Introduction
UltraLink
®
FTMU is a highly accurate flow monitor without any obstacles in the airstream that creates pressure drop. It mea-
sures the flow with an angled ultrasonic beam which can be calculated and compensated to a very high accuracy over the
whole flow range. The method is very stable over time due to that it is not sensitive to dirt and the design minimizes the dust
accumulation on the flow sensors.
An increased focus on energy saving has led to ventilation systems requiring low minimum flows. The low flows are a pro-
blem since they are very difficult to measure, which makes it difficult to control the ventilation system.
The new technology of UltraLink
®
makes it possible to measure lower air flows compared to today’s products while maintai-
ning measurement accuracy. This offers great advantages for the user in terms of comfort and savings in energy consump-
tion, which is of great interest.
