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.

Resolutions
  • Metal bucket, top of gauge: 70 ml, up to 6 L/minute

Three Decades of Research at Acton Lake

A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.

Source Water Monitoring in Albany, New York: Tracing Water Quality throughout Tributaries

Thousands of US cities pull their drinking water from natural source waters like reservoirs, rivers, and streams, making overall watershed health a key consideration for water providers. In Albany, New York, the Albany Department of Water and Water Supply delivers drinking water to over 100,000 residents as well as monitors and manages the larger drinking water supply watershed. Hannah Doherty, Environmental Specialist at the Albany Department of Water and Water Supply , spends her days working with a small team to monitor the drinking supply and the connected water bodies. Doherty explains, “We’re the first to encounter the water that ends up being the drinking water.

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.
