Overview
The KISTERS TBL-70 dual tipping bucket flow gauge is used for measuring water seepage coming out of a pipe or a drain. The unit is equipped with two distinct buckets to provide best accuracy over a large range of flows: a smaller bucket at the top of the gauge to measure at low flows and a larger one at the bottom to measure at high flows. Each bucket is connected to its own dual reed switch effectively enabling redundant data acquisition in two distinct data loggers, or providing data to two devices (e.g. a data logger and a counting display), etc.

Operation
The two buckets operate simultaneously up to 6L per minute. At low flows where the large bucket is not full to tip, more accurate results can be obtained from the small bucket’s reed switch output. At higher flows above 6L per minute, the smaller bucket at the top has to be removed by the user. Data is then generated solely by the larger bucket’s reed switch output.

Material PVC plastic and stainless steel
Resolutions
  • Metal bucket, top of gauge: 70 ml, up to 6 L/minute
  • PVC bucket, bottom of gauge: 0.5 L or 1.0 L (selectable), up to 25 L/minute

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.
