SwemaMan 8 is a micromanometer designed for accurate ventilation testing, adjustment and balancing (TAB), aswell as for industry and research applications.

The instrument has a built-in differential pressure sensor and a zeroing valve for automatic zero pressure check. It measures air flow according to EN 16211 and 12599. Air velocity is measured with a pitot-static tube. Air flow is displayed from air velocities across an area or measured on a valve with k-factor. The included barometer and thermocouple automatically compensate the velocity and flow for air density. SwemaMan 8 displays minimum, maximum and average values. The measurements can be stored and transferred to a PC.

Measuring metods:
The micromanometer measures differential pressure. Together with a pitot-static tube the air velocity and air flow in a ventilation duct is calculated. (according to EN 16211 method ID 1) At a supply, exhaust valve or in-duct valve measurement with k-factor and differential pressure can be used. (EN 16211 method ST 1, ET 1, ID 3).
