Air Flow capture - SwemaFlow 125D
SwemaFlow 125D measures both supply and exhaust air from low 2 to 125 l/s, 7 to 450m3/h, 4 to 260 CFM, together with temperature and barometric pressure. SwemaFlow 125D is based on the well known Swema principle, a net of hot wires, which gives a good and accurate mean value of the air flow in the capture opening.

This principle makes it also possible to cope with the airflow from angled outlets.

Display
A digital display can toggle inbetween l/s, m3/h, °C, hPa. (A PC-setting sets the units to CFM, °F, inHg)

When turning ON by pressing red and blue button the display light is illuminated.

Pressure drop compensation
Use the "back pressure method" and take two measurements, one with a restriction ring and one without, to compensate for restriction and make measurements with high accuracy, even in low pressure ventilation systems. SwemaFlow 125D calculates the uninfluenced flow rate. The back-pressure method has proved to have good accuracy, with a total standard measurement error (67% coverage), including the method, of less than 10%.

Air Flow scaling
Apart from the Back-pressure method it is possible to show the flow multiplied with a Flow Factor. This is good when balancing the flow and Flow Factor is calibrated with the backpressure methode. A Hold function can look the measuring value when it is hard to see.

Measuring
The flow capture’s measuring unit is equipped with two handles which you hold when pressing the capture onto the outlet.

The measured values are easily stored by means of a button on the measuring unit. The capture incorporates a chargable battery and a fast and efficient charger. Charging takes one or two hours and is sufficient for a normal working day.

Barometer, temperature
Densitety compensation is possible since temperature and barometric pressure is measured. Select Actual or standard flow with PC-setting.
