美国水文仪器中心(H1F)新研制的R200压力式水位数据记录器是一种电池供电、微处理机控制的低成本记录器,主要用于测量观察井(最小口径为两英寸)内的水位,并可记录日平均水位,数据容量可长达一年。一、仪器研制目的美国地质调查局是负责提供水资源资料的主要机构,它需要各种监测和收集水位数据的水文仪器。监测数千个地下水观察井的水位是它的任务之一。研制R200的目的是为了改善目前地下水的监测状况。目前,绝大多数地下水观察站点是通过
The newly developed R200 pressured water level data logger from the American Hydrological Center (H1F) is a battery-powered, microprocessor-controlled, low-cost logger designed to measure the water level within the observation well (two inches minimum) And record the average daily water level, data capacity up to one year. I. Purpose of Instrument Development The United States Geological Survey is the main body responsible for providing information on water resources and needs a variety of hydrological instruments to monitor and collect water level data. Monitoring the water level of thousands of groundwater observation wells is one of its tasks. R200 was developed to improve the current state of groundwater monitoring. At present, most of the groundwater observation sites are passed
