Oval-gear PD meters overlay displacement; Coriolis already owns mass flow
The oval-gear chamber still is the positive-displacement SKU: displacement volume belongs on a Qwen Image 3 spec slide at 4cr / 2K, Coriolis meters already burned mass-flow overlay, and Veo digits on a PD register are a fake calibration.

An oval-gear listing that books is a photograph of this chamber — the pair of gears, the process connections, the register face as it actually ships — then the displacement string the datasheet already prints. It is not a cinematic keypad inventing litres in 4K, and it is not a Coriolis flowtube with a new caption. Photograph the chamber. Letter the volume. Leave the calibration off the generate.
The oval-gear chamber is the SKU
Positive-displacement OEMs sell a specific geometry: oval gears, a known chamber volume per revolution, a process connection, a register a plant engineer will recognise on a skid. Those live in the photograph. Ask for “an industrial oval-gear meter on a clean skid” and the model will invent a cousin housing: extra flanges, a different register, a rotor that is turbine-shaped. That is a different CV.
Photograph the meter you sell — catalog still or the installed plate on your line. Square to the chamber. Process connections in frame. Register readable only if the glyphs on it are already yours and already true. That still is the print.
Prompt travel only if you later animate the approved plate: a slow orbit that keeps the gears readable, a hold on the housing, no new ports. Do not re-describe “stainless oval-gear PD, 2-inch, 0.1 L/rev.” That paragraph restages the SKU. If the snap is muddy, shoot again. Do not prompt the gears out.
Manufacturers is the plant page — chips, docks, a line you already film. This page is one oval-gear chamber. Do not rewrite the plant tour as a talking proving-stand lecture. Do not invent an opened chamber as a last frame. A generated teardown is a claim.
Displacement volume is a Qwen spec slide
Displacement is a claim. cm³/rev, L/rev, a rated flow at a viscosity — those digits are why a buyer opens the listing. A 0.12 that becomes a 0.10 for six frames is a mis-ship. A register-shaped scribble that does not encode your number is not a calibration.
Qwen Image 3 Text to Image is the stills row when the letters have to read. Catalog facts: Qwen’s third-generation image model, strong prompt adherence, complex text rendering in Chinese and English, intelligent prompt rewriting on by default, 4 credits, 2K max, qualities 1K and 2K. No audio. No duration. Aspects include 1:1, 16:9, 9:16, and 21:9.
Write the exact strings. If a legal or catalog line must stay verbatim, say so in the prompt and inspect the still. Rewriting is a help for scene language, not a licence to paraphrase 0.12 L/rev into “about a tenth.” Set 1K while the words are in draft. Set 2K when the slide is the slide. There is no 4K chip on this row.
A video model is a bad typography engine. It will give you seven frames of almost-volume and a housing legal cannot ship. Do the lock here. Approve the characters. Then, and only then, consider motion or overlay.
Generate a slideshow from a prompt is the named agent job for a planned set: theme, format, slide count, a board per beat. Cost is priced per image, shown before you confirm. Useful for structure — displacement, viscosity, connection, CTA. Dangerous if you let it invent the numbers. Do not brief “typical oval-gear meter.” Write the strings, or generate the lettered Qwen stills and assemble them.
Coriolis already owns mass flow
Coriolis meters overlay mass flow; Veo digits are a fake calibration already spent kg/h and density on the bent-tube still. This listing is not that page rewritten with a different noun. Oval-gear is volumetric: chamber volume, gear pair, a register. Do not overlay kg/h on oval gears because the Coriolis post used that string. Displacement is litres per revolution, a viscosity note if the datasheet has one. Mass flow is the other meter. If the brief says “flowtube” or “kg/h,” you are on the Coriolis page. If it says “oval gear” or “cm³/rev,” you are here.
Veo digits on a PD register are a fake calibration
Do not ask a video model to typeset the register. Video models redraw letterforms every frame. Text you cannot afford to get wrong does not live inside the motion.
Add a text overlay to a video burns one authored line for the whole clip — top, center, or bottom. That is the displacement volume, a CTA, a SKU. It does not transcribe. It does not mint a live register. Overlay after picture lock. Swap 0.12 L/rev for the next SKU without regenerating the gears.
VEO 3.1 is Google’s enhanced Veo row: text-to-video, no still required, native audio, official 4K tier, clips of 4s, 6s, or 8s, 40 credits. It is the cinematic talking and physics row. “Oval-gear register counting litres, engineer nods” on Veo is a performance of calibration. It is not the chamber. It is a number the model improvised, with a soundtrack you did not score, on a faceplate that is not your firmware.
That clip does not become a datasheet because it looks expensive. Official-looking glyphs are not a live zero. Overlay the real string on a locked chamber take. Do not generate the register. If an engineer has a line, that is a different generate, with a real named person, on a different day. Silent chamber. Letter the spec on Qwen. Overlay the digits. Skip the fake calibration.
FAQ
Can I prompt Veo to count litres on the register instead of overlaying displacement?
You can. You should not ship it. Veo 3.1 is 4 / 6 / 8 seconds, 4K, native audio, 40 credits, no still required. It will paint digits, not typeset your datasheet. Letter the volume on Qwen Image 3 at 4 credits, 2K, and overlay the real string on a locked chamber take.
One overlay or a planned slideshow?
One overlay is one string for the whole clip — a volume, a CTA. Displacement, then viscosity, then SKU need either timed overlays or a prompt-planned slideshow with strings you wrote. Neither job transcribes. Neither job belongs in a Veo prompt. The planner must not invent a “typical” L/rev.
Why not reuse the Coriolis mass-flow overlay as displacement?
Because Coriolis already owns kg/h and density on the flowtube still. Oval-gear is volumetric. Overlaying mass flow on a PD chamber is a claim the SKU does not make. Use displacement volume. Keep the pages separate.
Do I always need to animate the oval gears?
No. The spec slide is the listing. Animate an approved chamber still only when a short orbit helps a buyer recognise the housing. Identity of the casting is that job. The math stays on the Qwen board or the overlay.
