本报告评估了两种检测地上储罐泄漏的体积方法——精密温度传感器和质量测量方法。在直径为117英尺的炼油厂储罐上进行了一组受控实验，以检查差压对常规液位和温度测量系统的影响。还探讨了高性能所需的泄漏检测试验的特点。另见配套文件Publ 322。

Two volumetric approaches to detecting leaks from aboveground storage tanks--precision temperature sensors and mass measurement approaches--are evaluated in this report. A set of controlled experiments on a 117-ft. diameter refinery tank is used to examine the effects of differential pressure on conventional level and temperature measurement systems. The features of a leak detection test needed for high performance are also explored. See also companion document Publ 322.
