Petroleum and liquid petroleum products. Measurement of level and temperature in storage tanks by automatic methods - Measurement of level in pressurized storage tanks (non-refrigerated) Ingestion-build-51215 together with the test methods1 Scope This part of ISO 4266 gives guidance on the accuracy, installation, commissioning, calibration and verification of automatic level gauges (ALGs) both intrusive and non intrusive, for measuring the level of petroleum and petroleum products having a vapour pressure less than 4 MPa, stored in pressurized storage tanks. This part of ISO 4266 gives guidance on the use of ALGs in custody transfer application. This part of ISO 4266 is not applicable
