Yes. Ultrasonic flowmeters can be easily integrated into PLC or DCS systems through standard industrial signal outputs and communication protocols.
Most ultrasonic flowmeters support multiple output options, such as 4–20 mA analog output, pulse output, relay (alarm) output, and RS485 digital communication. These interfaces allow seamless connection to PLCs, DCS systems, data loggers, and other control or monitoring equipment.
For digital communication, ultrasonic flowmeters commonly support Modbus RTU protocol over RS485, enabling reliable real-time data transmission over long distances. Key process variables such as instantaneous flow rate, totalized flow, flow direction, and diagnostic status can be read directly by the PLC or DCS.
The 4–20 mA analog output is typically used for continuous real-time flow monitoring, while pulse outputs are suitable for flow totalization or batching applications. Relay outputs can be configured for alarms, such as high flow, low flow, or system fault indications.
By integrating an ultrasonic flowmeter into a PLC or DCS system, users can achieve centralized monitoring, remote data acquisition, automated process control, and improved system efficiency. Proper wiring, parameter configuration, and communication setup should be carried out according to the instrument manual and the PLC/DCS system requirements.
