GSM-based Aquamaster 3 Flowmeter problem (+ photo)
I have a problem in 4 Aquamaster 3 gsm-based flowmeters. As you see in the attached photo, the flowmeter has no information from ABB. That creates a problem in its communication with Zeechart software. Does anyone know how to solve this problem? Pleeeaase, It is an urgent case, we have to start up the project asap.
