Flow meters in these areas must be capable of measuring a wide range of materials.

Water Cooling

Monitoring process cooling systems, including industrial cooling circuits and HVAC systems, helps maintain your plant or building efficiency, conserve energy, and improve the bottom line. Constant monitoring and control of these systems can easily be done using flow monitoring and control instrumentation from AW-Lake.

General Industrial

General industrial plants around the world have been using AW-Lake flow meters to maintain their process operations, plus they have integrated our meters as a vital part of their end product. Our broad portfolio of flow measurement equipment provides solutions to your paint operations.

Test Systems

With increasing product complexity, tighter regulations, and growing demands on companies to reduce operating costs and improve product quality, there is more focus on test and measurement procedures and equipment.

Alternative Energy

As the world shifts towards sustainable practices, the demand for efficient energy production methods intensifies. AW-Lake flow meters are used in many ways within renewable energy sectors such as solar, wind, hydro, and biofuels.

Marine

In a field where fuel consumption attributes to most of the total operating costs, it is critical for marine ship owners and operators to monitor their fuel systems. Accurate fuel consumption is key to understanding how and where to find areas to improve efficiency and control costs.

Chemical

AW-Lake understands the challenges and intricacies of chemical / petrochemical process monitoring with flow meters. We have the depth of experience with corrosive, aggressive liquids and gases that you need in your flow measurement partner.

Environmental

As the the world continues to examine ways to lesson our impact on the environment and develop new technologies to support those efforts, flow measurement enters the conversation more and more.

Aerospace

AW-Lake flow meters are trusted in the aerospace and aviation industry, where they ensure precise measurement and control of fuel, hydraulic fluids, and other critical liquids and gases. They play a vital role in maintaining optimal performance, ensuring safety, and enhancing fuel efficiency.
