Foreword

GB/T 37770 "General Requirements for Automatic Leveling of Frozen Light Hydrocarbon Fluids" is divided into three parts. --- Part 1. Automatic level gauge for liquefied gas transport vessels; --- Part 2. Automatic level gauge for onshore frozen storage tanks; --- Part 3. Automatic level gauges for liquefied petroleum gas and chemical gas marine carriers and floating roof tanks. This part is the second part of GB/T 37770. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This section uses the redrafting method to modify the general requirements for the use of ISO 18132-2.2008 "Fast Light Hydrocarbon Fluid Automatic Level Gauge" Part 2. Automatic Level Gauge for Onshore Frozen Storage Tanks. Compared with ISO 18132-2.2008, this part of the structure changes. delete ISO 18132-2.2008 Chapter 5, will be related to OIMLR85 The content is moved into the 4.1 General Rules. The main technical differences and their causes in this section compared with ISO 18132-2.2008 are as follows. --- Increase the reference to GB/T 3836.6, GB/T 3836.7, GB 3836.14 to adapt to the technical conditions of China.

1 Scope

This part of GB/T 37770 specifies the general performance, installation, testing and calibration of an automatic level gauge for onshore frozen storage tanks. Claim. This section applies to automatic liquid level measurement of frozen light hydrocarbon fluids such as liquefied natural gas and liquefied petroleum gas storage tanks without pressure and near atmospheric pressure. system. This section does not apply to automatic level gauges for pressurized storage tanks.
