SITRANS FUS1020 offers reliable flow-measurement at a much lower cost than other clamp-on ultrasonic flowmeters, with flow rate accuracy of 1% or better for most applications.
Особенности
- Low initial cost
- Easy installation; no need to cut pipe or stop flow
- Minimal maintenance; external transducers do not require periodic cleaning
- No moving parts to wear or foul
- No pressure drop or energy loss
- Compact, integral design reduces installation cost
- Wide turn-down ratio (80 : 1)
- Choice of single or dual channel operation
- Transducers are matched to the pipe material and have menu-driven location
- Wide-Beam technology ensures high performance
- Zeromatic Path automatically sets zero without stopping flow and eliminates zero drift
