4. Once fluid starts to come from the bleed valve, stop opening the main
line valve. Shut the vent valve tightly.
5. Check:
a.
The joints between the seal housing and valve for fluid leaks.
b. For fluid weeping past the gland, and tighten the gland further if
necessary.
c. For fluid leaks passing up the stem of the instrument inside the
threaded retractor tube.
d. For leaks past the Inconel C ring. If there are leaks, ensure the
clamp ring is tight (330 Nm/250 lbf.ft). If this does not stop the
leakage, steps 1 through 4 will need to be reversed, and the C ring
will need to be replaced. Make sure the mating surfaces are free
from grit, dirt, or damage.
Insertion
1. Remove the amplifier box on the end of the density meterstem.
2. Check the cleanliness of the retractor thread.
3. If the thread is excessively dirty, clean it using an appropriate solvent
(clean kerosene). Once the thread is clean, liberally apply light machine
oil to the thread, especially at the point where it enters the gland nut.
4. Insert the density meter into the line by rotating the handwheel
clockwise. Check for leakage around the screw head as the insertion is
performed.
5. Once insertion is completed to the required depth, check the
orientation of the density meter and adjust as necessary.
6. Protect any exposed threads on the retractor by coating with waterproof
grease.
7. Reconnect all electrical connections by fitting the amplifier box to the
top of the density meter stem. Ensure that the cable ends and terminal
identifications correspond.
8. Check that the flow arrow on the amplifier aligns with pipe flow
direction for the density meterinstallation.
9. Check for leakage and make corrections asnecessary.
