The MWN Woltmann Cold Water Meters are commercial sized meters for larger applications. Their design allows for bulk flows of water to be monitored in either a horizontal or vertical installation position. The maximum operating temperature is 30°C for the MWN when used on Cold Water applications. In recent years the MWN has seen improvements to its calibration which means it can measure the flow of water over a wider range of flow rates.
The MWN Meters are all MID approved for Billing requirements and also hold the WRAS approval making them safe to use on Potable Drinking Water installations.
All of the MWN Meters have a PN16 Flanged connection as standard from 40mm right up to 300mm. There is the option of a BSP Union connection for the 50mm though, a unique design of Woltmann meter with a 2" BSP Male connection.
Pulsed versions of the MWNs are available in the form of MWN-NK Models which include a reed switch and cable to wire to. The output ratios vary between 10 litres per pulse and 100 litres per pulse as the sizes of meter are increased but all models can be changed to meet ratio requirements from 10 litres per pulse up to 1000 litres per pulse. Just like the JS and JSC ranges from PoWogaz, an M-Bus output is also available giving the MWN the suitability to be used on either a wired or wireless M-Bus network.
