Real-World Applications


Air Compressor Flow Rates

Air compressors are widely used across various industries for their safe, energy-efficient and non-heat producing operation. Measuring the air flow to air compressors is important to ensure optimal performance, energy efficiency, and system reliability. Pneumatic flow meters provide accurate air flow measurement that helps in identifying inefficiencies, detecting leaks, and maintaining proper pressure levels, which can reduce operational costs and prevent equipment failures.

 

 

 

Air Consumption in Blow Molding

Pneumatic flow meters are used in blow molding to monitor and control air consumption during the molding process. They measure the flow rate of compressed air supplied to the molds, ensuring that the correct amount of air is delivered for each production cycle. By providing real-time data on air usage, these flow meters help optimize the process, improve energy efficiency, and reduce costs. They also enable early detection of leaks or inefficiencies in the system, allowing for timely maintenance and minimizing downtime. This ensures consistent product quality and enhances overall production efficiency in blow molding operations.

Environmental treatment by air sparging using VA flow meters

Air Sparging Environmental Treatment

Air Sparging is a remediation technique used to treat groundwater and soil contaminated by volatile organic compounds (VOCs) such as petroleum hydrocarbons. This process involves injecting pressurized air into contaminated groundwater, converting hydrocarbons from dissolved to vapor form, which are then extracted. AW-Lake Pneumatic Variable Area Flow Meters provided visual confirmation of continuous air flow at both the inlet and outlet. These flow meters ensure adequate air flow for effective contamination removal, improving soil health and groundwater quality.
