User's Guide for 8200 Bubbler Gauge (Installation and Operation) Updated February 1998

摘要

The Sutron 8200 digital bubbler water level gauge was developed to provide a replacement system for the traditional analog chart-recording gauges. The gauges provide: Improved fittings, to assure more reliable and leak-free connections, allowing more operational life for the nitrogen cylinder$ Completely electronic measurement and recording of pressure corresponding to the water level, to eliminate reliability problems caused by the chart drive, pen, and ink supply of the analog gauge$ Retrieval of station data electronically. At present, there are three methods to retrieve data from the measurement system: (1) by connecting a lap-top computer directly to the gauge, (2) by remotely receiving the data via line-of-sight radio communications, or (3) by GOES$ and Direct entry of digital field data using diskettes into Oceanographic Products and Services Division, eliminating the manual digitization of analog chart records. The development of the digitized bubbler gauge is due to culmination of cooperative efforts from Oceanographic Products and Services Division (OPSD) at Silver Spring, MD, field activities of the Coast Survey's Hydrographic Surveys Branch, and the Pacific Regional Office (PRO) of the Field Operations Branch (FOB) at Seattle, WA. Close interaction between all parties involved has resulted in measurement system modifications while taking into account suggestions and comments from the field user and maintaining the measurement performance and system compatibility required for data analysis. General procedures on system installation and operation are summarized in this document. Each gauge enclosure contains a page of brief operating instructions summarized from this manual, setup parameters for the Sutron 8200 data collection platform, and a log sheet for recording field visits, operational problems, and/or services (e.g., battery replacement, etc.).
