| объём продукта, измеряемый при его собственной температуре | volume (The volume measured at product (measured) temperature Метран) |
| объём продукта, измеряемый при исходной температуре | volume (The volume of a product at a (standard) reference temperature. The volume measured is corrected back to a reference temperature, typically 60ш F (15ш C) per API standard Метран) |
| температура при установке | installation temperature (The temperature of a tank at the time the sensor mounting measurements are taken. The HIU compensates for any changes in sensor mounting due to the thermal expansion of the tank based on the expansion coefficient of the tank material. For an insulated tank the installation temperature equals the product temperature. For an uninsulated tank the installation temperature equals the air temperature plus the product temperature, divided by two Метран) |
