Accurate and reliable, these water level loggers feature a datalogger and pressure sensor for remote monitoring and recording of water level data. The water level logger’ s weather-resistant, cylindrical enclosure is compact enough to fit inside a 2" diameter pipe. Up to 24, 000 readings can be recorded, and the level logger is programmable in intervals ranging from one reading per second to one reading per day. Select from linear, logarithmic, and event-based recording. The silicon pressure sensor is barometric and temperature compensated and is fully encapsulated so that “ O� rings and underwater connectors will not fail. Also included is Global Water Software, a Windows® -based software which allows for easy access to stored data and makes setting options easy. Downloaded data can be opened in a spreadsheet program for analysis and graphic presentation. Recording rate: linear fixed intervals from 1 per second to every 32, 000 seconds ( also 0 to 32, 000 minutes, hours, and days) ; logarithmic test ( for pump and slug test) ; event-based ( value set by user) . Resolution: 12-bit. Accuracy: 0.1% of full scale at constant temperature; 0.2% over temperature range. Range: 25' Model, 0 to 15' ; 50' Model, 0 to 30' . Computer interface: RS232, cable provided. Power: internal 9V DC battery, powers logger and sensor for up to three years. Dimensions: Pressure transducer: .812" diameter x 7" L; Data logger enclosure: 1.875" diameter x 12" L.
