How to Determine the Best Field Instruments for Awesome Results?

 I warn you that this post is long and maybe you don't have time or in the right places and circumstances to read this, so I'm  going to give you this sign before I start (so you're not going to sue me for this)

Hahahaha. I love it. OK now what? Oh yes.

How to determine what instrument is best for your application?

Well, It require very intense experience to do that. You know it when you have made mistakes and have a change to correct them. Only by facing the problems you can appreciate the impact of instrument selection, documentation, and installation on its serviceability.

Warning! This blog is Boring

The author warns you that this technical blog is long, tired and you're at risk of falling sleep ( I fell a sleep while proofreading this blog). I would recommend you not to read this blog while you're

1. Working at heights

2. Operate Heavy Machinery

The Real Engineering Project Interaction

Project Manager: Okay guys, lets make an unmanned technologically advanced plants that are safe with high yield and LOW COST  in less than a year( with a little number of engineer, no support groups (drafting, computer services, purchasing, etc) and a large number of managers).

Process Engineer: We need you to calculate and design a control valve with the  40 barg pressure drop in 2" line pipe under the choked flow condition.

Mechanical Engineer: We managed to purchase low cost packaged equipment without any electrical drawing, Could you make the shop drawing for us?

Electrical Engineer: We want to put electrical heat tracing on the UPS.

Piping Engineer: We forgot to isolate the pressure transmitter during hydrotest.

Safety Engineer: We want to put water sprinkles in the control room because its cheaper

Instrument Engineer: Arrrrrrrrggggggggggggghhhhhhhhhhh

Orang-Orang yang mencintai Ilmu (Cerita Dr Abdus Salam Dengan Pelajar Jerman)

Disadur dari buku Dr Abdus Salam Poor As A Nation.

Dr Abdus Salam: Orang bilang kemiskinan adalah musibah karena jika sesorang lapar dia tidak punya waktu dan keinginan untuk belajar mengasah kemampuan otaknya. Saya selalu teringat sebuah kejadian di Jerman sekitar 40 tahun yang lalu mengenai masalah ini.

Pada tahun 1947 saya adalah mahasiswa di Universitas Cambridge, Jerman sudah kalah perang saat itu dan seluruh masyarakat jerman sedang merasakan penderitaan karena kekalahan ini.American Control Commission mengundang mahasiswa dari Cambridge dan seluruh Eropa untuk melihat penderitaan yang sedang masyarakat Jerman rasakan.Sekitar 500 orang mahasiswa datang ke Munich dari seluruh Eropa.Saya lihat tidak ada satu gedungpun yang masih berdiri utuh dan sepertinya penduduk munich harus tinggal pengungsian.

Pump control and valves 2

Bud (the senior instrument engineer) and Bob (the new instrument engineer) were on the trip to automate the start-up of the new  water injection pump. They caught people's attention because they were wearing coverall clothes and carrying their hardhats on their way from the hotel to the plant. 

Bob: Wow, Bud, I wonder what would happen on this start-up. I think it would be great since the simulations you did showed the stuff would work just fine.

Bud: Bob, anything can go wrong in the start-up. There is plenty that can go wrong with this system. The new control system must control the new water injection pump because the existing 2x100% water injection pumps only have design flow rate if 30,000 BWPD. but the actual produced water flows in excess of the 60,000 BWPD. So we need a third one and the pumps will be operated 3x50%. There is a level controller of the of the produced water vessel to control  a downstream control valve . Valve travel would have effect on the flowrate, This could result erratic control with poor stability and accuracy.

Pump controls and valves

The vice president of the company Mr Big boss just came to his plant for site visit and watch the plant performances and production personally.  The plant manager asked Bud (the instrument engineer) to escort Mr Big boss around the factory with him. The Big boss saw one of the pump operated and asked the plant manager what is it

Big boss: What is this thing called? This stuff is make a lot of noise and vibration.

Plant manager: This is pump boss. Pumps are used in the production facilities to move liquid from a low pressure/elevation to one of higher pressure or elevation.

Big boss: How this thing works?
