The damper DIRU with flow meter offers measurement of the air flow. DIRU has the following characteristics: low noise level, centric flow, fixed measurement nozzles for accurate flow measurement and is equipped with regulating facilities that can be fully opened, which means that you do not need cleaning covers. It fulfils tightness class C. The dimension graph is to be used to determine the pressure drop over the damper with flow meter and to give information regarding the sound effect level at different settings. When balancing the system the balancing graph should be used. There is a separate assembly, measuring, balancing and maintenance instruction for dampers with flow meter. The damper blades forms a measuring flange which allows flow measuring. By measuring the pressure difference between the measure nozzles, you can through the equation on the damper derive the flow q [l/s]. The setting value of the damper and the correction factor (k-factor) is the same number which means that you do not have to read a graph in order to get the k-factor from a setting value. The air flow is regulated with a handle. Ø 80–630 fullfills pressure class A in closed position. Material The damper is made of hot-dip galvanized sheet steel. Installation Consider required straight distance after or before disturbance, as mentioned on the card attached to the measurement nozzles, to obtain accurate flow measurement. Cleaning By fully open the damper, one get access to the duct. Do not forget to readjust the damper after cleaning.

The DTBCU is a spring return damper which closes if the electrical power is off. The damper can be ordered with the following control option. 24 or 230 V on off motor 24 V motor with 2-10 V analog control signal (motortype -SR) 24 V motor with data bus control; Modbus, BACnet, MP-Bus (motortype - MOBA) The motor has overload protection and stops automatically when the blade has reached its end stop. Although the current is connected, the motor is not damaged if blocked. When the power is cut, the damper closes when the drive motor freewheels and the return spring pulls the blade back to its original position. If you want the damper to open instead of close, you can undo the two nuts on the spindle clamp, turn the spindle 90°and tighten the nuts again. In outdoor installation, the motor should be protected from direct UV radiation. The motor is installed at a distance from the damper, which makes it easy to insulate the ventilation duct. There is a separate assembly, measuring balancing and maintenance instruction for this product.

Applications The meter is suitable both for setting up and for continous flow measurement. It is intended for permanent installation and must therefore be specified at the design stage. There is a separate assembly, measuring, balancing and maintenance instruction for this product. Design The meter consists of two reductions joined together, with measurement nozzles. Each nozzle has a removable plastic plug which prevents dirt from entering. It also eliminates air leakage when measurement is not done. The unit permits insulation of up to 100 mm thickness to be installed without concealing the measurement nozzles or label plate. The plate can be rotated for best legibility, irrespective of the way the fitting is installed and can easily be removed, to be located away from the unit. Flow meters with reductions of two dimension steps can be obtained, to give higher reading pressure in the measurement nozzles. This entails higher pressure drop and noise generation, however.

FRU is a measuring unit with a measuring cross used for measuring volume air flow rate in circular duct systems. FRU is equipped with a regulator, providing an output signal that is proportional to the volume air flowrate. FRU can be used to monitor the actual airflow or can be used to control a volume flow regulator. Regulators comes with either flow sensor (D3) for clean air or membrane sensor (M1) for contaminated air. FRU is equipped with Lindab Safe in the front for connection to the duct and a female coupling in the back, and is ready for insulation up to 50 mm. FRU can be installed in any position without requiring adjustment. The FRU needs a certain distance of straight duct before the unit and this has to be observed to obtain a stable and accurate air flow regulation. To avoid clogging of the measuring cross, it is recommended to use FRU only in applications with clean air, meaning free of dust, particles and similar. • Belimo MP, Modbus, BACnet & analogue 0(2)-10V. • Integrated NFC interface, compliable with Belimo Assistant App.
