MWN130-NC Nubis — turbine (Woltman) flow transducers for heat meters DN40–300, qp 15–600 m³/h, up to 130 °C
Country: Poland · Model: MWN130-NC Nubis
MWN130-NC is a mechanical turbine (Woltman) flow transducer for compact heat meters in DN40–300 and nominal flows qp 15–600 m³/h. It measures the volume of network water in closed systems from 0.1 to 130 °C at pressure up to 16 bar. It is installed on trunk and distribution heating networks, in heating substations and in commercial heat metering stations with high flows.

Description
The range by qp in m³/h is as follows. DN40 and DN50 (15), DN65 (25), DN80 (40), DN100 (60), DN125 (100), DN150 (150), DN200 (250), DN250 (400), DN300 (600). The face-to-face length is 200 mm for DN40–65, for DN80 (200 or 225 mm), per ISO 4064 on request, up to 500 mm for DN300, weight 7.9–103.1 kg. Flanges are per PN-EN 1092-2 (PN10), DIN 2532, DIN 2501 or BS 4504 as standard, PN16 or ANSI B16.5 class 150 on request. Installation is in horizontal pipelines with the register up (H), and in vertical and inclined ones with the register sideways or in intermediate positions (H/V), without effect on metrology. The MID range is qi/qp 1:25 for DN40–200 and 1:10 for DN250–300, and the magnetic field protection complies with EN 14154-3 and EN ISO 4064-2. The impeller sits on hard bearings on both sides, the measuring insert is replaceable and standardized, and the body is coated with powder epoxy paint. The volume is passed to the calculator by an NC reed sensor with a 2 m cable.
How to choose
The size is selected by nominal flow qp, and the range runs from 15 m³/h for DN40 and DN50 to 600 m³/h for DN300. The transducer is not rated for temperatures above 130 °C. The MID range of 1:25 applies up to DN200, and for DN250–300 it is 1:10. The H or H/V installation position depends on the pipeline and does not affect metrology.
