Hi, guys. My name is Nick Smith. Thank you for joining this episode of Connect. Today, we have a really cool hands-on demo of a mechanical flow metering solution. We have Javier Ramos here from our low power RF team joining us. How's it going, Javier?

Good.

Cool. So before we dive into the actual demo, can you tell me at a high level a little about flow metering and flow metering solutions?

So usually, when you hear flow metering, we're talking about gas, water, or heat flow. And in those applications we see a lot of metrology across the board, like ultrasonic.

Today, we're going to be focusing more on impeller-based metrology, which is a rotating disk that is being rotated by the flow of water or gas. And we are able to monitor the rate of this change to calculate the flow of the water and gas.

OK. Yeah, that makes sense. And so for the wireless piece, what kind of wireless standards or technologies are we seeing being used in these flow metering solutions?

So yeah. In flow meter application, in most cases, these need to be battery operated. Therefore Sub-1 is usually the ideal solution that could provide low power.

OK. So for TI's Sub-1 solution that's available, what kind of key elements allow to get the low power needed for these solutions?

So yeah, in CC1310, we have three main blocks. We have the M3 core and the RF and the sensor controller. The sensor controller core is what's going to be interacting with the actual sensors, the LC circuit that we have here in this application. While the M3 and the RF are sleeping.

So the sensor controller can monitor this flow meter solution while the rest of the device is sleeping, allowing for very low power consumption. Is that correct?

Yes.

Cool. Well, can you show me what I'm looking at here, tell me a little about the setup. So yeah. So we have this board right that's powering up this disk to kind of mimic the flow of water and gas. And then we have the CC1310 LaunchPad. Then we have the LC sensitive sensors attached onto the top of it.

Measuring the flow of the disk--

Correct.

--and the rate. Well, let's fire it up. Show me what it can do. So this is mimicking water spinning the disk, right?

Correct.

And then what am I seeing over here?

So here on the far right, we're seeing the actual RPMs being calculated.

And then this is counting the--

The rotations.

OK. Cool so it's counting backwards, I guess, the number of rotations.

Yeah. So then if we go ahead and press the button, we can be able to spin it the other way and start counting the other direction.

So now it's counting up. And we can see the RPMs again. Cool. That makes sense. This is a very cool demo.

So if the folks watching want to learn a little bit more about this work, where can they find some references?

So yeah, if you're able to go to ti.com and look up the TIDA-01228, you'll be able to find this TI design on ti.com.

Perfect. Well, thanks guys. Thanks, Javier. Thanks everybody for joining this episode of Connect. Be sure to look up the TI design that Javier mentioned for more information. Or go to ti.com/simplelink for more information about our simple link solutions. Always remember you can tweet at me, @SensorToCloud with any questions or suggestions of news topics.

And thank you, guys. We hope to see you next time.
