Laminar flow element; a critical element. The Laminar Flow Element as seen in Picture 1 is a critical component of the thermal mass flow meter based on the bypass principle.The functionality of the Laminar Flow Element (LFE) is to create a shunt. These elements only work with their respective flow types. If a flow uses a different flow type, there’s no way to roll back that flow’s transaction on a fault path. When working with a flow that’s not a screen or record-triggered flow, evaluate each element to determine whether fault paths are right for that element in that flow.

Is encountered.To move the content into a page region, the element needs to be removed from the normal document flow position with the running() function of the position property, and inserted into the specified region with the element() function of the content property.CSS @page { @top { content: element(header) } } h1 { position: running(header) }The @page rule specifies that the top page region is a new running header named "header".The rule for the h1 element moves it to the "header" running element, removing it from the default normal flow.Prince also provides another interface for creating running headers: the content can be removed from the normal flow with prince-flow: static(), to be placed in a page region with content: flow().CSS @page { @bottom { content: flow(footer) } } footer { prince-flow: static(footer, start) }In addition to the standard mechanism, the Prince specific one offers an extra feature that might be useful in certain scenarios: the static() function accepts an optional start argument, which makes the fetched content available, as if it were fetched from the start of the document. An example to clarify:Many HTML documents designed for browsers have the following structure: header> main content footer>Unfortunately, if you want to place the footer element in the page footer, it will only appear on the last page - because it is at the end of the document! To solve this, the document must be modified to look like this: header> footer> main contentIt can be achieved by using JavaScript to move the element, but the simple start keyword on the prince-flow property instructs Prince to pretend that the element was seen at the beginning of the document.The element() and flow() functions replace the entire margin box, and cannot be combined with other content. If you just want to capture some text from the document, use named strings instead (see Copying content from the document) - they can be combined with other content.Selecting pagesIt is often necessary to apply styles to some pages, but not others. Either applying them to only some pages, or on every page except selected pages. CSS and

What is a Flow Element? Types, Comparison of Flow Elements

Set to “Multiple,” the screen component becomes available for selection later on in the flow and has a “selectedRows” collection variable within it that contains only the records that were selected from the table.The strange thing about this collection is that if no records were selected, it still isn’t considered empty by Decision elements but is detected as still containing brackets. However, the data table also has a “firstSelectedRow” record variable inside that contains the values of the first selected row, which can be used to check if any records were selected by checking its Id field. So, the first thing we do next is create a Decision element to check if any email list rows were selected to be added as subscriptions. We do this by checking if the firstSelectedRow.Id field from the data table is null. If it’s not, then at least one Email list was selected. We then create a Loop element on the ‘Yes’ side of the Decision element loop through the records in that “selectedRows” collection. Then, we create a Record Data Type flow variable to hold the values of each Email Subscription we need to create, and a collection variable of the same type to hold them all. Next, we create two Assignment variables inside the loop: One, to set the values for the records we need to create (we set the contact Id from the contact record we got in the first Get element, the Email List Id from the current item in the loop, and the Name field as the name of the current Email List in the loop)The other, to add the variable to the collection we plan to create the records from. We then use a Get element to create the new Email Subscriptions in the collection.This part of the flow now looks like this: Only one part left to go: the removal of subscriptions the Contact no longer wants. We start with a Decision element to check if any items were selected from the second data table of the second screen. Then, we add a Delete element to the. Laminar flow element; a critical element.

Laminar Flow Element (LFE), a Critical Element for Flow Meters

Our flow:Next, we create a second Get element to retrieve all of the Email Subscription records currently related to the Contact record:Then, we create a Decision element to check if any Email Subscriptions were found in the previous Get element. We will use the result of this decision later in the flow. Now, our flow looks like this–all of which happens before the first screen in our flow loads:From here, we can finally make our first screen element! We want to create the screen at the very bottom of the flow after both sides of the decision. Before we do that, we clean up the screen, starting with hiding the header and pause button and giving the next/finish button a custom name. Then, we add two Section components, each with their visibility based on the result of the previous Decision element. The idea here is to show one section if the Contact is already subscribed to one or more Email Lists and another section if they are not. An alternate method of doing this would be to create two screens, one on either path of the Decision element—but my preference is to have as few screens as possible since it makes it much easier to manage changes and see that the screens are consistent across the Screen Flow. We will then add a Display Text component to each of the Section components, and a Data Table (currently in Beta) to the section that is displayed when there are existing Email Subscriptions. We also add a Display Text component below both Section components to display at all times. When configuring the Data Table, select the Email Subscription collection from our previous Get element and add the Email Subscription Name and Created Date fields as columns to be displayed. Next, set the Row Selection Mode to “View only” because we don’t need the user to select anything yet. I’ve also renamed the columns to “Subscription” and “Date Subscribed” respectively. Debugging the flow for a contact with no current Email Subscription records would look like this:Debugging the flow for a contact with multiple

Requires 80 times inner pipe diameter of straight pipe run – although 20‑30 times is the most common requirement.If the required straight pipe run is not available, a flow straightener can be used. Different types are available each with their own advantages and disadvantages. The most common is the “Bundle of Tubes” which usually consists of 19 tubes fastened together and to the main pipe. The length of the tubes depends on D ‑ the inner diameter of the pipe. The inner roughness of the pipe has to be small in order to not influence the flow profile. This consideration is mainly necessary in the smaller sizes. Additional considerations for installation include:Installation of a primary element must be as far away as possible from any pulsation.For liquid flow measurement, the liquid shall run full in the pipe.The connecting tubes between the pressure tubes and the differential pressure transmitter shall always be mounted with a fall.In air and gas flow measuring, the best place to mount the transmitter is above the primary element allowing any condensation to run backwards into the main pipe. In liquid flow measuring, it is best to mount the transmitter below the primary element enabling any air or gas to escape into the main pipe. Finally, for steam flow measuring it is recommended to use condensing chambers placed in the same horizontal height. The differential pressure transmitter is mounted below the primary element. The condensing chambers should be half filled with water. The pressure of the water

To exclude, we are ready to retrieve our Email Lists! To do this, we create a Get element at the bottom of the flow with various criteria. In this example, I only want to select Email Lists with the “Active” checkbox field checked. We also want the Id of the records we retrieve to not be in the collection we just created, so we will use the (newly released and very exciting!) “Not In” operator to do so:We will also create a Decision element to check if we did retrieve any email lists just like the one we previously created, so now our flow looks like this:Now we are ready for our second Screen element!Just like our first Screen element, we start by adding two Section components. The first section will be visible based on our second Decision element for finding Email Lists and allow the user to select the Email Lists to subscribe the contact to. The second will be visible based on the first Decision element for the contact having one or more existing Email Subscriptions and allow the user to select the Email Lists to unsubscribe the contact from.We then put a Display Text and Data Table component into each section. The first data table uses the collection of Email Lists from our third Get element, and the second uses the collection of current Email Subscriptions from our second Get element. I set the first data table’s columns as the Email List record Name and Description fields, and the second data table’s columns as formula fields on the Email Subscription record that hold the Name and Description field values from the related Email List. When we debug the flow using a Contact record with two current subscriptions and one other Email List in the system, our new screen looks like this:Now that we have our two screen flows, all that remains is to create the logic and actions for updating subscription types specified by the user.Before doing that, it’s helpful to understand how the table components work. When the “Row Selection Mode” for the data table is. Laminar flow element; a critical element.
