【Abstract】 In the petrochemical industry， liquid level measurement plays a pivotal role. In the temperature compensation based tank level monitoring system， the magnetostrictive level sensor can detect the required data. This data is transmitted to the data center under the influence of the GPRS communication module together with the data detected by the temperature sensor. The data center applies a temperature compensation algorithm to process the data. This measurement method can accurately measure the oil and gas level， the oil and water level， and the temperature inside the storage tank to measure the crude oil production. The system finds that the measurement method is safe and reliable through the field test and application of the oil storage tank， which can directly reflect the liquid level of the oil storage tank， and can monitor the change of the liquid level in the oil storage tank in real time. In addition， the measurement error can be corrected in real time， with good generalization and practicality. It is a new t...
