Webb21 feb. 2013 · The auditors claim without lagging, the temperature measured in a thermowell may not be the same as the gas temperature. A temperature difference of 0.5degC will impact on volume measurement by as much as 0.3 per cent. For fiscal/custody transfer metering systems, the temperature is always measured … WebbStraight shank thermowells are designed for use with instruments that have wide stem diameters or short stem lengths. Lagging Extension Lagging extension thermowells are used on applications where insulation covers the vessel or piping system. The extension length (T-length) is the measurement between the instrument connection and process ...
