  • Model : GL-UL-50-600

GALONMETER GL-UL-50-600 is the ultrasonic water meter having the size from Dn50 to Dn600, designed and manufactured by GALONMETER.



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.

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...;
Digital Display:

Main Technical Data: ISO 4064 Class B



From Q1 inclusive up to but excluding Q2 is ± 1%; From Q2 inclusive up to and including Q4 is ± 3%; FOR CLASS II:
