The Coriolis mass flowmeter transmitter does not display anything when powered on
Thread Content
The voltage is normal at 24V, and the fuse is in good condition; it just doesn’t display anything – there seems to be no power. I’m asking experts what could be the issue
What is the loop current? What is the voltage under load?
The voltage under load is 23.67; my meter isn’t capable of measuring the current
Oh, what brand is it? A newly installed watch?
Yantai Zhonglong, I’ve been using it for a few years now. It was working fine before; after being parked without power for a few months, it became like this when turned on again

Oh, today’s field instruments are modular (power supply, main board, display, sensors, etc.), and maintenance usually involves replacing the module to identify the faulty one. Is it possible that there is no display, but the signal output is normal?
It is possible to open the table cover to check what the cause is; if it cannot be found, it is best to contact the manufacturer for repair.
It’s domestic; it’s normal for the electronic circuit to malfunction. Contact the manufacturer and replace the meter head if necessary
There’s a problem with the motherboard; it’s recommended to contact the manufacturer for a replacement
