The SMART Digital DDA-C is a compact positive-displacement diaphragm dosing pump with variable-speed drive (stepper motor) and intelligent control electronics with minimum energy consumption. The SMART Digital Dosing series operates at full stroke length to ensure optimum accuracy, priming and suction, even for high-viscosity or degassing liquids. Depending on the set capacity, the duration of the discharge stroke varies, ensuring an optimal, uniform and continuous discharge flow. The click-stop mounting plate allows installation in three different positions without using any additional accessories. The control cube can be easily turned to the front, left or right position. The click wheel and the multi-coloured backlit graphic plain-text LC display enable intuitive commissioning and operation. The control elements are protected by a transparent cover. The DDA-C has built-in connectivity that allows easy setup and tracking via the Grundfos GO app as well as easy integration into a Modbus RTU or TCP bus system. The dosing head includes the following parts:

  • A durable and chemically resistant full PTFE diaphragm,
  • Double ball valves for maximum dosing accuracy,
  • A deaeration valve for easy start-up.

Operation modes and functions:

  • Manual dosing in ml/h, I/h or gph.
  • Pulse control in ml/pulse (incl. memory function).
  • Analog control, 0/4-20 mA (scalable).
  • Pulse-based batch function in ml, l or gal.
  • Timer-based batch function (dosing timer cycle or week).
  • Fieldbus control (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).
  • Cloud control and monitoring (Smart Digital Chempairing Suite; Grundfos Connect).

Other features:

  • Auto deaeration during pump standby to avoid stand-still due to air-locking.
  • Two SlowMode steps (anti-cavitation), 50 % and 25 % maximum flow, e.g. for high-viscosity or degassing liquids.
  • Max. Capacity to limit the capacity of the pump to a set maximum.
  • Service information display to show when service and which wear-part order numbers are required.

Great beginner book but should have covered layout
Format: Kindle
I've done HTML and made an attempt to learn CSS before. This book is a GREAT choice for beginners as well as myself. The examples are pretty easy to follow and made sense. Most of all this was THE book on CSS I was looking for. My previous attempt to learn CSS was overly complicated and convoluted and left me completely confused on CSS and barely able to get the job done. Perhaps it was because it was for the specific software I was using rather than just CSS. Regardless, after this book I feel confident with CSS now and was surprised how easy it actually is when properly explained. My only complaint on this book is that I think it should have covered page layout with parent DIVs and child DIVs or page layout in general. That's definitely the next thing to learn after reading this book. But I was able to easily find a video on page layout after reading the book and took it to the next level. This book prepared me for that and got me to a place where I was ready for that. Hopefully the next version of the book will include page layout techniques to give your website a more professional look. I'm giving it 5 stars because page layout and graphic design really probably are intermediate topics. So, for an HTML and CSS book, this really "hit the spot"!

Easy to follow for a beginner!
Format: Paperback, Format: Paperback
It’s easy to follow and understand, like putting a puzzle together following step by step instructions eventually feeling more and more confident. You will learn how to build a website starting with HTML. Love the exercises and snippets. If you never used VS code text editor, I suggest watching video on social media about VScode editor if you use this book. VS is a great code editor and it’s free. Pro tip- install live preview from extensions from your explorer pane, it saves time refreshing a browser to see your work and refreshes in real time as you build and style your pages. The book will go into detail about more technical terms as you move through the chapters. I am a student in Front End Web development and everything internet. This book does a good job identifying some of the technical terms of how browsers display HTML documents in a viewport leading up to responsive design. This book is beginner friendly. I don’t think you need any knowledge of HTML, or CSS to start with this book. You don’t need to be an IT technician either, just a simple understanding of how the internet works. You do need to have an interest in learning to code though because it can be a learning curve. Persistence, patience, and lots of practice will make you successful and that’s the payoff. Buy with confidence!

A Solid Book & Place To Start!
Format: Paperback
So far I'm enjoing this book and I do recommend it for beginners and novice programmers alike. It's a sold read and an extremely solid place to start. I knocked off a star because it also does tend to be a little longer than needed.

Amazing book
Format: Paperback
One of the standout features of this book is its stunning design. Each page is meticulously crafted with vibrant colors, clear diagrams, and engaging layouts, making complex concepts easy to understand and visually appealing.

Whether you’re learning the basics of structuring web pages with HTML or delving into the intricacies of styling with CSS, the book provides clear explanations and practical examples every step of the way.
