GWR 5300 prope issue

Haitham — Mon, 01 Jun 2026 11:19:21 GMT

Dear All,

we have issue with the below GWR 5300 propoe as its bend during installation as in photos below, when we cheked the device in hart communicator outside tanks ist shows healthy but we cant make sure its will be healthy and its integrity for real operation as its used for ESD safety signal.

please advise.if its can be fixed inany way or we need to change all the propoe?

thanks

You need a complete replacement of probe and flange. Transmitter will be okay. The flange has a stud that has the seals. The stud is bent. The probe looks a little bent from top of thread to that weld. Replace both. This happened to me once but it was shipping that caused the overweight flange to bend the stud and probe in the shipping box.

WinSetup crash while changing DAU address

alekseib — Fri, 02 Jan 2026 12:24:37 GMT

I tried to change the address of the new DAU board in WinSetup, but the write operation hangs, and after canceling it the program closes with this error. What could be the problem?

Read data from 2460 system hub via Modbus

alekseib — Tue, 24 Sep 2024 10:31:23 GMT

I'm trying to get data (levels, temperatures) from 2460 system hub to FUEL-FACS+. I use port 7 in 2460 system hub for this, configured to emulate 2160 FCU. Unfortunately FUEL-FACS+ does not support data presentation in 2460 system hub. The communication is successful, but it is limited to 32 tanks, despite the fact that we have 34 of them. How is possible to get missing data from remaining two tanks?

RE: Read data from 2460 system hub via Modbus

jesse.moralina — Fri, 04 Oct 2024 07:33:25 GMT

Hi alekseib . We consulted with our expert on this; and this is the response:

You are running the 2460 in a mode where it is emulating the behaviour of the older 2160 FCU. This older unit only supported 32 tanks, so the modbus mapping for a 2160 only supports maximum 32 tanks.

This information can be found here https://www.emerson.com/documents/automation/product-data-sheet-rosemount-2460-system-hub-en-104538.pdf

"Rosemount 2160/2165 emulation Host protocol, supporting the Rosemount 2160/2165 Field Communication Unit input register mapping. Enables the replacement of Rosemount 2160/2165 without re-programming the host. The maximum number of tanks is reduced to 32 when using 2160 emulation."

The recommendation is to see if the standard 2460 mapping could be used instead or maybe using a user defined mapping.

RE: 3051 Total Performance Calculation

Brad Burton — Wed, 10 Jul 2024 20:56:33 GMT

Gerard,
The 3051C Ranges 2-5 all carry the same reference accuracy specification for the cited 1:1 to 5:1 rangedown limit which is ± 0.04% of calibrated span.
We then use a root sum of squares approach to combine reference accuracy, static pressure effects, and ambient temperature effects.
Please feel free to reach out to me with any more questions you have at brad.burton@emerson.com.

3051 Total Performance Calculation

Gerard Nagle — Wed, 03 Jul 2024 11:59:12 GMT

Hi there,

In the Rosemount 3051 Product Data Sheet 00813-0100-4001, Rev WE April 2023, on page 76 there is a statement on the Total Performace of the transmitter.

As the 3051 has different reference accuarcies for different ranges and so on, how is the +/-0.14% value calculation arrive at?

Many thanks

Hi there,

I have a 3144P transmitter with model number 3144PD2F1NAA01M5WR3C4Q4GMXS

Can anyone tell me what the C4Q4GMXS is as I can not see where to get it.

Thanking the community in advance

Gerard

Hi Michael,
Thanks for the reply and the clarification of the model number.
I just assumed that the naming convention would continue on, not jump back for extra options.
Many thanks

RE: 3144P Temprature transmitter model code query

Michael Olivier — Thu, 27 Jun 2024 14:35:17 GMT

Hello Gerard

Below is a breakdown of these option codes:

C4: 5-Point calibration
Q4: Calibratoin Certificate
GM: A size mini, 4-pin male (minifast) Conduit Connection

We do not have an "XS" option on the 3144P. Perhaps this is option "XA", which means that the transmitter was assembled to a sensor at the original time of order and build at an Emerson factory.

