Water Column Profiling Build a cost-effective, vertical water quality profiling system for lakes and reservoirs.

Telemetry sensors are connected and suspended at user-defined The first step in building a water column profiling system distances along the string. Additional water quality is to decide how the data will be sent back to shore. Two measurement sensors, including single-parameter factors help determine the best telemetry method: sensors and multi-parameter sondes, can be connected site conditions and distance to a base computer. along the string using cable splitters. sensorBUS When the project computer can be located within includes three industry-standard, digital interfaces a few miles (line-of-site) or few hundred feet (1-wire temp string, RS-485 multi-drop and SDI-12) (non-line-of-site), license-free spread spectrum along with both 12 and 5 VDC power for connecting radio telemetry, such as the NexSens 4100-SDL additional water quality measurement sensors along Radio Data Logger and 4100-Base Radio, the water column. is the best choice.

The Ford Lake Dam was originally A NexSens T-Node water temperature string collects constructed by Henry Ford, who was an expert on data from these sondes, along with other T-Node hydroelectric power generation. The dam is currently temperature nodes, to obtain a complete vertical water owned and operated by Charter Township of Ypsilanti, quality profile. and it is still used for generating and selling electricity. University of Michigan researchers also chose to During late summer months, Ford Lake experiences integrate existing Turner Cyclops-7 and SCUFA massive algae growth, causing localized fish kills and submersible fluorometers into the system for measuring foul odor. As a result, the Lake has been the site of a chlorophyll, turbidity, and phycocyanin (blue-green research study sponsored by the US EPA (2003-2006) pigment). NexSens Technology created a connectorized and also by the USDA since 2006. The study, led by sensor cable with a UW Underwater Connector, making Professor John Lehman of the University of Michigan, integration to the buoy plug-and-play. probes the causes and possible corrective measures for the nuisance algal blooms that plague Ford Lake. Housed within each buoy, a NexSens 4100-SDL radio telemetry data logger in a submersible enclosure Researchers have developed a management plan that collects data from the instruments.

Why Rent? While it often makes sense to purchase outright, there are many short-term projects that simply make it cost-prohibitive. Here are some reasons why renting may be a better solution:

1 Renting products frees up cash flows that can be used for more vital capital expenditures, allowing customers to focus on their core functions.

2 Renting offsets the hidden costs included in purchasing and maintaining products. Storing spare parts and servicing equipment can drastically increase the total cost of ownership.

3 Owning physical assets when they are not being used greatly decreases the value. This fact can be remedied by renting equipment only when the project requires it.

4 Renting allows a company to stay contemporary with the rapidly changing technology. Fondriest’s promise to always carry cutting-edge instruments allows rental customers to remain cutting-edge as well.
