Gear Meters

Gear meters specifically spur gear, are ideal for low flow rates, viscous fluids, and measurement of flows involving starts and stops or pulsing.

Variable Area Meters

Variable Area flow meters are a type of rotameter that measure oils, liquids or gases by relating linear displacement of an internal “float” or sharp-edged orifice plate to a corresponding flow rate.

Coriolis Mass Flow Meters

TRICOR Coriolis flow meters are highly accurate and repeatable multi-variable instruments that measure mass flow, density, and temperature with calculated volumetric flow and feature a very easy user interface.

Paddle Wheel Flow Meter

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.

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.

Flow Rate Alarm

Flow Rate Alarm ensures sufficient flows of coolants and lubricants in mobile hydraulic equipment and industrial process control. Field adjustable alarm setting available in single or duel switch.

The Flow Rate Alarm ensures sufficient flows of coolants and lubricants in mobile hydraulic equipment and industrial process control. This variable area flow meter comes equipped with simple on/off logic and a field adjustable alarm setting for simplicity of use. The rugged cast aluminum NEMA type 4X enclosure allows for weather-tight construction in outdoor environments where liquid tight seals are required. Take advantage of the economical protection with the Flow Rate Alarm. It sends alerts of incorrect pneumatic, lubrication or cooling volumes, which protects expensive equipment and reduces production downtime.

 

Field Adjustable Alarm Setting: Only an allen wrench is required to change the flow alarm setting.

Weather-Tight Construction: Rugged cast aluminum NEMA type 4X enclosure allows installation outdoors and in environments where liquid tight seals are required.

Simple On/Off Logic Positive: alarm points using dry-contact, SPDT switches, reduce the complexity found in standard rotameter OFF/ON/OFF circuits.

Pre-Wired with Cable Disconnect: The standard Hirschmann interconnection provides easy installation and maintenance of the Flow Alarm and the system it is a part of.

Economical Protection: This monitor rapidly pays for itself as it “sounds the alarm” on incorrect pneumatic, lubrication or cooling volumes, protecting expensive equipment and reducing downtime.

Real-World Applications


Cooling in Circuit Board Production

Semiconductor fabrication facilities use specialized chillers to maintain consistent temperatures and prevent equipment from overheating by circulating cooling water through critical equipment. To ensure efficiency and avoid downtime, AW-Lake’s Variable Area Flow Alarms monitor flow rates of cooling water to these chillers. These flow alarms alert users when flow rates deviate from set parameters, enabling automated controls to correct issues promptly, which in turn helps maximize process efficiency, protect expensive equipment, and reduce manufacturing costs and downtime.

Bearing Lubrication in Mining Equipment

Stone crushers in the mining and cement industries grind rocks into smaller particles, using various types of crushers, each employing bearings to support loads and allow for misalignment. Bearing damage can occur from contamination or inadequate lubrication. AW-Lake Flow Rate Alarms are integrated into the crusher lubrication system to monitor oil flow and alert operators of minimal flow conditions, ensuring proper lubrication and preventing premature bearing wear and equipment downtime.

 

Steel Mills Spray Protective Layer of Oil

In steel mills, hot oil is sprayed on coil steel to prevent scaling, which is the formation of oxide layers on the steel surface at high temperatures. This protective oil barrier minimizes oxidation, preserving the steel’s quality. Flow meters monitor the hot oil flow rate, ensuring the correct amount is uniformly applied, optimizing protection, and reducing waste. They provide real-time data and alerts for deviations, allowing immediate corrective actions to maintain efficient scaling prevention.
