Level Transducer Monitors Water In Harsh Remote Environments

Measurement Specialties’ TruBlue 255 Level data logger remotely monitors water levels in the harshest water environments. The Lithium-ion battery-powered unit can collect up to a half-million time stamped pressure and temperature data points with its standard 8 MB of internal memory or can be outfitted with 56 MB to gather 3.7 million data points. Constructed of welded 316 stainless steel or titanium, the fully-sealed level transducer withstands the harsh agents found in fresh and salt water applications including aquifer characterization and groundwater monitoring. The data logger also provides accurate measurement in flood and storm management, tide and harbor gauging, and rapid sampling wave studies. The unit can sample and log data at 4 Hz for 14 days using the auxiliary battery pack and extended memory options. Equipped with a low power MCU, the transducer can log depth and temperature for up to ten years. Level accuracy is ±0.05% FS TEB from 0°C to 50°C with less than 1 cm of vertical accuracy error on up to 10 m of water. High speed data retrieval of 1,500 points/sec is facilitated via the TruWare software for PC or mobile devices. Pricing for a TruBlue 255 Level transducer starts at $395 each.
