In order to ensure the normal use of compressor and compressor is determined the quality of work, in addition to measuring instrument for daily use, should be regularly inspected for the following instruments:

A, flow meter

Used to measure the gas flow rate.

Two, the standard pressure gauge

Used to check other pressure gauge.

Three, tachometer

Used to measure diesel engine, motor and compressor speed.

Four, stopwatch

As calculated by time for measurement.

Finally, according to the data about application of formula above instrument measureto operation could be seen from the compressor the quality of work, to take timelymeasures to deal with.
