Depending on transducer used, the Stuf-300Sx product family comes as three varieties: Stuf-300SB clampon ultrasonic flowmeter, Stuf-300SC insertion ultrasonic flowmeter and Stuf-300SG flow-cell ultrasonic flowmeter. All of them have better than 1% accuracy.

Selection Guide:
For high accuracy » Stuf-300SG
For pipe ≤ DN25 (1”) » Stuf-300SG
For long-term stability and zero maintenance » Stuf-300SC or Stuf-300SG
For non-intrusive » Stuf-300SB

Main Features and Benefits:

• Solar powered. No other power supply is needed. Solar panel rated at 2.5Watts
• Built-in rechargeable battery (12AH) and charging circuit
• Robust, weather-proof enclosure
• High accuracy. Normally ±1%. Could be 0.5% when in-situ calibration is available
• No moving parts to worn out, thus, long life-span.
• No maintenance required, thus, low operation cost
• No pressure drop, no flow disturbance. Big savings on high pressure pipes
• Excellent long-term stability. System accuracy does not degrade over time
• Bi-directional
• Wide flow range. Large turn-down ratio
• Suitable for all commonly used pipe materials
• Suitable for most pure liquids and liquids with minor particles
• Robust performance due to proprietary signal quality tracking and self-adaptation technology
• Built-in flow totalizers
• Internal data logger: last 512 daily net flow values and last 128 monthly net flow values
• External data logger (optional): 32,000 data capacity. USB interface
• StufManagerTM PC software for easy programming
• Isolated RS-485 interface with power surge protection. Support MODBUS. Well suited for reliable networking
• Versatile inputs/outputs, such as isolated 4-20mA output, pulse output, analog inputs
• Environment: -10°C ~ 70°C (14°F ~ 158°F) for main unit, 40°C ~ 100°C (-40°F ~ 212°F) for transducer
