The Geosub Controller is designed specifically for use with Geotech's Geosub 2 Stainless Steel Pump. It provides a safe conditioned variable DC output power from an AC power source. Built-in sensing gives the operator accurate and precise control over the pump during sampling events.

An average 1000 Watt gasoline powered generator with 1 gallon of gasoline will operate the Geosub Controller and Geotech's sampling pump at full power for 18 hours continuously. Generally much longer run times can be expected as the controller is used to reduce water flow for low flow sampling.

An easy-to-use programmable user interface with bright display offers precise control over flow rates during groundwater sampling events. Site specific settings and conditions can easily be stored and recalled for more efficient repeatable sampling events. Rugged construction and easy to connect cables make setup and portability a breeze. In addition, the controller includes a user-set dry run protection feature.

  • Converts AC Voltage to variable up to 300 watt DC voltage output
  • Short circuit protection for your safety
  • Heavy duty rated power cable for years of service
  • 2-line x 16-character wide temperature range alpha-numeric digital display
  • Push button Up/Down control
  • Internal processor saves individual well parameters
  • Optional DC to AC Inverter can be connected to a vehicle battery
Questions & Answers
Does the controller need to be grounded?
Yes, the controller must be wired to a negative ground system. If using a generator larger than 2000 Watts, a grounding rod driven into moist earth must be installed and electrically connected.
What kind of power source is this compatible with?
The SS Geosub controller can be connected to any AC power source, such as an AC gasoline powered generator. A DC to AC inverter is available under the Accessories tab to connect the controller to a DC source such as a car battery.
Is the controller field serviceable?
No, The SS Geosub controller has no field serviceable components and should never be opened by an unqualified person.

Building Reliable Systems: Hydroelectric Dam Monitoring in Western Pennsylvania

Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.

Sustainable Data Collection: Climate Monitoring in the Caribbean

Environmental monitoring in the Caribbean may be essential, but it has also historically been placed on the back burner. Albert Jones, Instrumentation Officer for the Caribbean Community Climate Change Centre (CCCCC), explains, “Data collection itself is not what is considered one of those sexy activities where you can easily get funding.” Still, monitoring the water surrounding island nations is necessary to protect residents and the environment. The CCCCC works to establish environmental monitoring networks and systems in the Caribbean. One aspect of Jones’ work centers around data buoy instrumentation and deployment,—equipment that will be used to support Ecoforecasts for Coral Health Monitoring and to provide valuable environmental data to the public.
