The GE Panametrics AquaTrans AT600 ultrasonic flow meter has no moving parts and requires minimal maintenance. An on-board microprocessor uses patented correlation transit-time technology for long-term, drift-free operation. Automatic adjustment to changing fluid properties and dynamically configured operating software simplifies programming.
The accuracy in field calibration is ±0.5% assuming installation is a fully developed, symmetrical flow profile (typically 10 diameters upstream and 5 diameters downstream of straight pipe run). Final installation accuracy is a function of multiple factors including fluid, temperature range, pipe centricity, and other influences.
Clamp-on transducers offer maximum convenience, flexibility and a low installation cost compared to traditional flow metering technologies. With proper installation, clamp-on transducers provide better than 1% of reading accuracy in most applications. The AT600 is designed specifically for water and wastewater applications in full pipes, but works with various acoustically conductive liquids. Fluid types include most clean liquids and many liquids with small amounts of entrained solids or gas bubbles.
GE Panametrics AquaTrans AT600 Ultrasonic Flow Meter Applications:
