1.3 Considerations
1.3.1 Functional
The Rosemount 1195 produces the most accurate and repeatable measurement when it is used
in single-phase flow or steam flow above the saturation temperature. Location of the
Rosemount 1195 in pulsating flow will cause a noisy signal. Vibration can also distort the output
signal and compromise the structural limits of the flow meter.
Mount the Rosemount 1195 in a secure run of pipe as far as possible from pulsation sources
such as check valves, reciprocating compressors or pumps, and control valves.
Install the Rosemount 1195 in the correct location within the piping branch to prevent
measurement inaccuracies caused by flow disturbances.
Process temperature limits for direct mount applications is from –40 to 450 °F (–40 to 232°C).
Process temperature limits for remote mount applications is –112 to 554°F (–80 to 290°C).
Contact DP Flow specialists on availability of special all welded designs for applications with
process temperatures as low as –320 °F (–195 °C) or as high as 850 °F (454 °C).

4.2 Troubleshooting
If a malfunction is suspected despite the absence of diagnostic messages on the communicator display,
follow the procedures described below to verify that the flow meter hardware and process connections
are in good working order. Always approach the most likely and easiest-to-check conditions first.
Table 4-1. Troubleshooting
Symptom Possible cause Corrective action
• Is the flow arrow pointed in the direction of the flow?
Improper installation
System leaks Check for leaks in instrument piping. Repair and seal all leaks.
Contamination/plugging Remove the flow meter and check for contamination.
Questionable accuracy
or erroneous flow signal
Spiking flow signal Two -ph ase flow
Spiking flow signal
(stream service)
Milliamp reading is zero
Electronics not in
communication
Milliamp reading is low
or high
No response to changes
in applied flow
Low reading/high
reading
Closed valve
Connections (remote mount only)
Entrapped air
(liquid and steam applications)
Operating conditions
Improper insulation
(vertical pipes only)
Excessive vibration
• Verify that the cross reservoirs are perfectly level with one another.
• Is there sufficient straight run upstream and downstream of the flow
meter?
Verify that both HI and LO manifold valves are open.
Verify that vent, equalizer, and line valves are properly
positioned per the “start up procedure.”
Verify that the high side of the electronics is connected to the
high side of the flow meter. Check the same for the low side.
Are there uneven water legs caused by air entrapment in the
instrument connections? If so, bleed air.
Are the operating conditions in compliance with those given at
the time the flow meter was purchased?
Check the flow calculation and the fluid parameters for
accuracy.
Double-check pipe inside diameter for proper sizing.
The flow meter is a head measurement device and will not
accurately measure a two-phase flow.
Added insulation may be required to ensure that a phase change
occurs at the cross reservoirs.
Check the impulse piping for vibration.
• Check if power polarity is reversed
• Verify voltage across terminals (should be 10–55 Vdc)
• Check for bad diode in terminal block
• Replace electronics terminal block
• Check power supply voltage at electronics (10.5 Vdc minimum)
• Check load resistance (250 ohms minimum)
• Check if unit is addressed properly
• Replace electronics board
• Check pressure variable reading for saturation
• Check if output is in alarm condition
• Perform 4–20 mA output trim
• Replace electronics board
• Check test equipment
• Check impulse piping for blockage
• Check for disabled span adjustment
• Check electronics security switch
• Verify calibration settings (4 and 20 mA points)
• Contact factory for replacement
• Check impulse piping for blockage
• Check test equipment
• Perform full sensor trim (if software revision is 35 or higher)
• Contact factory for replacement

Table 4-1. Troubleshooting
Symptom Possible cause Corrective action
• Check impulse piping for blockage
Erratic reading for
pressure variable
• Check damping
• Check for EMF inter ference
• Contact factory for replacement
Check flow direction
Check that the side of the orifice plate marked “Inlet” is facing upstream. If the DP transmitter is remote
mounted from the Rosemount 1195, be sure that the impulse tubing is connected correctly from the
Rosemount 1195 to the DP transmitter (high to high and low to low).
Check orientation
Improper orientation can result in inaccurate measurements.
Check zero
The transmitter may read off in the high or low direction if not zeroed properly at start-up/commissioning. Refer to the appropriate transmitter reference manual for additional information.
Operation and Maintenance
December 2017
Check valves
The correct valve setting for flow measurement are: equalizer valve fully closed, high and low side valves
fully open.
Check configuration/scaling
Is the 20 mA DP URL of the Rosemount 1195 set properly? This may involve sizing the Rosemount 1195
in the Toolkit Software program to confirm.
Confirm the DCS or PLC and transmitter on Rosemount 1195 are scaled consistently.
Is the square root being taken in the DCS or transmitter attached to the Rosemount 1195? The square
root should not be taken in both places.
Check Rosemount 3051SMV configuration
If a Rosemount 3051SMV Transmitter is being used, its enhanced functionality should be taken into
account during configuration and troubleshooting. The square root should not be taken in the DCS if a
Rosemount 3051SMV Transmitter is being used.
See the Rosemount 3051SMV Reference Manual
4.3 RTD Maintenance
To test the 4-wire RTD (refer to Figure 4-1 on page 24):
for additional information.
1. Disconnect power from the electronics.
2. Remove the temperature terminal housing cover.
3. Disconnect the RTD lead wires from the terminal block.

5. Check that the resistance measured between the two red wires is the same as the resistance
measured between the two white wires within +/- 0.1 ohms. Take note of the resistance value
measured between the two white wires for use in step 6.
6. Measure the resistance between one red wire and one white wire. Subtract the resistance measured
in step 5 from the resistance measured in this step. Refer to Table 4-2 on page 25 to determine if this
resistance matches the temperature that the RTD is in contact with.
7. Check the resistance between any wire and the RTD head or sheath. An acceptable resistance is 200
K ohms or greater.
8. If any of the above measurements are not within the acceptable range as stated above, contact an
Emerson representative for a replacement RTD.
9. To return the RTD to service, connect the lead wires as shown in Figure 4-1.
10. Replace the Temperature Terminal Housing cover.
11. Re-connect power to the electronics.
