METER Group

METER Group METER designs scientific instrumentation that delivers real-time, high-resolution environmental data. In 2016, two firms merged. Each was successful on its own.

Each had a unique focus. They were brought together by strong common values, similar roots, a history of collaboration, and shared expertise in science and engineering. The unified company combines the strengths of both firms to create powerful synergy, competitive advantage and new business opportunities. To know where you are going, you must know where you came from. Let’s take a moment to look

back. FROM PULLMAN TO MARS

Decagon Devices, Inc. was founded in 1983 by Dr. Gaylon Campbell, a renowned soil scientist and faculty member at Washington State University. The first Decagon product was an instrument to measure water in soil. Decagon quickly realized that other customers could benefit from their expertise in measuring water. New markets like food safety, pharmaceuticals and other industries needed solutions to determine water content and water potential in their products. Over the next 30 years, Decagon improved and expanded their expertise in engineering sensors, all while maintaining affordable product offerings. Today, Decagon products are used all over the world and even beyond: in universities, research and testing laboratories, government agencies, vineyards, farms and industrial applications – even on Mars. GERMAN SCIENTIFIC ENGINEERING

UMS AG was founded in 1989 by Georg von Unold, a mechanical engineer who was working at the renowned Helmholtz Research Center in Munich, Germany. The first UMS product was a scientific instrument for soil irrigation control. The tensiometer sensor series was quickly adopted by scientists due to its precision and reliability. To date, more than 20,000 UMS tensiometers have been used in research projects worldwide. In 1991, the product range was extended to cover environment monitoring systems – from proprietary sensor technology and the development of innovative components to planning and providing individual customized solutions. OUR DNA

8,367,180 meters. That’s precisely the distance from the doorstep of the headquarter in Pullman to the entrance of the headquarter in Munich. The businesses seem a world apart. But if you take a closer look, you will see that the people in these two places have always been much closer:

Both companies were founded by individuals who are passionate about measuring the natural environment. Both founders were initially driven by their own needs, but quickly saw that they could create products for their colleagues. Both companies share a drive to invent rather than follow. Both companies are committed to marketing through educating our clients. In Pullman as well as Munich, we speak the language of scientic engineering. In both places, the corporate culture is built around the importance of employees. We build a strong foundation on common ground, and our differences are complementary. Pullman has expertise in measuring the dry end, Munich the wet end. While Pullman excels in science and simplicity, Munich does so in engineering and precision. For over a decade, we’ve worked together in product development, supply and distribution, customer support and education. That was enough time to detect a clear fit and to decide to take the next step.

Even under normal conditions, high-energy power lines get hot.

That is why engineers designing underground transmission systems analyze the thermal properties of surrounding soil before breaking ground. Kai-Julian Hendler explains how thermal dryout curves help engineers understand the relationship between water content and thermal conductivity so buried power cables can dissipate heat through surrounding soils.

Soil water is only part of the irrigation picture.

Hear how Colin Campbell, President & CEO of METER Group, explains why irrigating an agronomic crop means understanding water available in the soil, atmospheric demand, and actual water loss from the crop.

The new ATMOS 51 VBR Actual ET Sensor takes measurements beyond reference ET by directly measuring actual evapotranspiration, helping teams better understand crop water use and plant stress signals.

Imagine trying to learn about weather without access to local weather data.

A teacher in western Kenya shares how a TAHMO weather station gives students access to near-real time, local measurements instead of relying only on examples from textbooks. Across Africa, many TAHMO stations are installed at schools, where the same weather data can support classroom learning, local farming and water decisions, scientific research, and government use as communities plan for a growing population.

Fine-tuning irrigation timing is much more effective with ET measurements, but traditional measurement methods are cost-prohibitive for many applications.

Dr. Carlos Wang discusses how variance Bowen ratio methods can help make field-scale evapotranspiration measurements more accessible when traditional eddy covariance systems are too complex or cost prohibitive for the application. The conversation connects ET data to water shortage challenges and the need for practical ways to measure water loss across more field conditions.

Good weather data starts with the station. Reliable long-term data starts with the maintenance plan.

Jeff Ritter and Chris Chambers explain why long-term weather monitoring starts with choosing a station that fits the expected lifespan, maintenance schedule, and field conditions. Cleaning funnels and solar panels, replacing drifting sensors, and budgeting for maintenance up front can help keep a station or network fit for purpose over time.

Good ET estimates start with knowing what each method can and cannot tell you.

Dr. Colin Campbell and Dr. Dirk Baker walk through ET fundamentals, common sources of error, and the tradeoffs between direct measurements, such as those taken by VBR or eddy covariance methods, and process-based approaches using atmospheric data to complete the Penman-Monteith equation.

Their discussion helps clarify what equipment is needed, where estimates can break down, and how ET can be used alongside soil and weather measurements to better understand water loss from managed and native systems.

Actual ET measurements can add field-scale context with an accuracy that reference ET alone cannot provide.

The ATMOS 51 VBR Actual ET Sensor directly measures water loss from plant and soil surfaces using the variance Bowen ratio technique. It is designed to help teams evaluate crop water use, irrigation strategies, and water movement in the field with plug-and-play compatibility for METER data loggers and ZENTRA Cloud.

When a project spans more than one field site, downloading data can become fieldwork of its own.

Katie explains how ZENTRA Cloud 2.0 helps clients access data from multiple logging devices without visiting each field site. For clients managing more than one site, that can mean less time spent downloading and maintaining equipment and more time working with the data itself.

Montana’s 2017 flash drought caused hundreds of millions of dollars in crop loss. A key missing signal was soil moisture.

Kevin Hyde of the Montana Mesonet explains how wind, temperature, and soil moisture data factored into a drought where several important conditions were missed. In the retrospective analysis, soil moisture measurement was identified as a crucial data need. Today, the Montana Mesonet uses soil moisture profiles alongside weather data to help monitor the soil reservoir across more than 100 stations.
