(3) Precautions When Handling Capillary Tubes
• When handling capillary tubes, be careful not to twist them.
• When unwinding a capillary tube, hold the flange portion and turn the tube such that it reverts
to a big loop.
• Attach the capillary tube in such a way that it extends downward as much as possible.
• Do not turn the tube in such a way that it becomes twisted near the base.
• Secure the middle of the capillary tube to prevent vibration.
(4) Precautions When Attaching the Flange During Sealed Tank Level
Measurement by a JTE Model Transmitter
• The setting range when attaching a transmitter high pressure (HP) flange to the upper
portion ofthe tank is different from that when attaching one to the lower portion of the tank.
(Seesection 3-10-2.)
• When attaching a transmitter high pressure (HP) flange to the lower portion of the tank,
put a minus sign on the height value when setting the sealed liquid compensation function.
(Seesection 3-10-2.)
• For the JTE930S model, be sure to attach the transmitter high pressure (HP) side to the upper
portion of the tank.