Below is a link to a the full product datasheet for the Rosemount 3144P Temperature Transmitter, which can help you understand what each option code means.

RE: Lower trim on absolute pressure transmitter

Lower trim on absolute pressure transmitter

ThalesCamargo — Sat, 13 Apr 2024 23:34:44 GMT

Good day support team, many thanks in advance for your valuable feedback. Could you please help me with this technical clarification?

Target: Calibrate Absolute pressure transmitter (Hart) which has a range: 0 - 200 psia (absolute)

I would like to reinforce this point: from the Rosemount manual, a recommendation states: Do not perform a Zero trim on Absolute pressure transmitter (since they are reference to absolute zero, really difficult to reach).

If zero sensor trim is not highly recommended, a Lower sensor trim is an option to be performed. How Can I perform this Lower sensor trim in an absolute pressure transmitter without altering the factory curve?

This transmitter is installed at site which has an atmospheric pressure of 14.69 psig (provided by marine department). In addition to that, we can get the information by using an Absolute pressure module Fluke 700PA6 connected to the Fluke 754. From the Fluke the Atmospheric pressure is 14.74 psig. Considering that the Fluke is more accurate, so the considered atmospheric pressure will be 14.74 psig.

Is it correct to perform the:

Lower sensor trim at 14.74 psig and

Upper sensor trim at (200 -14.74) 185.26 psig

I just wonder if Both sensor trim could affect the curve (since from Factory, the first point was considered the Absolute zero).

Since, I have never done a Lower trim on Absolute pressure transmitter, if the Lower and Upper sensor trim is done, What happens with the initial range which is 0 - 200 psia?

Many thanks for your support and valuable feedback.

Kind regards,

Thales

RE: Lower trim on absolute pressure transmitter

Brad Burton — Wed, 17 Apr 2024 21:15:29 GMT

In order to maintain the factory calibration, I suggest that you only perform a lower sensor trim.
A lower sensor trim will shift the factory calibration curve to intercept the trim point but will not change the factory calibrated slope of the line.
You need to reference a barometer to perform a lower sensor trim. The atmospheric pressure will generally be less than 14.7 psia unless you are close to or below sea level. Selection of the correct reference for trim will be important to make sure that your offset is as accurate as possible.

Go ahead and contact me directly so we can figure out the best reference source for your case.
Performing a lower and upper sensor trim will alter the factory calibration, which we can recover by recalling factory trim.
Thank you!

Thermowell Design ASME PTC 19.3 TW

LV RAMAN — Thu, 13 Jul 2023 09:10:59 GMT

This is for the Thermowell Specialists.. Need a bit of Advice.. I am in the process of updating the Specs for an end user regarding ASME PTC 19.3 TW. Some of us are aware that PTC 19.3 methodology required the user to calculate the natural frequency through a simple formula that did not account for pipe wall flexibility. The user calculated the ratio of vortex shedding frequency about the tip of the thermowell (wake frequency) to the natural frequency of the thermowell. This design was acceptable if the frequency ratio was less than 0.8 to guard against vortex induced vibrations.A number of thermowells designed in accordance to ASME PTC 19.3 have failed in non-steam service leading to catastrophic consequences. Subsequently ASME issued PTC19.3 TW and updated in 2016, I would like to add the following criteria in the Specs, Pl confirm this approach is good enough for a robust design.

Calculated wake frequency shall not exceed the number in Table below based on information on pipe schedule in data sheets.

Table - Limits of thermowell frequency ratio

Parent pipe schedule (Note 1)	Thermowells
Schedule 160 or greater	< 0,384
Schedule 80 to less than Schedule 160	< 0,372
Schedule 40 to less than Schedule 80	< 0,340
Less than Schedule 40	< 0,168
Note: 1. Treat stainless and non-stainless pipe the same (i.e. Schedule 40S and 40 have the same limit)

RE: Thermowell Design ASME PTC 19.3 TW

timchan bonkat — Fri, 14 Jul 2023 18:03:35 GMT

LV Raman,

Your interpretation of the ASME PTC 19.3 standard is correct, there have been changes that now consider different parameters to ensure the thermowell is not compromised. We adhere strictly to the ASME PTC 19.3 TW 2016 method which shows that the pipe schedule by itself does not directly impact the wake frequency calculations (WFC) calculations. Instead, the standard accounts for the flexibility of the thermowell attachment to the pipe (mounting compliance factor). The 2016 version of ASME PTC 19.3 TW uses an improved frequency calculation with more adjustment factors and accounts for a 0.4 inline frequency limit when necessary (only low density/velocity gas are allowed up to 0.8).).

