NWM ULW is the ultrasonic water meter having the size from Dn50 to Dn200, designed and manufactured by NWM.

WORKING PRINCIPLES:


The sound wave that flows in the direction of the stream moves faster than the one that flows against the stream.
The transit times Tab (Transit time of ultrasonic waves from sensor A to sensor B) and Tba (from sensor B to A) are measured continuously. The time difference (Tba - Tab) is directly proportional to the mean flow velocity (Vm) of the liquid. The flow rate is a result of the velocity multiplied by the cross section area of the flow tube size.

CHARACTERITICS:
No moving parts permitting the most reliable and longer term life; lowest pressure loss; 

Battery life: ≥4years; possible to keep the external Battery bag for easy to exchange;
AMR ready for RS485, M-BUS...;
