Problems with E+H mass flow meters
Thread Content
There is a Promass 300 Coriolis mass flow meter on site; the contractor chose a single current output when purchasing it. The current output is flow rate. How can this sensor simultaneously send both density and flow rate signals to the host computer? Please let me know if you have used it.
By contacting the manufacturer, is it possible to replace the output board so as to achieve multi-output functionality, or is it possible to enable communication? Do you mean that the general contractor assigned them as the construction party?
This requirement for output density should be specified at the time of ordering; otherwise, an output terminal for it generally won’t be provided. If HART communication is supported, the density can be viewed on the handheld controller. If multiple parameters are required, then a communication port is necessary.
When placing the order, only single-output was ordered, so I came to Haichuan to ask if it could be upgraded. I can use it as a reference.
There is a display on the gauge; it’s necessary to go to the site and monitor the process manually, but they find that to be a hassle.
If the module on the DCS side supports Hart communication, it can be read. Otherwise, it’s better to send it back to the factory for modification.
If you don’t make a choice at the beginning, it can be a bit troublesome. Some models allow for the addition of a signal output circuit board, while others don’t permit this; in such cases, you need to replace the board. It depends on the specific model. If you have any needs, contact me on QQ at 83691216 – I have some boards available
It seems that an output board can be added to the 80 model
There should be two 4-20mA signals: one for flow rate and the other for density. The HK-CMF mass flow meter produced by our company is of this kind: the first current signal represents the flow rate, while the second signal represents the density
