Let’s scale out a Coriolis flow meter with Endress+Hauser’s Applicator!
If we say nothing else in the articles we post on Visaya, we always tell you to scale out a device before you choose it. Why? Because you’ll probably regret choosing by brand or features.
Of course, you might say that you usually choose Brand X because it always works for you. But that doesn’t guarantee that Brand X can cover all your needs, especially if they change. Or you might pay more for sparkly features that catch your eye but do nothing for your process. If you can afford it, then knock yourself out. Otherwise, you should shop around for at least three good options, scale them out with your specs, and see which fits your process and wallet best.
I’ll bet some of you have never scaled out a device by yourself. Or maybe you have, but only in one particular way. So here I am to show you how to use a nifty online tool that doesn’t cost you a cent! Yep, we’re starting another journey today, teaching you how to scale out any field device.
But we need to start somewhere, right? I picked this tool because the company just updated it, so we’ll also see if the update improved anything. Now let’s scale out a Coriolis flow meter using the Applicator from Endress+Hauser. I got some nice real-world process data from a friend of mine – thanks, Rafael Silva! – to help us out here. Ready? Come on, this’ll be fun!
Naturally, you should use your own process data here. But since I don’t have a process that needs a device at the moment, my pal Rafael sent me some numbers from a metal company for gas flow measurement.
Just so you know, I’ll list only the basics that we need to perform this test. Usually, you’ll have a much more detailed list with sensor characteristics, electric parts, communication, and so on. But for now, let’s keep it simple.
- Product: gas
- Flow range: 500 to 3500 kilograms per hour
- Operation pressure: 5 bar
- Pressure range: 3 to 8 bar
- Nominal temperature: 25 degrees Celsius
- Temperature range: 20 t0 35 degrees Celsius
- Density: 1.2 kilograms per cubic meter
- Accuracy: +-0.3 percent
Now that we have our data ready, we need to access the tool. For that, we need to go to the Applicator on the Endress+Hauser website. You can start from the home page of the site if you want, but you’ll lose a lot of time because the E+H site kinda sucks. Just click the first link up there. If you’re not on Visaya when you decide to do your testing, then Google “Applicator Endress+Hauser.” You’ll get to it faster than if you poked around the site.
On the Applicator, first click on the three bars next to “Home” to pop open the main menu. Then click “Settings” and “Sizing Flow” to get to the basic configurator.
If you want more options and data about the applicator and device, then you need to change the “Basic functions” setup. In this case, we’ll go with the defaults, but next time we can select others. In the “Advanced functions” section, pick the “measured error at very low velocity” option, then scroll down and click the “Save as Defaults” button, the pinkish-red one. Magenta? Maroon? I’m not good with fancy colors.
You can scroll back up to the “General” option if you want to fool around with dates and units, or “Printing” if you need to tweak some margins or whatever. When you’re done, click “Home” to see the home page again. It gives you a lot of options, but we only need “Product Sizing.” Click “Flow” and let’s start scaling!
Let’s go step by step on this. When the Sizing Flow page opens, you’ll see “General parameters,” where you’ll fill in your process data. This first part is super important.
Basically, we need to know which flow meter from Endress+Hauser we want to scale out. Never mind the huge list of options; we’re focusing on the Coriolis flow meter, and we’ll pick a simple one for starters. If you don’t know the sensors or transmitters you need, then you can find the right device another way, but we’ll cover that in another article.
- Measuring task: Here you’ll choose the primary purpose of the flow measurement in your application, such as custody transfer or filling. We’ll stick with Monitoring/Control.
- Fluid: For this, you pick the product to measure. This menu is larger than it looks, because each option has a submenu. If you don’t know exactly what you have, then you can choose a dummy option, but you should try to make this as accurate as possible. Once you choose, the “Properties” button will appear. Click on that to add more details about the product or create a new product based on your information.
- Principle/Sensor: Choose the principle to use. Depending on the fluid you chose, the software may have already eliminated the options that won’t work for you. Nice touch! But you’ll need to choose the sensor as well. Foo. Anyway, we’ll go with the Promass E.
