Siemens Answers: How can you get data from your flow meter? | |
December 2020, MARIETTA, GA ~ The easiest and most obvious way to get data from your flow meter is to observe the local display on the meter itself. This method is used frequently in basic applications where a manual observation, and possibly a manual process adjustment, is possible.
But what if you can’t get to the meter’s local display?
There is also the option of sending a signal representing the desired measurement from the display itself. Many meters offer an analog and/or pulse output built into the display. Instead of remote mounting the display, the display remains with the sensing element and the analog or pulse signal is transmitted via wires to a remote display or interface. The advantage of this method is simplification of the wires or cables needed to transmit the signal verses the wires or cables needed to remote mount the entire display. Additionally, this may be the only option if the flow meter does not offer a remote display option. The disadvantage is that a second display or read-out is required to interpret the analog or pulse signal, which increases total meter cost and complexity.
My local display shows a lot more information than I can transmit via analog or pulse. How do I get that information to a remote location?
Of course, the system complexity increases, and a receiver device that understands the selected communication protocol will be required. This option also has the same drawback of having to install wires and cables to transmit data.
I have an analog-, pulse-, or bus communication-capable display, but due to prohibitive costs, I can’t install the necessary cables to transmit my data to my desired remote location. What are my options?
