SwemaMan 7 is a micromanometer for differential pressure:
Air flow and air velocity:
It has a wide range with good accuracy, low position dependency and a resolution of 0,1 Pa.
SwemaMan 7 measures airflow with the use of a k-factor, it can also give an accurate measurement of air velocity when connected to a Pitot static tube (according to EN 16211 method ID 1, ID 3, ST 1, ET 1). The air flow can be displayed using the air velocity and the duct area. The area can either be entered as diameter, height x width or area.
Measurement values are stored automatically and easily transferred to a PC. It is also possible to set the temperature and barometric pressure for density compensation.
SwemaMan 7 has display light.
Differential pressure: -1000…9999Pa
Resolution: 0,1 Pa, 1 Pa at 1000...9999 Pa
Air velocity: 2...129m/s, 390…9999fpm (calculated)
Measurement uncertainty (at 23°C ±5°C):
Differential pressure: ±1% read value, min ±0,5Pa (after zeroing)
(Uncertainty according to GUM (JCGM 100ː2008) using a coverage factor of 2, which for a normal
distribution corresponds to a probability of 95%. It is important to correct the measurement values with
the corrections stated in the calibration certificate to obtain the above uncertainty.
