Siemens 7ML1034-1AA11 Ultrasonic Level Controller

Siemens Milltronics HydroRanger 200 Ultrasonic Level Controller, model 7ML1034-1AA11, provides continuous, non-contact level measurement for liquids, slurries, and solids in tanks and open channels, with a measurement range of 0.3 to 15 m (1 to 50 ft). It offers six relay outputs for pump control and alarms, two 4–20 mA outputs, and RS-485 Modbus RTU communication to integrate with PLCs and SCADA systems. The unit features a four-button HydroRanger 200 HMI and supports multiple mounting options—wall-mount with standard enclosure or with four entries and M20 glands, or panel-mount—powered from 100–230 VAC. Typical applications include open-channel flow monitoring and level/volume control in wastewater and water treatment, pump-sequence control at lift stations, and bulk-liquid management in process facilities.
