Solinst Levelogger 5 Water Level Loggers

Multiparameter Testing
The Solinst Levelogger 5 combines a pressure sensor, temperature detector, 10-year lithium battery, and datalogger, sealed within a 22mm x 160mm (7/8" x 6.3") stainless steel housing with a PFAS-Free corrosion-resistant coating baked-on using polymerization technology.

Hastelloy Pressure Sensor
The Levelogger 5 measures absolute pressure using a Hastelloy pressure sensor and offers high resolution and an accuracy of 0.05% FS. Readings are stable in extreme pressure and temperature conditions. The Hastelloy sensor can withstand 2 times over-pressure without permanent damage. Combined with the durable coating inside and out, the Levelogger 5 has high corrosion and abrasion resistance in harsh environments.

Protective Design
The logger uses a Faraday cage design, which protects against power surges or electrical spikes caused by lightning. Its durable maintenance-free design, high accuracy and stability, make the Levelogger 5 the most reliable instrument for long-term, continuous water level recording.

Questions & Answers
What is the warranty period for the Levelogger?
Most standard products from Solinst carry a 3-year warranty, stating that items should be free of workmanship and material defects. There are some additional conditions that are outlined in Solinst' warranty statement found here: https://solinst.com/about/warranty.php 
Can the Levelogger be used in saltwater environments?
Yes. Leveloggers have a corrosion-resistant coating. In harsher environments Solinst recommends taking additional steps to protect the logger. More information can be found in the user guide, page 76. 
Can the Levelogger be connected to an external data logger?
Yes, the Levelogger can be integrated with an external data logger via SDI-12 output through the use of a direct read cable and SDI-12 interface cable (PN# 115133). Please see the Accessories tab for pricing on these options.
What is the difference between the Solinst 5m range Levelogger 5 loggers and the 10m, 20m, 30m, 100m and 200m loggers?
The Solinst Levelogger 5 range correlates to the maximum depth the sensor can be deployed at while still maintaining accuracy and preventing damage to the internal sensor.
How is data downloaded from deployed Leveloggers in the field?
Deployed datalogger data can be downloaded directly to a computer with the field reader, to a transportable USB unit with the DataGrabber 5, directly to a smart device with the App Interface, or to the internal logger on the Solinst Readout Unit (SRU).
What are the deployment options for the Levelogger 5?
The Levelogger 5 can be deployed using a stainless steel cable, Kevlar rope, or other secure material. Leveloggers can also be deployed using direct read cables, allowing data download without pulling the logger from the well.
Do Leveloggers contain PFAS?
No. Solinst Leveloggers are manufactured with materials known to be PFAS-free.
How often does the Levelogger need to be calibrated, and does that need to be done at the factory?
Leveloggers are factory-calibrated before they ship and will not need re-calibrated unless overpressurized or damaged in the field. A re-calibration is performed at the factory.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute

Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.

Wave Sensors Integration with NexSens Buoys: A Cutting-Edge Solution for Wave Measurment

Real-time wave data supports accurate weather prediction, safe and efficient maritime operations, and provides valuable safety and operating condition information for recreation and commercial fishing. Understanding wave dynamics also helps with the design of protective coastal structures like seawalls, breakwaters, and jetties. It also supports better prediction of their impact on sediment transport and coastal geomorphology. Wave data is a key factor in qualifying and designing offshore wind farms and harnessing kinetic energy for electrical generation. It helps with the understanding of ocean-atmosphere interactions and contributes to studies of sea-level rise and climate change impacts.
