Water level data logger offers more memory

It is part of the company’s TruBlue line specifically designed for long-term measurement of water levels in environmental and watershed management applications including groundwater, surface water, wave height, tide and harbour gauging.

The TruBlue 255 has a standard internal memory of 8 MB and can storw up to 550,000 level and temperature measurements. An additional 56 MB memory increases storage capacity to 3.7 million measurements. Its internal 3.6 V lithium battery, with on-board surge protection, has a lifespan of ten years based on one reading every five minutes, making the transducer suitable for remote environmental data collection and process monitoring. An auxiliary battery option doubles the battery lifespan and makes it suitable for rapid sampling applications such as wave height studies.

Sampling modes include linear, linear averaging, and event, with programmable sampling rates of up to 8 Hz. This new unit provides an accuracy of +0. 05% FS total error band which includes changes in temperature within the compensated temperature range of 0°C to 50°C.

Data graphing

The data logger is shipped with TruWare, software created specifically for the line. Users are able to graph and export logged data.

The TruBlue 255 Level data logger is available in full scale water level ranges from 0-16 M H2O up to 0-188 M H2O (from 22 to 300 psi). The ¾ inch diameter unit comes in welded 316 SS or titanium, making it suitable for a variety of applications including brackish and seawater.
