Operating much like a turbine flow meter, the paddle wheel flow meter consists of a freely rotating wheel which is outfitted with magnets on the blades or “paddles” of the wheel.

Helical Flow Meters

Helical gear ("screw-type") flow meters are designed for measuring highly viscous, abrasive, and filled fluids including lubricating and non-lubricating media, such as polyurethane, polymers, greases and oils.

Turbine Flow Meters

Axial turbine flow meters are designed with wear resistant internal components to provide trouble-free operation and a long service life in a wide variety of industrial applications.

Ultrasonic Flow Meters

Non-contact ultrasonic flow meters for accurate, instantaneous mass & volumetric flow rate measurement of clean, non-aerated fluids in full pipes such as water, chemicals, and oils.

Flow Electronics

Electronics coupled with our mechanical flow meters deliver flow data in your preferred format, whether a local display, remote transmitter, or simple pickup.

Fluid Power / Hydraulics

Flow meters used to monitor flow readings in fluid power systems are essential to properly monitoring your process, diagnosing system errors, and ensuring system performance. Our expertise in this area goes back decades with numerous flow meters for the hydraulics and fluid power system industry.

Oil & Gas

From corrosive subsea environments, offshore production platforms, onshore oil fields, or refineries we have the flow expertise to tackle these tough jobs. Difficult oil and gas flow metering challenges like high pressures, pulsating flows, corrosive media and harsh environments are our daily business.

Heavy Industrial

For challenging industrial environments like mining, steel & paper mills, and industrial vehicles we offer flow meters with easy flow paths to run thick materials, rugged meter bodies that handle extreme conditions and designs with high shock and vibration resistance.

Paints/Sealants/Adhesives

Automotive plants and their Tier-1 suppliers have been using AW-Lake flow meters for 40+ years to monitor usage of paints, coatings, adhesives, lubricants, and other fluids to maintain strict process control and manage operational costs. 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.

Real-World Applications


Offshore Chemical Injection

The HUB-40EX Transmitter is a great choice for offshore chemical injection skids when no local display is needed. These units are built to withstand harsh environments, including extreme temperatures, high humidity, and saltwater exposure. They are certified for hazardous areas and are made of corrosion resistant materials. Their smaller footprint are also an advantage on crowded skids.

Hydraulic Test Stands

Fracking operations require chemical injection systems to monitor and inject chemicals such as corrosion inhibitors, biocides, and H2S inhibitors into fracking fluid to ensure flow assurance and reduce well contamination. These systems, often mounted on movable trailers, must operate effectively in various environmental conditions, including extreme temperatures.

 

 

Industrial Paint Booths

In paint operations, the need for Ex certified electronics is critical due to the presence of flammable solvents and volatile organic compounds (VOCs). These substances create a hazardous environment where even a small spark could lead to an explosion or fire. The Ex-certified HUB-40EX Transmitter is specifically designed and tested to prevent ignition in such volatile conditions, ensuring the safety of the workplace and compliance with stringent industry regulations.
