You’ll learn how to use your calculators for calculating immediate rates in this tutorial.

Need to automatically calculate a rate change based on your 2 previous measurements from your Industrial IoT sensors?

If so, then you’ve come to the right place.

You can use your rate calculators to calculate rates of anything, like water well flow meters, or rain water as you’ll see in the example here.

To get yourself started you’ll log in to your account and go to your Device Manager.

Click the name of your Industrial IoT device / sensor hub you want to configure for sensor rate calculations.

In this example you’re seeing sample IoT sensor data collected from sensor hubs connected to knob counters and tipping buckets like the Hobo RG2, which upload rain water measurements for data logging to

Once you’re seeing your device details page for your sensor hub, mouse on over to the orange Configure Data Path button and click Other Calculators from your drop down menu.

You’ll choose your calculator type using the drop down menu you see in the screenshot on this blog. Select your rate calculator that calculates rate using your most recent sensor data.

Give your new calculator a name and click the blue + / plus / addition button to create it.

You’ll see the IoT sensor calculator configuration window with your options for setting up your rate calculator.

Remember to check mark the box up top to enable your calculator after you’ve configured it.

The calculator name is up top and there is a Notes field where you can write some notes about why you’re making this calculator. This is helpful for you and your teams when someone is looking at this at a later date trying to make sense of it!

You’ll see in the screenshot that we made some notes about rain fall rate and water calculations from tipping buckets. Write yourself a nice note about what you’re calculating the rate of, whether it’s water well flow meters made by McCrometer, Foxboro Schneider ElectricEKM Metering, or any other Industrial IoT device sensor.

Choose your Output channel where your rate calculations will be saved. You’ll see we picked the User 04 sensor data column in the example screenshots.

Your input channel is what you want to calculate the rate of, whether it’s flow meters, rain, other water sensors, or anything else.

Your 1st calculation variable is the maximum age, or how old, how far back in time you want to go to find your previous sensor reading for your rate calculation. This immediate rate calculator calculates the rate of change based on your current sensor reading and the 1 previous to it. If the previous sensor measurement is older that the time you put here in variable 1, e.g., 60 seconds, then the rate will automatically be 0. Set this according to your remote monitoring scenario and how you need your rates calculated.

The 2nd calculation variable can be used to calculate your rate in different units. By default, calculates rates in milliseconds, but if you want your rates in seconds, put 1000 here, for minutes enter 60,000 and you’ll have your rates, e.g., flow rates in minutes like 314 gallons per minute / gpm.

Remember to check the box to enable your calculator up top, then save your calculator and you’re all done.

You’ll see your calculator results for each new sensor data measurement uploaded to by your sensor hub.

In the device details screenshot you see a tabular data view where the User 04 field has the results from our new calculator.

Your new calculator field has now permeated throughout your remote monitoring features.

You’ll see it on 2D & 3D maps, graphs, and other analytical features.

That’s your overview of the immediate rate calculator. Take a gander at our overview video of calculators that covers calibration, statistical analytics, filters, interpolation, conversions, and other calculations.

Perhaps you’ve already seen that there are many other helpful calculators we’ve implemented, as a direct result of requests by customers like you, to perform Industrial IoT sensor calculations like:


Questions? is an open Industrial IoT cloud platform, which means you can use sensor hardware made by just about any hardware manufacturer.

You integrate all of your favorite sensor hardware, and we’ve got the software covered with the experience and flexibility of

We can also make recommendations and help you decide based on our knowledge from years of experience in the field helping customers deploy remote monitoring systems in various industries.

Take a gander at our Customer Stories Page to see real world Industrial IoT use cases.

You’ll see IoT customer success stories about how helps organizations in various industries to improve business operations and save time and money.

How? By remotely monitoring valuable assets and things like water wells, piezometers, tanks, methane / CH4, bridges, noise / sound, and levees. And how combinations of hardware from a variety manufacturers (like Flowline, Senix, In-Situ, McCrometer, Clairair, Yoctopuce, and Geokon) make the most sense for your remote monitoring systems.
