The Seametrics PT2X is ideal for observing flow patterns, testing pumps, and monitoring groundwater, well, tank and tidal levels. A pressure and temperature sensor with integrated data logging, this sensor is constructed with 316 stainless steel, fluoropolymer, PTFE—providing highly accurate readings in rugged and corrosive field conditions.

Sensor:

  • Measures pressure, temperature, and time
  • Available in absolute, gauge, or sealed gauge
  • Thermally compensated—great where water temperatures vary, such as in streams or industrial tank applications
  • ± 0.05% FSO typical accuracy
  • Low power—2 internal AA batteries
  • External power options (12 VDC) with AA’s acting as backup
  • 316 stainless steel, fluoropolymer, and PTFE construction (titanium optional)
  • Available for both Modbus and SDI-12 protocols

Data Logger:

  • Non-volatile memory—your data will not be lost in the event of a power failure
  • Flexible, multi-phase logging sequences—measure at your specified intervals and save instructions to disk for reuse
  • Pause logging feature—temporarily pause the logging while repositioning or transporting sensor
  • Delayed start feature—state a specific future start time, making it easy to set several sensors to start at the same time

Cabling & Networking:

  • Wireless connectivity
  • RS485 network—allows several sensors to be networked together and provides much longer cable leads
  • Field-serviceable connectors—easily remove the connector, route cable through well seals, walls, or conduit, and then replace connector
  • Available cableless or with a variety of cable options, including polyethylene, polyurethane, and FEP

Software:

  • Comes with free Aqua4Plus control software to get up and running immediately
  • View your data in real-time
  • Easy export to spreadsheets and databases
  • Barometric compensation utility for use with absolute sensors
  • Update sensor via firmware while in the field—great for future updates or custom development

Charles River Algal Blooms Stop Swimming and Launch a Floating Wetland

The Charles River used to be a swimming hotspot for Cambridge and Boston residents. Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river. An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.

Harnessing the Gulf Stream for Renewable Energy

The Gulf Stream, the massive western boundary current off the east coast of North America, moves water from the Gulf of Mexico north and west across the Atlantic Ocean. There’s a lot of energy in that much moving water and researchers are trying to put it to use. Although the Gulf Stream’s path shifts (researchers say it acts like a wiggling garden hose), in a couple of spots, it stays relatively stable. At one such spot off the coast of Cape Hatteras, North Carolina, researchers have dropped moorings and research instruments to study the current with the eventual goal of harnessing it for renewable energy.

Buoys in the time of Covid: Delays to important information

In early 2020, Michigan found itself facing one of the worst outbreaks of Covid-19 in the country. Though it’s close to second nature now, businesses, schools and governments were suddenly forced to conduct business without close contact. Universities and research institutions had to pause some scientific research. Whatever was able to continue slowed to a crawl. Around the Great Lakes, a network of buoys monitors dozens of water quality parameters and lake conditions, reporting them in real time. This year, the monitoring season was cut a bit short as Covid-19 restrictions hit in the weeks before buoys were set to be deployed.
