Ultrasonic water meter DN13-DN50

GALONMETER GL-UL-15-50 is the ultrasonic water meter having the size from Dn15 to Dn50, designed and manufactured by GALONMETER.

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;

1) R400/R250, wider dynamic range
2) U0/D0
3) Lowest flow rate: 2L/h
4) Free from influence of impurity and magnetic field
5) 12+ years’ lifetime
6) Vertical/horizontal installation
7) LCD display
8) IP68 protection, able to work normally under water

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