SmartFlow SC1: Features and performances
SmartFlow Carac
Principle and performance
Flow meter
  • Diaphragm flow meter with non-constant floating test pressure: At low lift, the pressure is greater than the standard test pressure and at high lift, it’s the opposite.

More representative of the real intake phenomenon

  • Flowmeter in accordance with ISO 5167-2 : Sizing, lengths, positioning of components.

Control electronics
  • The use of high-performance electronics makes it possible to obtain very good resolution. The Flow Control Unit allows the acquisition of the test pressure, the pressure of the primary element as well as the atmospheric pressure. The temperatures in intake and exhaust mode are also measured.


> 32-bit Micro Controller with 12 bits analog to digital conversion

(theoretical resolution of 1/4096 = 0.024% and practical 0.1% )


> Temperature compensated P sensors

  • The calculation of the mass flow Q and volumic Q takes into account the Reynolds number (Re), the temperature and the atmospheric pressure and takes into account the ISO 5167-2 standard.

Measurement uncertainty <1%

  • The software provides automatic zeroing of the instrument as well as digital filtering.

  • The flow is calculated at a standard pressure (10 or 28 inches H2O, industry standards)

  • The repeatability measurement carried out on a calibrated plate over 50 measurements gives a standard deviation of 0.43 for an average of 83.8 CFM.

0.5% repeatability rate

Easy and visual use

Easy to use
Pressure taps

The hoses supplied are connected to the tubing and to the FCU via “push in” type connectors which allows them to be assembled and disassembled effortlessly and quickly. It is very practical to switch from intake to exhaust mode and vice versa.

Even easier with the crossover kit

Temperature measurements

SmartFlow SC1 is delivered with the sensors already installed, just plug in the supplied dedicated cable.

Connection to the shop vacuum

The 63-40 connector supplied makes it easy to connect workshop vacuums.

Connecting the FCU to the computer

The supplied USB cable plugs into a USB port on the PC.
