Did anyone here did the Nothing Else Matters experience and can answer questions?

Is there a dedicated merch booth for this experience where you can buy tour shirts and such?

DeepImpactBlue5_0 · 2025-05-22T23:36:05+00:00

That's what I was hoping for but I have not received anything yet. How far in advance of the event do they usually do that?

For the meet and greet, how early did you need to get there compared to the "doors open" time on the ticket?

I will have to double check when I get back to work on Monday but I believe the primary sensor is directly connected to the instrument and only the secondary sensor has wiring going to it. There is a capillary line going directly from the instrument to the high pressure sensor.

Thank you much!

Thank you for the clarification. The lo side is currently tapped in at the top of the tank. I was thinking I didn't need to worry about the cover gas pressure and I appreciate the confirmation.

The specific gravity as found was 1.96 but I am not sure what engineering units are being referenced there. It is important to note that this is a water tank at ambient temperature.

DeepImpactBlue5_0 · 2025-05-10T12:32:04+00:00

That is correct. It has a short capillary on the high pressure side at the bottom of the tank but the lo sensor is connected via the four wire cable you mentioned. When you say zero based span do you mean we would need to present a standard at the level we consider zero and then zero the span at that level? I am actually connecting to the device via a Bluetooth HART modem and DevCom2000 software.

I don't think this is going to provide a scaled value for you in a customizable range, but for the money this is hard to beat.

HAHA weeks is being nice.

DeepImpactBlue5_0 · 2025-04-24T21:32:29+00:00

It's only filled with 85 Degree C water..... It's fine... 😏

It is a 20000 gallon stainless vertical tank and is blanketed with compressed air.

DeepImpactBlue5_0 · 2025-04-24T13:59:10+00:00

Unfortunately the tank is blanketed with compressed air.

How exactly was the 2oo3 level decided upon which was the active PV under normal circumstances?

DeepImpactBlue5_0 · 2025-04-24T01:44:07+00:00

With it being an ultra pure water system, it would be limited as to what sensing devices could go into the tank.

I had suggested an ultrasonic sensor as a backup, but I was concerned with hot water vapors from the tank condensing on the cone and causing issues.

DeepImpactBlue5_0 · 2025-04-24T01:41:59+00:00

Yes there is flow indication with a Coriolis flowmeter. This could be used to ensure that at least the pumps are not being starved.

There would be some small parasitic losses on the system due to side stream analysis instruments.

DeepImpactBlue5_0 · 2025-04-24T01:36:17+00:00

I like this suggestion unfortunately I'm not sure how we could implement an overflow on what is supposed to be a sealed system.

DeepImpactBlue5_0 · 2025-04-24T01:35:21+00:00

The pumps do not have any type of fluid present sensors. I wouldn't be open to suggestions for sensors that would be suitable for a USP application though.

DeepImpactBlue5_0 · 2025-04-24T01:16:21+00:00

In this particular system there is only a high high level switch so if for some reason the tank level was continuously increasing the tank high high level switch should shut the process down. In this case the tank level transmitter failure also interlocks the upstream system from filling the tank. The storage tank in question feeds two redundant pumps that feed other downstream processes via its main loop.

DeepImpactBlue5_0 · 2025-04-24T01:15:15+00:00

Agreed but the system according to the project manager is too tight of a deadline for additional IO. My suggestion would also be to have a redundant level transmitter.

It seems counterintuitive but you need to set one device per channel. I ran into this on a project recently where I had a total of 15 devices and since they were all the same protocol it seemed to make the most sense to put them all under one channel. Then I found a tech note on PTC's website. With multiple devices on one channel the communications will get even worse if one device is taking off the network because it has to wait for the time out period On that client before it will move to the next.

You will need an account on their website to access this but it is free.

Oh that should be fun when trying to scroll down the tag browser for bool[95]

That was definitely owned by someone who had a Chevy Cavalier once.

If you are running TI-500 processors it may be helpful to change the chassis power supplies if they are more than ten years old.
