1 Scope This seclion describes how 10 correctly use various Iypes 01 liquid-in-glass Ihermomelers 10 accuralely delermine Ihe lemperalures 01 hydrocarbon liquids. Olher melhods , equipmenl , and procedures lor lemperalure delerrninalion are described in Ihe olher sub-seclions 01 API MPMS Chapler 7 This chapler describes Ihe melhods , equipmenl , and procedures lor manually delerrnining Ihe lemperalure 01 liquid pelroleum and pelroleum producls wilh liquid-in-glass Iherrnomelers. This chapler discusses lemperalure measuremenl requiremenls in general lor cuslody Iransler , invenlory conlrol , and marine measuremen ls . The aclual melhod and equipmenl selecled lo r lemperalure de lerminalion are left 10 Ihe agreemenl 01 Ihe parties involved. The manual melhod covers: Non-pressurized lanks and non-pressurized marine vessels Gas-blankeled lanks and gas-blankeled ma rine vessels II does nol cover under pressures in excess 01 21 kPa gauge (3 psi gauge) or cryogenic lemperalure measuremenl , unless equipped wilh a Ihermowell T he requiremenls 01 Ihis chapler are based on praclices lor crude oils and pelroleum producls covered by API MPMS Chapler 11 .1 (ASTM D1 250).

A thermometer has two important componen ts : a te mperature se n so r in which some physical change occurs t ha t is dependent on temperature , and some means of indicating and/or transmitting this physical change as a value. 3.3 .1 liquid-in-glass thermometer (Ll GT) A glass thermometer co ntaining mercury or a low-hazard liquid th at indicates th e temperature being measured. 3.3 .2 low-hazard liquid A liquid that is biodegradable , non-hazardous and considered non-toxic in quantities specified fo r the thermometer specificat io n. 3.3 .3 mercury-in -g lass thermometer (MIGT) A glass thermometer containi ng mercury that indicates the temperature be i ng measur ed 3.3 .4 thermometer A liquid-in-glass t he rmometer designed to ind icate temperatures correc tl y when the bu lb and a speci fi ed pa rt of the stem are exposed to the medium bei ng measur ed . 3.3 .5 total-immersion thermometer A l iqu id-in-glass thermometer designed to indicate tempera tu res correctly when just that of the thermometer containing the liq ui d is exposed to t he medium being measured 4 General Precautions 4.1 Safety Safety sha ll be cons id ered for the specificat ion , installat ion and operati on of all equipmen t. Refer to API RP 500 and NF PA 70 for guidan ce. When loading li qu ids that ca n accumulate static charges , refer to the precautions desc ri bed in the International Safety Guide for Oil Tankers and of Li fe at Sea, AP I MPMS Chapter 3 , and A PI RP 2003. Care must be taken with thermometers to prevent breakage , wh i ch will result in a safety hazard. If the li q uid in t he thermometer is mercury , must be taken.4.1 .1 MercuryWarning WARNING: Mercury has been designated by the Environmental Protection Agency (EPA) and many state agencies as a hazardous material that can cause central nervous system, kidney and liver damage. Mercury or its vapor , may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Oata Sheet (SOS) or Material Safety Oata Sheet (MSOS) for details, and the EPA website http: //www .epa.gov/mercury/faq. htm for additional information. Users should be aware that selling mercury or products containing mercury , or both , in your state may be prohibited by state law
