1.Brief Introduction
鈼?The ultrasonic water meter-213E is a new type of intelligent all-electronic meter. It integrates measurement and display to achieve accurate measurement with a minimum flow of 0.03 m3/h.
鈼?Achieve multi-angle installation and minimize the pipe pressure loss.
鈼?Dedicated to household measurement in residential quarters
鈼?Connect to the GSM wireless concentrator produced by our company, using GSM mobile public network for data transmission to form a wireless monitoring system. It automatically reports abnormal status.
