| The length of fuel assemblies and fuel rods is measured by comparison with the length standard by means of cathetometer. |
|
| The difference of the two readings on the cathetometer would give the corresponding length measured on the glass column for 100 ml. |
|
| The vertical drops can be determined with a cathetometer even when someone else is gathering data with the apparatus. |
|
| Both a change in the sample weight caused by adsorption and differences in a U-tube mercury manometer level were measured by a KM-6 cathetometer. |
