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).

Don't let this great middle grade book escape you.
Format: Paperback
I am an Anglophile and love the history of England. This book was an incredible read and fed my addiction fully with Renaissance England inspired history and fiction featuring Ben, a 15 year of commoner and an accidental hero who finds himself a prison let working the Tower’s dreadful jail. This spry has short chapters that will appeal to children with a short attention span, and the storyline like the other installment feature children using real life problem solving skills as they help others. This is an overall great read and highly recommended.

Suspenseful
Format: Kindle
Ben a 15-year-old found himself chained to a wall in a dungeon. His job was to carry coal around the towners to rich prisoners. Princess Elizabeth was thrown into the traitor's tower by her evil sister Queen Mary. He had to try and help save her, now he is a prisoner. The adventure starts, will Ben get out? How will he ever get out? will the princess be saved? Every page is filled with suspense. I loved the history lesson at the end of the book, filled with so much information.

A Tudor Tale of Derring-Do for Children
Format: Kindle
Ben Forrester sees a young woman being dragged into the Tower of London and despite the good advice of his friend, Tim and it being a seemingly impossible task, he sets out to rescue her. On the way, there are messages written in invisible ink, a princess dressed as a coal boy - a coal boy dressed as a princess - dungeons with rats and a lot of adventure. This is an exciting and well-written tale for children, set in the reign of Mary Tudor in the violent and cruel days of the sixteenth century. It has a lot in it to acquaint a reader with life and society at the time and gives a (highly distorted) sketch of the political events of the time. My one big complaint as a historian is the biased perspective of this book which reinforces many popular myths and misconceptions about both Mary and Elizabeth. As this book might be the first (and for some children maybe the only) experience they have of the period it seems to me tragic that it does so. To read it you would think Elizabeth was perfect and Mary pure evil. We are told of Mary's burnings but not why they happened or of Elizabeth's subsequent persecutions and none of it is placed in context. This is a black and white version of history which is horribly inaccurate because it is so, and misleads another generation to despise the woman who was England's first true Queen and who overcame so many challenges including those of politics, religion and rabid misogyny to rule in her own right. I love the irony that we find out in the historical notes at the back that the story of Ben's escape was based on the real-life escape of a man imprisoned there by Elizabeth on account of his beliefs... So whilst I can applaud this as a good, immersive, book to help a child learn about the social history of the time, I would hesitate to recommend it because of the way it reinforces the ignorant bias of popular history over the truth.
