Keyence Compressed Air Ultrasonic Flow Meter FD-G Series (FD-G25, FD-G50, FD-G125, FD-G200)
Keyence Corporation Clamp-On Ultrasonic Compressed Air Flow Meter
FD-G series
The FD-G Series Clamp-on Ultrasonic Gas Flow Meter can be easily installed from outside the pipe with only a screwdriver. The clamp-on design greatly reduces installation costs by eliminating the need for pipe modification. Detecting flow from outside the pipe eliminates the risk of restricting or blocking the flow of gas. It also eliminates the risk of leakage from new fittings. The device is compatible with stainless steel and iron pipes from—3/4" to 8"—and can measure compressed air, nitrogen, and other gases.
The high-accuracy measurement, paired with a minimum sensitivity of 0.018 CFM, can be utilized for both large flows and incredibly small leaks. The high-definition display can also show both the total flow rate and the current flow rate for a set period, at the same time. Necessary functions for air management are also included, such as automatic leak volume measurement and monetary conversion.
Optimize Compressed Air Usage Through Metering
- Determine air usage baseline at your facility to identify operational efficiencies
- Monitor specific machine drop points or branch pipes. Ranging from 0.75" to 8" diameter
- Identify cost-saving actions such as replacing valves, leak repair at quick connect fittings and optimizing your compressor's operational efficiency.
Simple Clamp-On Ultrasonic Non-Invasive Installation
- Mount in minutes with no special tools or knowledge
- Completely non-invasive flow meter design means no added leakage points
- Compatible pipe sizes include 0.75"-8"
Measure Air Consumption and Analyze Data
- Record compressed air usage and leakage amounts over time through the onboard display or integrate to an external SCADA system such as PowerRadar.
- Network communication options seamlessly integrate data through open protocol
- Use as a powerful energy savings tool to continuously measure and improve on operations.
