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).

It's rare to see this kind of representation in a book for tweens, and I am 100% here for it!
Format: Hardcover
My 9-year-old daughter loved this book. It's about two 6th grade witches (Delpha and Katybird) from rival Appalachian families who are learning how to use their magic. The book is told from both of their points of view. As a parent, I was pleasantly surprised by the different types of representation in this book and how sensitively they are handled. Delpha's dad left her and her mom when Delpha was little, and they now live in poverty. Delpha's mom is struggling to pay the bills and sells her family heirlooms to Katybird's grandparents, who run a small museum. Katybird is intersex (androgen sensitive) and believes this is messing with her magical powers. Katy's brother Caleb is Deaf and communicates with sign language. Another character, Tyler, has two moms. It's super rare to see this kind of representation in a book for tweens, and I am 100% here for it. There's a great scene where Katy reflects on attending another girl's "first moon party" and the attendees share stories about getting their first periods. When the other girls hear that Katy will never have a period due to her androgen sensitivity, they are shocked and treat her with pity and say they will pray for her. Katy is upset because she already loves and accepts herself. "As if making babies was the whole point of me existing," she thinks to herself. I seriously loved this example of how well-intentioned behavior can be hurtful. I also liked how characters getting their first periods is treated as something magical and worthy of celebration. There is so much about this book that is like a breath of magical fresh air. In addition to all the beautiful inclusive elements woven into this book, it's just really FUN. There is a pet raccoon, an enchanted outhouse, zombies, and hexes that go wrong. The only minor complaint my daughter had was that the plot relies repeatedly on the two main characters being separated and looking for each other. Otherwise, this book was a winner with our young reader. Write more books, Ash Van Waterloo! We love you!

Emotional development...
Format: Hardcover
Cattywampus Ash Van Otterloo This is the story of Delpha McGill, a girl that doesn’t like rules or keeping secrets. Delpha lives in a small town in rural Appalachia, Howler’s Hollow, where magic is not permitted. She discovers her grandmother’s hidden book of spells which she is determined to use to help her mother. Katybird Hearn has her own reasons for wanting to get her hands on the book of spells and has resolved nobody is going to stand in her way. She comes from a long line of witches. In the midst of their squabble, they unintentionally allow a curse to escape. The curse is so evil it wakes their dead ancestors, the Hearns and the McGills, The two girls must learn to work together if they are going to save the town from the zombies. The author uses great sensitivity in incorporating androgen insensitivity in the plot. Androgen insensitivity syndrome is a condition that affects sexual development before birth and during puberty. People with this condition are genetically male, with one X chromosome and one Y chromosome in each cell. Because their bodies are unable to respond to certain male sex hormones (called androgens), they may have mostly female external sex characteristics or signs of both male and female sexual development. Poverty, sorcery, fears, friendship, and ignorant biases are all a part of this book. Author Ash Van Otterloo portrays life in a southern country town in the mountains and he does so without being demeaning or patronizing. The characters are well fleshed out. While magic is part of the plot, it is merely a means to showcase the emotional development of the two girls. This is a fast-paced read. The target audience is 10-13 years of age.

Fun if a bit offbeat upper elementary fantasy
Format: Hardcover
I read this in one afternoon and have to say I enjoyed it. The cast of characters are incredibly diverse, and for the most part this is a believable story (despite the undead magicians and ridiculous outhouse) This story is a "Hatfields vs McCoys" if the two hillbilly families were magicians and were feuding over how they practice instead of over moonshine and land. This brings me to my first gripe with the novel. The dense dialogue in accents. For a middle grade book, the text is filled with a lot of phonetic spellings and backwards english. I guess it is to be atmospheric, but it just makes the characters seem dumb. And that is sad because they are not. Stubborn, and sometimes too preoccupied to see what is under their noses but not stupid. I sometimes felt that the characters had been written into a corner so there were multiple instances of "because magic" and convenient acts of random fortuitous "we have everything we need and don't have to search more because the Luck Gods were smiling". Once or twice I completely missed how the characters got from point A to point B and I Really dislike "wave a wand and everything is good and the mortals forget what happened". A little convenient magic written to solve a solution is fine. But the ending sort of feels a little flat when a Major concern for the entire novel is resolved by sleight of hand. On the whole though, the characters are likable, and age appropriate (though a bit whiny at times for this parent ;-p) and I liked that diversity isn't a "cause" its just an adjective...As in, there is a gay couple who act like every other parent in the story. There is a deaf younger brother who isn't treated as 'precious' but as a functioning human. Even one of the main characters is intersex and does question "Am I girl enough to be a witch". None of the cast of characters feels forced or out of place making this a nice addition to my kid's library. ARC free in exchange for an honest review.
