5.12.4 Installing a measuring tape to a medium/high-pressure tank
• Never bend or damage the measuring tape.
• Ensure that the measuring tape does not become twisted inside the tank or while
the pipes are being laid out.
• Approximately half of the measuring tape is perforated with small holes at
20 mm (1 in) intervals. Install the measuring tape so that the perforated side is
wound by the gauge.
• Check to make sure that the measuring tape and the measuring wire do not come
off the sheave elbow roller during the process, and inspect them after they have
been installed.
• If the measuring tape must be passed through the 135 ° sheave elbow, ensure safety
before installing the measuring tape, as the footing is extremely dangerous.
• Inspect the joint between the float and the measuring tape once they are connected,
as it cannot be fixed once the tank is filled with liquid.
Installation procedure
1. Rotate the gate valve counterclockwise and open the gate valve completely, then
remove the sheave elbow cover and rear cover of the gauge.
Remove the gland of the gauge head rear cover with the included gland fixing
tool.
Remove the o-rings (2 rings).
2. Remove the tape guide and the lock screw.
3. Insert one end of the measuring tape (non-perforated side) into the tank from the
sheave elbow on top of the tank.
4. Pass the other end of the tape (perforated, looped side) through the sheave elbow on
the gauge's side and insert it into the gauge.
5. Pass the inserted measuring tape through the dust-proof slit, fix it to the tape drum
with a tape fixing thread, and coil it around the tape drum twice.
6. Loosen the installation threads (2 threads) and make adjustments so that the
measuring tape does not interfere with the dust-proof slit.
7. Pull the measuring tape inside the tank.
8. As for the length to the float, cut the measuring tape off, leaving approx.
1.5 mm (0.06 in).
9. Connect the measuring tape to the float.
For detailed connection instructions → 57.
10. Check to make sure that the measuring tape is not twisted.
11. Close the sheave elbow cover.
12. Tighten the gland by following the diagram below.
This completes the installation process.
