A method for measurement of wax thickness in a pipe or processing equipment through which hydrocarbon flow passes, the method including the following steps: the first measurement of temperature upstream and downstream of the pipe section, application of a short thermal pulse that does not release deposits to the pipe section, the second measurement of temperature upstream and downstream of the pipe section, and calculation of deposits thickness from the change of temperature difference between the first and second temperature measurements. The device for wax thickness measurements in a pipe or processing equipment through which hydrocarbon flow passes, comprises temperature sensors for the first temperature measurement upstream and downstream of the pipe section, a heater for application of a short thermal pulse that does not release deposits to the pipe section, the temperature transmitters being suitable also for the second temperature measurement upstream and downstream of the pipe section after application of the short thermal pulse, and a computer for calculating the deposits thickness from the change of temperature difference between the first and the second measurements. |
