Dwyer Instruments have released the LDL2-030 vented water level data logger. The LDL2-030 vented water level data logger has a vented cable and an end cap to allow it to automatically compensate for atmospheric pressure fluctuations. It measures water level up to 9.14m (30 ft) and has an internal temperature sensor that accurately records temperatures between -40 and 80°C (-40 to 176°F). Its design makes it suitable for use in waste water treatment facilities as well as monitoring well and ground water levels.
The battery-powered LDL2-030 vented water level data logger can store over 16,000 measurements per channel, and the software allows for user selectable sampling rates. The easy to use DL700 software allows it to be easily started and stopped from a PC or delayed to start up to six months in advance.
