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 sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head and displays them in plain text in the alarm menu. FCM measures the actual pressure and flow rate and eliminates the need for additional monitoring and control devices (accuracy of ± 1.5 % of the set value in a trouble-free process). The measured pressure and flow are displayed and can be integrated into the process control system, e.g. SCADA. In addition, the AutoFlowAdapt function automatically adjusts the pump speed to the process conditions to maintain the target flow even with fluctuating back pressure or air bubble formation (degassing drive strategy). 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,
  • A pressure sensor.

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:

  • The sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head.
  • Measurement of actual pressure and flow.
  • AutoFlowAdapt automatically adjusts the pump speed to the process conditions (what you set is what you get).
  • Degassing drive strategy in case of air bubbles detected in the dosing head and Auto Deaeration during pump standby avoids stand-still due to air-locking.
  • ConditionCheck analyses the pump and the system where the pump is installed.
  • 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.
  • Two-step key lock function to protect the pump against unauthorised access.
  • Multi-parameter dashboard function to provide further information on up to 4 parameters.
  • Counter for total dosed volume (resettable), operating hours, etc.
  • Save, copy and load customised settings as well as reload factory settings.

Signal inputs/outputs:

  • Input for pulse, analog 0/4-20mA, external stop.
  • Input for low-level and empty-tank signal.
  • Two potential-free output relays for max. 30 V AC/DC (configurable, e.g. alarm, stroke signal, pump dosing, timer etc.)
  • Output analog 0/4-20mA.
  • 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).

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.

LOVED THIS STORY!
Format: Kindle
I never wite reviews, but this book was too good for me to NOT give props and let others readers know it's such a good read. They need to make movies of this one and I can't wait until the next book comes out. The story building was so good and I loved that the main character wasn't a silly useless princess or something. Shes intelligent, strong, and loves her friends. The description of the characters is really good also and its such a good plot. Not your average paranormal romance novel of some princess or the girl working at a diner. LOL! I'm totally team Rykan for her! Fingers crossed for the next book and October 31st can't come soon enough.

Imperfect characters
Format: Kindle
4.5 stars ⭐ I don't really understand the harsh criticism in some of these reviews (Goodreads). I rarely write reviews myself, but I think this book deserves it. Look, it absolutely has its issues. I wasn't feeling it in the beginning -- the first few chapters were all tell and no show, literally just telling us all this background in a few paragraphs rather than feeding us bits and pieces at a time. The writing significantly improves after a few chapters, though. And I didn't catch any spelling or grammatical typos often found in new, self published books.  After the rough start, I absolutely flew through the rest of the book and couldn't put it down. Seriously stayed up until 2am with it. So I also don't agree with comments calling it boring. Definitely did not bore me. I thought it ticked all the right boxes: romance, fantasy, a magic system, tragedy, fate, character growth.  A lot of the poor reviews I'm seeing are in regards to the FMC's character. Personally, I like flawed characters and think it's more realistic than reading the POV of someone who always makes the right decisions, is always honest, is always selfless, etc. Humans aren't like that. Readers love when male leads are morally grey, but God forbid a woman isn't perfect.  So I like flawed characters and I like a little bit of tragedy, which the author provides. Ends on a cliffhanger, and I can't wait to read the sequel next month. I really want to learn more about Malachi.  All in all, not a bad start from this author. Give it a chance. SOMEWHAT SPOILERY: I LOVE the concept of fated mates that kind of hate each other. Most books with the fated mates trope allow the characters to immediately fall for each other and get together relatively easily. But this is way more interesting ;)

what just happened
Format: Kindle
I’m not gonna lie. This story had me from the beginning. It’s something about a girl running from an obsessive stalker that happens to be set in a fantasy realm. This story had everything you could want in a great plot. I mean intrigue, politics, betrayal, murder, witches, shades, fairies, shifter, etc. My heart grieved for Dahlia and everything she went through and honestly i don’t know who to root for in this story as all the males are morally gray which I love. All have a hint of evil. Book up this book and you won’t be disappointed. Soo ready for the next book.
