Volumetric flow controller in rectangular design, for duct con-
nection to DIN EN 1505, for use in supply and return air systems
for constant or variable volumetric flow, room or duct pressure
regulation. With positive control V

or "CLOSED". Al-
lowed pressure difference range: 50-1000 Pa, allowed ambient
temperature 0-50°C. Suitable for use with duct velocities of 1-12
m/s. It is possible to subsequently adjust the manufacturer set
operation volume flow. The output signal can be used for mas-
ter/slave or parallel operation of several controllers or for actual
value display 2-10 V DC (0-10 V DC), which corresponds to 0-
100 % of the set V
nenn
in DDC/ZLT systems.
Housing made of galvanised sheet steel. Opposed blades,
blades sealing air-tight to DIN EN 1751, Class 3, housing leak-
age air flow to DIN EN 1751, class B, made of aluminium. Meas-
uring rods made of aluminium, blade support made of plastic.
With electric controller LMV/NMV-D3-MF, control voltage 24 V
AC, 50 / 60 Hz, requirement: measuring air 0...+50°C/5...95%
rH, non-condensing, wired and adjusted in-factory. Right-hand

Accessories (at an extra charge):
- galvanised sheet steel with DD coating (-DD)
- Acoustic cladding (-DS2) made of 20 mm sound-absorbing
material with sheet metal casing made of galvanised sheet
steel, non-flammable according to DIN 4102-17. Includes M6
cage nuts at the corner angles.
- Mineral wool silencer (-ZSQ) with M2 Metu profile on both
sides, housing (L=1500) consisting of galvanised sheet steel
with integrated MWK-OB silencing baffles (L=1000). The
MWK-OB silencing baffles, with RAL quality seal, consist of
abrasion-resistant mineral fibre boards covered with fibre
glass filament (biosoluble, non-flammable to DIN 4102) in a
frame of galvanised sheet steel. Baffles measured to ISO/DIS
7235 and to DIN 45646.
- Setting and diagnostic device ZTH-EU (Belimo)
- MP-bus-capable electric controller LMV-D3-MP, NMV-D3-
