More information in less space.       

It is amazing how sometimes similar applications can come back to back….Last week's blog came from a customer asking how to measure the main power grid frequency. And later the same week  I had a totally different customer ask me about how he could display upper, lower and current value of the main electrical grid frequency in groov. What are the chances of that!!??

This customer wanted one gadget to display all three values. Why so dense? Because they only use groov on smart phones, no PCs or Tablets. He was polling the data from a bank of UPSes and so needed to display a lot of data. Screen real estate is prime on those devices. What can we do to help?

In this week's blog, we are going to have some adventures in Z-Order.

50 or 60 Hertz - Roughly.

Measure the main power grid frequency, he said. It will be fun, he said…. Actually, pretty sure I said something like, “it will be easy”... and I was mostly right, and best of all, it did turn out to be fun!

It seemed like both a reasonable and easy request. The requirements were to measure the mains power grid frequency to a resolution of 0.01 Hertz, and to do it every 125 milliseconds (roughly; it could be a max of 200 milliseconds, but not much longer).

Why? In this case, the chase is better than the catch. It's enough to say the customer had his reasons, and this blog is about the chase.

We rely on our smartphones so much now. It's hard to remember when I couldn't instantly:

• find out the traffic between here and where I'm headed
• message my friend to say I'll be late
• take a photo of anything and send it or upload it
• see how many steps I've taken today
• check stocks and the news and the weather
• listen to music/make music/watch a video/play a game
• summon a car or order lunch or...

So seriously, why would I want that convenience to stop with my personal life? 

What I'd like is to also see status and data from equipment and systems I'm responsible for, and especially to be notified if something's out of line.

Do you monitor temperatures?

A lot of control engineers do, especially in fields like water treatment, refrigeration, thermoforming, refining, food processing, and energy or building management.

There are a variety of temperature sensors on the market—ICTDs, thermocouples, RTDs, thermistors, infrared sensors. Accuracy, cost, wiring complexity, and environmental conditions are some of the factors that determine which one is best for your application.

Nothing like a cold shower to get you moving:

Most of us never give any thought to our hot water service pilot flame. But when it goes out...cold shower first thing in the morning, anyone?

Bleh.

The first time it happened, I simply re-lit the pilot and showered with cold water. After the third cold shower, I knew it was time to be a little more proactive!

Get a mop, I spilt some electricity:

The past few blogs we have talked about visualizing water usage in groov and how it not only helped me save water, but also highlighted the fact that I was not seeing all the water use I thought I was.

Electricity is a bit different from most other things. Spill water on the floor and it's pretty obvious; spill electricity and often no one is the wiser.

Was I seeing all the power use in my house? Are there any so-called phantom loads (sometimes called vampire loads) sucking or sipping power that I did not know about?

Monitoring the water mains:

As mentioned in my blog last week, it was not until I monitored my water usage that I found out I was not monitoring ALL of my water usage.

My whole house water meter was just that, the whole house. It did not show any of the garden/lawn water use.

Let's talk about how we might get that data and what it could mean for conserving water in all aspects of our lives.

Every application is different. But some things are similar:

• You have to monitor and control equipment.
• You don't have enough time in your workday.
• Your budget is seldom enough for what you have to do.

Watch the video and see how groov can help you save time and money in facility management. A groov mobile interface lets you keep moving while you monitor systems and equipment.

If your building automation system uses BACnet—and many do—you can integrate it with your SNAP PAC System using our free BACnet Integration Kit for PAC Project.

We've just updated this integration kit to include:

Older wind farms still produce clean energy, but many weren't built for modern monitoring and control.

This lack of remote visibility causes problems for utility companies and other owners, who must immediately respond when regulators call for changes in production.

That's because the electrical grid has to be a Goldilocks kind of system: not too much electricity, not too little. It has to be just right.
