Page 14: Volume Display Options
Volume Units of cumulative traffic can be changed by Modbus. Communication Output Modes Ultrawater ultrasonic water meter has three output modes. The three output modes are integrated into a communication module. The three output modes are all passive output through connecting wires. It needs external 8-24V AC/DC power supply. -
