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).

Better transfer, less content.
Transfer of this BluRay edition of Doinel's box is of course better (however, the difference is not dramatic) than in previous DVD box of the same cycle by Criterion. However, the book included has not even half of the texts from DVD edition. There is also less extra materials at discs. Thus, at some points this BluRay edition is worse than DVD's. I don't understand why Criterion made this box poorer in content than the box in poorer quality of the picture.

Great films, but quite flimsy box set
I would give it 4/5 if Criterion had made it more sturdy. It arrived in a plastic bag and was all beaten up. (Only Amazon could screw up a shipment this badly.) The short film "Les Mistons" has major gamma issues, which takes away one star.

Great transfer of a classic set -- except borked Les mistons
A really nice set of one of French cinema's greatest "franchises" -- though we did not call them that back then. The tone shifts after the 400 blows of course. But it sort of makes sense, too, as things change for the character as well. But beware, Criterion failed to grade the Les mistons short film correctly. Looks a lot like HDR/SDR gamma was switched or something similar. You can see it from the opening studio logo and credits which are not the right color. Hopefully they will issue a fix. Until then you may want to wait.

Some of Truffaut's greatest works... and they're wonderful
A reviewer here called these a "waste of time" and "weird movies," giving the set 1 star. Sorry, pal, maybe critically acclaimed films by one of France's--or the world's--most important filmmakers isn't your thing. Nothing "weird" about these very accessible, realistic movies about human beings and life. Truffaut did with this series over a course of 20 years what Richard Linklater did in one movie ("Boyhood")... but between 1959 - 1979, Truffaut's attempt was more ambitious, daring, and envelope-pushing. Lead actor Jean-Pierre Leaud goes from a 14 year old to a guy in his 30s, and he's wonderful in every episode. Each film is touching, funny, dramatic, and worth seeing for anyone interested in world cinema. "The 400 Blows" is Truffaut's debut feature, and what a great one it is. It's more serious than the others in this series, and is likely the most lauded. "Antoine & Colette" is a short film made 2-3 years later. "Stolen Kisses" gets more into comedy and it's a delight. "Bed and Board" continues where the previous one left off. "Love on the Run" is decidedly the weakest but is still enjoyable. Truffaut died too young five years after that one was made. One wonders if he and Leaud might have made another entry in the late 80s or even the 90s. Great stuff.

What a Fantastic Release on 4k/BD by Criterion!
I have enjoyed my DVD set of these great Truffaut for years, and am so happy to see this 4K set about to be released. Will be ordering this and looking forward to it. There are copious extras, a booklet, and the full set of Doinel films, including Antoine and Colette. The first film in the series, THE 400 BLOWS, is considered one of the greatest films of French cinema, and of the Nouvelle Vague (New Wave). It's by turns entertaining, funny, thought-provoking, and heartbreaking. That movie and BED AND BOARD, a domestic comedy that is truly funny, are my favorites. But all the movies here are worth seeing and owning. Criterion rocks.
