KPSI Level & Pressure Transducers: Application NotesEnhanced Accuracy of Ocean Level Data Available with Hydrostatic Submersible Transducers |

Ocean level monitoring has become increasingly important among scientific areas of study due to factors including global warming as well as seasonal changes that result in extensive flooding and damage. For physical oceanographers, ocean level data is imperative to their research and therefore, they are in search of the most accurate, quickest, cost-effective data acquisition equipment in the field. Over the years, water level monitoring equipment has evolved from a mechanical means of measurement involving buoys and manual data collection, where human error was a significant factor, to electronic techniques involving radar and acoustic sensors, as well as level transducers that automatically capture data and transmit it to a host PC.
When AmberJackSolutions, a company specializing in custom data acquisition and telemetry solutions, wanted to expand the capabilities of its B600 versatile tide gauge, the company looked at different aspects of the system’s water, atmospheric, wind speed, wind direction and solar radiation monitoring functions. AmberJackSolutions focused specifically on the B600’s water level sensors and compared the radar, acoustic and pressure technologies typically used to capture water level data in oceanic applications. The company found that the pressure sensor technology used in hydrostatic transducers not only provided data in a shorter amount of time, but the information was also more accurate, as compared to the other alternatives. Greater Accuracy with Pressure Systems
“The 735T provides greater accuracy, including much smoother curves, as compared to the results we received from other data collection instrumentation, giving us a more realistic picture of the actual sea levels being measured, “ said David Mendes, hardware engineer with AmberJackSolutions. The 735T features titanium construction, which enables the transducer to hold up exceptionally well under prolonged exposure to caustic environments, such as salt water. Each transducer also includes a SuperDry Vent Filter that utilizes a unique water block feature that self-seals in case the electrical cable is cut, as well as prevents moisture from entering the vent tube for at least one year. This double protection against moisture is crucial, considering the units are submerged in ocean waters. “The 735T requires underwater work to install the transducer, but the extra work is well worth the effort when the results of the level transducer are compared to radar and acoustic sensors. Our tide gauge systems collect data used to make informed decisions about sea levels and, in conjunction with seismic activity, to detect tsunamis. The installation costs are offset by the validity and timeliness of the information generated by the transducers and our customers’ subsequent ability to act on their data,” mentioned Mendes. Success with Hydrostatic Transducers With the use of Pressure System’s 735T level transducer, data can now be conveniently transmitted through GPRS protocol, saved on an SQL database in real time and downloaded for graphical viewing.

The success of the B600 is due in part to the superior 735T transducer, which provides accurate ocean level measurements in a timely manner.
