Solving Problems with Yokogawa Mass Flow Meters
Thread Content
New Yokogawa mass flow meters (Rotemass3 series, split-type RCCF31+RCCS3) were installed on-site; after installation only the range was adjusted. It was found that the transmitter displayed a mass flow rate of 0 kg/h, while the control room showed a fixed flow value. What additional settings are needed for the transmitter? Urgently seeking help. . .
You need to check whether 485 communication is being used or analog signal output is employed; for analog signals, current is measured, while for 485 communication, it is necessary to verify whether the address has been entered incorrectly.
With a transmitter in use, are the current or voltage signals normal?； Moreover, the signal formats collected by remote transmission flow meters and those of local display flow meters are different
First, measure the current to see what its value is, then check the output; it can be connected using HART directly
An menu tree for the Yokogawa mass flow meter is uploaded for your careful review.
Thank you all for your valuable suggestions. .
Call the Yokogawa manufacturer; they will communicate with you and help resolve the issue. I had problems with a previous Yokogawa product, and the manufacturer was very patient, staying in touch with me until the problem was solved
The HK-CMF mass flow meter can be used; the domestic version is also quite good
Use Hart communication to make adjustments first; this is a universal menu. The settings at the control panel may vary, so check the wiring first, and then verify whether the settings such as the range are consistent
It seems that the signal is disconnected; the on-site display shows 0, while the central control panel shows a fixed value