- Transmitter: This option will appear when you select the sensor. We’ll pick the 300 for now.
- TAG: Here you put in the TAG of the meter, which means the identification code of the device.
Now that we have this section filled in, time to add the process data!
Process data – Applicator
- Requested flow: Start with the units, then fill in the minimum, nominal, and maximum flow range.
- Pressure: Just put the operation pressure here; later, we can fill in the range.
- Temperature: Same here; add the operation temperature, and we’ll do the range later.
- Density/Density normal/Density standard: If you input the operation density, then the tool should calculate the density normal and density standard for you. You can change them afterward by scrolling back up and clicking the gear icon next to the Sizing tab.
- Molar mass: You can change the molar mass if you want, but it usually fills automatically, too.
- Viscosity: You can plug in the viscosity here or just go with the pre-populated number. Bonus – the “i” has some good deets about Newtonian liquids, shear thinning liquids, and dilatant liquids, if you want to read up on those.
- Pressure (min/max): Here you can set the pressure range, like I mentioned earlier.
- Temperature (min/max): Same here, only for temperature.
- Sound velocity: Sound velocity yay! If you have this information, then drop it in here.
Now that you’ve done all that, it’s time to pick the sensor and pipe!
Sensor and pipe
- Material (Sensor): Here you’ll see the materials available for the sensor you choose.
- Standard/pipe shape: Pick the connection standard and the pipe shape if necessary. The list should show only the options available for the flow meter you chose.
- Process connection: The Applicator will populate this field for you. Clicking the “Pressure rating” button displays a graphic that can depict the operation range or the requested range.
Other devices may have more options than we see now. The “Meter operating range” section shows you the minimum and maximum operating range of the meter you chose in the unit you chose.
Now that you have everything put in, you can get the calculated results, where you’ll find out the performance of your process meter.
- Requested flow: You set this range earlier, so the software just pulled the numbers from those fields.
- Flow velocity: The flow velocity will depend on the principle you chose. For Coriolis flow meters, the free cross section before the measuring tube affects the flow velocity. Click the tiny “i” to learn more.
- Flow velocity maximum: This field shows the maximum velocity allowed for the sensor. We’ll use these values to calculate the pressure loss and Reynolds number.
- Pressure loss: Here you have the pressure drop caused by the measuring tube. You can change the unit, if you want.
- Measured error mass: Ding ding ding! This data will tell you the performance of the flow meter in your application.
- Reynolds number: The Reynolds number will tell you if the flow is laminar or turbulent.
- Meter size: This field shows you the best meter size based on the provided information, but you can change it to see the performance of smaller or bigger meters. You can also click “Compare” to see different sizes and their performance numbers.
Scroll all the way back up to the “Chart” tab to get a graphic of the measured error mass or the pressure loss in the requested range or operating range. Beyond that, you have a table with the flow rate and pressure loss for the entire measuring range. If you click on the “Extended order code” tab, you’ll get more about the flow meter order code. If your scale out has any problems, then you’ll see warnings or messages in green or red. Read those for important info that may affect your process.
The Promass E 300 provided an error higher than requested, 1.4 percent in the minimum and 0.75 in the nominal and maximum. So you can change the sensor and transmitter to PROMASS F 300 and check the performance. The Promass F 300 has an error of 0.7 percent minimum and 0.35 nominal and maximum! You can also change the measuring tube size and so on.
If you can get by on the error margin of the Promass E, then you’ll save money over the Promass F. You have to decide what your application really needs. You can try different principles and check the performance on those as well.
At the bottom, you can print out everything or select only certain sections of the information you want. I suggest you print the following:
- Fluid properties
- Compare sensors
- Warnings and messages
Next, you can go to the configurator to find the entire order code of the flow meter. Or just add it to the shop basket if you want to buy it online.
I couldn’t figure out how to compare sensors in the online Applicator. You may only get that option if you install the software. Basically, you can compare the performance of different models and principles against each other in your application.
