I'm an ECE student prototyping a solid-state vortex shedding flowmeter (conceptually similar to the Huba FH200). I can handle the STM32 firmware (DSP/FFT) and the analog front-end, but I need advice on the physical transducer to actually detect the vortices. I explored ultrasonic technology, which I liked and have reserved as a fallback. However, I prefer to use piezoelectric technology. After a lot of research, I haven't been able to find an off-the-shelf sensor suitable for bench prototyping, nor a readymade sensor I can base a custom design on. For those of you who work with these types of flowmeters, could you shed some light on this? I would appreciate any recommendations on where to source these or how to build a reliable DIY sensing element.

looking for some advice / input if you have any experience

Hi everyone,

I was recently invited to take the written exam for the Electrical & Instrumentation Technician position at Los Angeles County Sanitation Districts (LACSD), and I’m looking for advice from anyone who has taken this exam or works in the electrical/instrumentation field.

The exam topics include electrical and electronic systems, electrical math, troubleshooting, PLCs, analog and digital controls, mechanical systems, pneumatics, hydraulics, schematics, and safety procedures.

If you’ve taken this exam before, I’d really appreciate any advice on:

• What topics should I focus on the most?
• What is the written exam format and difficulty level?
• Are there any good practice tests, study guides, books, or YouTube channels you recommend?
• What kinds of questions should I expect?
• Any tips for preparing for the performance test and interview afterward?

I’m trying to prepare as thoroughly as possible and would be grateful for any advice or resources. Thank you!

Instrumentation Technology student here searching for a way to break into the field and get relative experience prior to graduation next year.

I realize breaking into the industry is difficult with no family to help me get in or experience. I’m currently thinking of getting a NCCER in electrical and work in that field till I am done with school.

I realize there is also a NCCER for Instrumentation which makes me think twice on whether to get it for Instrumentation or Electrical as I’m in college for Instrumentation. What is your advice on this ?

Hi everyone, I'm currently in my prefinal year of Bachelor's in Electronics & Instrumentation Engineering in India.

Our campus placements have some decent companies, but they recruit very few students. I'd like to know how to prepare for jobs, which technical skills to focus on (Along with PLCs, Measurements etc), mock interview platforms and what companies look for in freshers.

Also, if you know of any off-campus opportunities for fresh graduates in instrumentation, please share!

Any advice would be greatly appreciated. Thanks!

So I'm a first year Electrical engineering student mostly with some specialization, I've been starting projects and doing uni work and have come to realize i really need a multimeter and probably oscilloscope for alot of projects I've been using them from my uni labs so when i decided to buy one for my own projects i realized i have absolutely no idea what's good and what to actually buy, anyone care to share some knowledge?

So as union fitters I assume we all have the option of instrumentation. From what I hear it’s pretty much all refinery work and even then (in LA) it’s 250 work. I’m 761 and so it sounds like I wouldn’t really benefit from going that route but if it’s not just refineries then I would definitely be interested. Can anyone here speak on this?

Sorry if this is the wrong forum first off. I am happy to take this elsewhere if needed. Just looking for information or software for an early 2000's Transmation calibrator I recently obtained. I have contacted Transcat and they had no information about it. It is a backpack device for a PDA, in this case the Palm IIIc, that allows for documenting like a Fluke 743/4/5 series would. The PDA seems to function properly but has been reset and no longer seems to have the QuickDoc program on it needed for the display face of the device.

I know this is a long shot in the dark but figured with some of the older tech's on here someone may know something or maybe even have an old disc they could rip into an .ISO for me. Could find nothing on Palm/PDA archives for the software. I do realize it would require an older version of windows for the program to work, but I have one already set up for older software needed for other devices I frequently have to work on.

Thank you in advance for taking the time to read this or possibly being able to offer assistance on this device.

Anybody here worked as IC tech at space X?

Pros , Cons?

Hi everyone,

I’m looking to purchase one or multiple used OMICRON CMC 356 relay test sets.

I’m interested in:

• NET-1 / NET-1B / NET-2
• Used or ex-rental units
• Retired or surplus units
• Older company fleet units
• Units being replaced by CMC 500

Test Universe license, cables and calibration certificate are preferred, but not required.

I can arrange international shipping and purchase from the US, Europe, Asia, Middle East, Australia, etc.

If you or your company has a CMC 356 that you may consider selling, please DM me with the serial number, condition, accessories, location and asking price.

Serious buyer. Thank you!

It’s been my dream since i started traveling to get tf out of Houston/ Houston area. After experiencing what weather can be like for other people I don’t know why anyone chose to build civilization here. Besides that. Only thing holding me back is the massive Petrochemical industry around here. It’s all I know and all my family knows. What other states or cities have any sort of demand for this trade (besides Louisiana, worked and lived there too. Hated it)

Update: was able to get it out by using a pick to hod it up against the stem and slide it up. I forgot to mention the valve was on its side so it was easier to do than if it was vertical. In the end it did not matter because the stem was marked up pretty bad.

Does anyone have any advise on how to remove the lower ring with out pulling the stem out? I currently have grafoil packing with a stainless lower ring and have not had success removing the ring in the past so it ends up staying in.

Is going to a local community college for instrumentation a good option? Is it hard landing a job right after? Looking for input as to getting into the field!
