A method for monitoring an oil level of an oil-lubricated compressor, the method including: reading at least one oil level sensor, by which an oil level representing the compressor oil level is detected; checking compliance with at least one predetermined verification criterion for verification of the read-out oil level; and relaying an oil level signal if the read-out oil level complies with at least one relaying criterion according to whether the oil level reaches or falls below a predetermined oil level and with the at least one verification criterion.
