MWN / MWN130:Cold water R100 ÷ 200 - H, VHot water R 25 ÷ H - Н, VMWN-G / MWN130-G:
Cold water R100 - H, V
Hot water R40 - H, V


Measurement of high cold water consumption up to 30°C or 50°C and hot water up to 130°C, MOP 16 bar (PN16). For installation in horizontal piping with the counter upward (H), in vertical piping with the counter sideways (V), or in sloping piping (H/V). The standard versions of type MWN feature 6-barrel counters and powder-coated cast-iron bodies. The water meters with communication modules (IP65 and IP68-rated) and the special version with the NK transmitter module (IP65-rated) are designed for operation in AMR systems

Horizontal rotor axis propeller water meters (Woltman) (DN40-400)

  • Adapted to the remote readings


  • Resistance to strong magnetic fields


  • Minimum service life - 12 years


  • Application

    Water meters are assigned to industrial measurements of water usage up to 30 degrees of cold water and up to 130 degrees of hot water in relatively regular and strong flaw rate. Construction of the water meter gives possibility of mounting on horizontal, vertical and inclined water supply systems with counter set upwards, sidewards or in medium position H-V.

  • Measurement range

    ● MWN / MWN130 – Cold water R100÷200 – H, V
    ● MWN / MWN130 - Hot water R25÷40 – H, V
    ● MWN-G / MWN130-G – Cold water R100 – H, V
    ● MWN-G / MWN130-G – Hot water R40 – H, V
