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?

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

Gerard

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

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)

How to configure the rosemount 702Dx42 as a discrete output on DeltaV?

Emanuel — Mon, 29 May 2023 13:02:58 GMT

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 wireless THUM

MPHymel — Sat, 22 Oct 2022 20:03:24 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

Reference Accuracy of 3051 with respect to Turndown

Shaiq Bashir — Thu, 30 Jun 2022 17:52:56 GMT

Dear Emerson Support

I need to confirm the calculation of Reference accuracy of 3051SCD2 Ultra Differential Pressure Transmitter. The datasheet says:

±0.025% of span;

For spans less than 10:1, ±(0.005 + 0.0035[URL/Span])% of span

So the question is what does it mean that Span is less than 10:1. Does it mean that when URL/Span <10 then we should use ±(0.005 + 0.0035[URL/Span])% of span

and when URL/Span >10 we should use ±0.025% of span

Because what I understand that as we use a larger turn down ratio, the accuracy of the equipment goes down (gets worse). Can you please confirm this understanding?

5408 Radar Level Transmitter

VetkarNikhil — Wed, 08 Jun 2022 06:33:46 GMT

My question is to Mr. Ingemar Serneby. We are using a Radar Level Transmitter Model 5408 for solid Urea Granule level measurement in a silo. We are facing a repetitive issue with the transmitter. The value gets stuck at 66% even when the actual level in the silo is zero. Once Reset the transmitter reads zero correctly however during the next cycle when the silo is empty the value jumps to 66% and stays there.

Please advice to trouble shoot the issue.

3051C with 199 seals, thoughts about "seal effect"

radiotron — Thu, 02 Jun 2022 20:26:38 GMT

We measure the level in a small propylene vessel using a 3051C with 1199 capillary seals. It is a balanced system. During warm weather, we experience a positive zero shift in the measurement. The transmitter is only spanned from 0 - 13 inH2O, and the vessel is normally only vapor - think of it as a knock out drum. And our installation isn't ideal since the capillaries are probably much longer than necessary to reach the process nozzles.

I just re-read the Emerson white paper that discusses tuned systems vs. balanced systems, and I believe I understand what is going on. I'm sure a tuned system with an appropriate length low side capillary would perform better than what we have. But I'm curious if just raising the transmitter would cancel out the change in density to the point where the error is cancelled out? If so, what would the right elevation be? Even with the top tap, centered between the taps?

Thanks for your thoughts,

Kevin Schroeder

Radar Level transmitter 5400 - Weak strength signal

Sergei — Wed, 31 Mar 2021 04:31:03 GMT

Dear All

We have problems with two level transmitters 5400. During a day "Strength Signal" can change from 6000 mV to 150 mV.

When "Strength Signal" near 150 mV transmitter loses a level time to time. It happens every day.

We've done:

1. Reset the transmitter to a default settings and reconfigured it.

2. Cleaned the antenna many times.

3. Checked a connection between a flange and a transmitter head - no moisture and dirty.

4. Tried different configurations - the same situation (foam, turbulent, foam + turbulent , different the "Product dielectric", different the " Tank type" ).

5. Tried different thresholds from 400 mV to 50 mV, but the transmitter loses a level time to time.

Conditions:

1. The walls of the tank are made of concrete.

2. The high of the tank is 4600 mm

3. The tank contains produced water from a refinery plant.

4. We don't use a stilling well.

On the tank we have two level transmitters 5400 and their behavior is the same.

What can we try more?

Below are screenshots of transmitter:

Rosemount Transmitter Signal Failure

Tushar Gohad — Mon, 01 Mar 2021 10:15:53 GMT

Hello,

Hope you are all Safe & doing Great!!!

The Rosemount Pressure Transmitter 2051 H7 are installed at site. the qty may be 2000 plus. Device Details: 2051, Dev Rev 10, DD Rev03, HART7, Manufacturer ID: 0026, Device Type ID: 2655

For some of the transmitters, we are facing problem about signal drop suddenly. The workaround we performing right now is to remove & insert AI CHARM (DeltaV), then device become healthy & we get the signal from field.

Please suggest possible causes & points to check to resolve this issue.

Thanks... Take Care..

Process temp limit for the pressure transmitter

HABIB UR REHMAN — Tue, 23 Jun 2020 11:19:55 GMT

I am introducing a High-temperature F.G to an existing process line in which instruments are installed (pressure transmitter 2051T silicon filled fluid). want to do a check that the existing instruments will withstand the new high temperature. Which engineering/technical document will give me that information. I looked in the datasheet which shows to derate the ambient temperature with 1.5:1 ratio and we can use up to 121 C. what is the factor of safety, what will happen if I use the same type of transmitter on 230 C process temperature? any idea!

Thank you