The 4-frequency ratio values you provided (.384, .372, .340, and .168) are all under 0.4 so they would still be acceptable per the standard. What you’re doing is making the calculations more conservative which in turn may lead to an over designed thermowell. We have a free online software called the Rosemount Thermowell Design Accelerator which ensures your thermowell designs meet the latest ASME PTC 19.3-TW standard plus does a lot more to make sure you have the best product for your application.

I do have one question for you, where did the frequency ratio values you provided come from? Are they part of a standard or vessel code table?

Let us know if you have more questions.

Thanks

Hey guys.
I installed a rosemount 702DX42 to drive a solenoid valve in a tank, but the 702DX42 only appears on DeltaV as an analog input.
Could someone tell me how to use the 702Dx42 in DeltaV as a discrete output?

Proservo NMS5 gauges to Rosemount FCU2460

alekseib — Mon, 07 Nov 2022 18:53:48 GMT

We have E+H Proservo NMS5 gauges connected to Rosemount FCU2460 system hub via RS485 card. How to configure that gauges in the WinSetup? Tried different ways, but nothing worked. When I check the connection with the device, WinSetup physically sees the devices. Where to define the registers of the gauge (level, product and vapor temperatures)?

can't see Rosemount radar level on wireless gateway using a Twiresllwhum

MPHymel — Sat, 22 Oct 2022 20:02:08 GMT

Here is some back ground:

Existing DeltaV DCS v14.3

Existing Rosemount Wireless gateway, talking modbus to DeltaV for cybersecurity reasons

Gateway is AMS ready and several devices on the gateway are available in AMS

Newly installed radar gauge on a tank using a THUM.

The gateway shows the THUM listed on the explorer tab of the web interface, but HART status is red

The gateway shows the level transmitter as good HART status (green) but does not show any last update, PV, TV, SV, QV or Burst data

AMS v14.+ is not listing these devices even when rescanning the gateway node, (full scan of all devices)

Another curious thing, the level transmitter is not listed in the pick list in the Modbus mapping table, like the gateway doesnt know its there, yet it is listed in the explorer view.

Is it possible that the THUM needs to be configured to pass the level transmitter variables? This is not the first application of transmitter, THUM and this specific gateway at our site. for some reason this one is not working, and the THUM doesnt show the same contigent of populated fields in AMS as the working one does.

Any help would really be appreciated, and this post may help others in the future.

Thanks, Mark

Calculating Long Term Stability of 3051S Differential Pressure Transmitter

Shaiq Bashir — Fri, 01 Jul 2022 05:55:13 GMT

Dear Emerson Support

I need to confirm the calculation of Long Term Stability of 3051SCD2 Ultra Differential Pressure Transmitter. The datasheet says:

±0.15% of URL for 15 years;

for ±50 °F (28 °C) temperature changes,

up to 1000 psi (68.95 bar) line pressure

I'm a little confused about how to calculate it. So simple way is to do 0.15% of URL and that will be for 15 years. but how to consider temperature changes and line pressure changes as mentioned above?

Regards

RE: Calculating Long Term Stability of 3051S Differential Pressure Transmitter

Brad Burton — Fri, 01 Jul 2022 18:17:37 GMT

The stability specification allows for variation in both ambient temperature and static pressure as defined in our literature. Within those limitations, the output will be stable to within 0.15% of URL for 15 years.
For simplicity, we often direct customers to use linear interpolation to determine stability over shorter time-frames, which means after 5 years you would expect 0.05% of URL. If you are looking to determine a calibration interval for your installation, I have added a link to a white paper that provides guidance for that calculation.
