METHOD AND SYSTEM OF UREA SOLUTION LEVEL MEASUREMENT ADJUSTMENT DISPLAY AND HEATER OPERATION

According to an embodiment of the present invention, a method and apparatus for correcting and displaying a measurement value of a urea solution level and operating a heater includes: measuring the concentration of a urea solution injected into a urea solution tank through a urea solution quality sensor; determining whether a negative urea solution has been injected into the urea solution tank through the measured urea water concentration; correcting the urea solution level measurement value in accordance with the urea solution concentration if it is determined that the negative urea solutionhas been injected into the urea solution tank; comparing the urea solution level measurement value to a reference urea solution level measurement value; and turning on a warning light if the urea solution level measurement value is lower than the reference urea solution level measurement value. 本发明涉及种调节和显示尿素溶液液位测量值以及使加热器运转的方法和系统，该调节和显示尿素溶液液位测量值的方法可以包括：利用尿素溶液品质传感器，测量注入到尿素溶液箱中的尿素溶液浓度；利用测量的尿素溶液浓度，确定不纯的尿素溶液是否注入到尿素溶液箱中；当不纯的尿素溶
