MICRO MOTION FLOWMETER
One micro motion was insattalled in plant, and working properly but suddenly start fluctuation in output and after that output be 2mA. The sensor is DS600 and transmitter is 1700. Any idea for troubleshooting
I am curious how long your meter was working properly before the fluctuations started. It would also be helpful to know a little about what fluid you are trying to measure, how the sensor is installed (tubes up, tubes down, etc.), and if anything else is happening in the process that you know of (possible flashing of the fluid, changes in temperature or pressure when the meter goes into a fault condition, etc.).
When the output goes to 2 mA, that is a fault condition and an alarm is present. I would start by looking at the 1700 display (assuming it has one) and checking to see what alarms are listed. You can do this by holding your fingers over both of the optical switches (SCROLL and SELECT) for approximately 4 seconds. SCROLL until you see "See Alarm" on the display, then SELECT that option. You should be able to SCROLL through the list and be sure to record the alarms that are present. Table 10-2 on page 168 in our manual (http://www2.emersonprocess.com/siteadmincenter/PM%20Micro%20Motion%20Documents/1700-Config-Manual-MMI-20019028.pdf ) has a list of the status alarms, their description, and some recommended actions to take to clear the alarm. Feel free also to let us know what alarms are present and we can help with the troubleshooting.
I hope this helps.

Hi I checked it by HART communicator, show "sensor/xmtr communication error" and sensor also detect the flow direction (I change flow direction, HART Communicator Show Reverse Flow). I check the core processor LED indicate normal operation
Hi Tonya Thanks Best Regards Mohsenv
