Flow totalizer plc logic
WebDec 29, 2024 · CSA. Dec 28, 2024. #2. A flowmeter measures the instantaneous flow--in engineering units such as litres-per-hour, or kg-per-minute. A totalizer calculates the total flow--in engineering units such as litres or kg. Some totalizers only count in a certain period, such as one day. Others just keep counting and counting and counting and … WebJan 6, 2004 · Some venodor's multivariable flow transmitters can be configured to send the unscaled flow value via an analog output. You could then scale the value in the PLC, save it to a REAL (or double word) memory register, do your totalizing calc, and then save the result to a "totalizer memory register". It might help to know which PLC you are using.
