使用上述新设备，华盛顿州塔科马市的劳动时间减少了65%。新重力分析罐的排水速度比旧罐快80%，仅需2 1/2分钟即可排空全部250立方英尺。计算机实际上是自己运行测试的:设置适当的流速、水量和操作控制阀。留给操作员的唯一任务是设置仪表的寄存器、开始测试和输入仪表读数。剩下的都是电脑！只需输入仪表号，即可在几秒钟内检索到测试数据。有了20MB的硬盘，可以存储大约18000条米记录。利用内部劳动力和设计服务为该项目节省了大量成本，总计6万美元。 00.

A 65% reduction in labor time was realized at Tacoma City, (Washington) using new equipment described. The drain on the new gravimetric tank drains 80% faster than the old tank, emptying the entire 250 cubic feet in just 2 1/2 minutes. The computer actually runs the tests by itself: setting the appropriate flow rates, water quantities, and operating the control valves. The only tasks left to the operator are setting the meter's registers, starting the tests, and entering the meter reads. The computer does all the rest! Test data can be retrieved in seconds by merely typing in the meter number. With the 20 MB hard drive, there is room for approximately 18,000 meter records to be stored. The utilization of in house labor and design services accounted for a significant savings in the cost of the project, which totaled $60,000.00.
