It measures 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 collection on the flow sensors. An increased focus on energy saving has led to ventilation systems requiring low minimum flows. The low flows are a problem since they are very difficult to measure and it is makes it difficult to control the ventilation system. UltraLink, the new technology can measure lower than today s products while maintaining measurement accuracy. This offers great advantages for the user in terms of comfort and savings in energy consumption, which is of great interest. 2

Monitor Overview Display unit Sensor body Flow sensor Display unit Status light Air flow direction CE-mark Status Airflow IP42 IP classification Patented button Monitor FTMU Display parameters Description Application Monitor The monitor is suitable for measuring air flow and temperature. Air flow direction Design The monitor consists of a sensor body with Lindab Safe gaskets. Two flow sensors are mounted on the sensor body and connected to a display unit. The display unit is mounted ontop of a shelf on the sensor body. RTU Note! The flow sensors are placed at a fixed distance to each other and they shall never be removed. TCP/IP 3

4 Mounting Mount the sensor body into Lindab s air duct sytem according to the mounting instructions for Lindab Safe. It is important that the sensor body is mounted with the air flow direction arrow pointing in the direction of the air flow. Do not use the flow sensors as handles when you mount the monitor since they may break and changes in their positions might effect the measurement accuracy. The monitor can be connected to an RTU (remote terminal unit) via RS485 communication, the RTU can then be connected to a computer via TCP/IP Modbus. To be able to connect cords to the terminal board the rubber cable grommet on the backside of the display unit must be punctured, preferably using an awl or something else pointy to ensure tightness to the environment. When the cords have been connected they must be strain relieved. The cords can be attached to the shelf by using cable ties that are attached around cut outs in the shelf. Connections Connections are made in the terminal board which can be accessed when the cover of the display unit is removed V, power supply (AC/DC) 2.

Connect A on the RTU to -A on the monitor and B to +B. When connecting more than one monitor in series it is important to keep connecting A to A and B to B since crossing them will stop Modbus from working. 4

5 Power supply Transformer sizing The needed size of 24 V AC transformer(s) can be defined by adding up the dimensioning power consumption [VA] of all the components. The transformer power must exceed this. Use only safety isolating transformers. Calculation of the current demand I: where: I = (P1+P2+ +P n ) / U [A] P n is the dimensioned power consumption for each component [VA] U is the voltage (24) [V] If the current demand I exceeds 6 A ( which corresponds to approximately 150 VA for a 24 V AC transformer ), it is necessary to use more transformers to prevent overheating. Supply cable sizing The wire size of the supply cable can be determined by calculating the resistance pr per meter R. The calculation presupposes that a voltage drop of e.g. 2 V is accepted in the supply cable: where: R(per m) = U drop / (I * L) [Ω/m] U drop is the accepted voltage drop (2 V) in the cable [V] I is the current [A] L is the longest distance of supply cables from transformer to a component [m] Power consumption The power consumption for dimensioning supply cables for an UltraLink Monitor is 0,48 VA. If using a power transformer with 75 VA capacity it is possible to connect about 150 UltraLinks together. It is not recommended to use a transformer with a higher capacity than 150 VA!

8 ID-numbers The monitors have from production been given an ID-number between 1 to 255. The given ID-number can be seen on the label on the outside of the box the monitor is delivered in, the ID-number is the same as the three last digits in the serial number. If two or more monitors have the same ID-number it is necessary that each of them get an unique ID-number to allow communication. To change the ID-number of a monitor all other monitors with the same ID must be disconnected.

14 At Lindab, good thinking is a philosophy that guides us in everything we do. We have made it our mission to create a healthy indoor climate and to simplify the construction of sustainable buildings. We do that by designing innovative products and solutions that are easy to use, as well as offering efficient availability and logistics. We are also working on ways to reduce our impact on our environment and climate. We do that by developing methods to produce our solutions using a minimum of energy and natural resources, and by reducing negative effects on the environment. We use steel in our products. It s one of few materials that can be recycled an infinite number of times without losing any of its properties. That means less carbon emissions in nature and less energy wasted.
