugly against the nut and that the
cannon plug at the end of the density meter stem projects beyond the
retractor handwheel.
6. Finger-tighten the nut at the end of the retractor stem. Using a wrench,
tighten the nut 1-1/4 turns further. Check the density meter is held
firmly.
7. Turn the knob on the vent valve fully counterclockwise to allow the
lugs on the clamp nut to clear the valve handle. Undo the clamp nut
and remove it from the remainder of the seal housing along with the
retractor stem and instrument. Take care not to loose the Inconel C
ring on top of the seal housing.
