In frame 6B, 30 MW machine vacuum gauge/manometer is used for monitoring vacuum of main lube oil tank of gas turbine. This meter is currently mounted on the accessory compartment wall outside the compartment. But it is located little far from mist eliminator and is not visible while standing in front of mist eliminator and maintaining vacuum. Currently length of tubing from MOT to vacuum gauge is about 2-3 meters.
I asked instrument engineer to relocate the gauge nearer to the Mist eliminator by extending its tubing from MOT. But he said that it is not feasible because it will be a more distance for proper measurement of vacuum through manometer and vacuum will not be measured correctly.
Is it correct?
if it is correct then what is permissible distance?
and is there any other solution to this?
