AI Technical Summary
Conventional viscosity measurement devices lack reproducibility in start and stop times due to manual operation, leading to inconsistencies in viscosity determination.
A mechanical lever control mechanism with a precisely guided valve at the bottom of the cup, integrated with an electronic time recording system, ensures precise and automatic start and stop times, allowing for electronic evaluation and temperature compensation.
Enables one-handed, reproducible viscosity measurements across a wide range of viscosities, with no liquid loss or dripping, and provides immediate electronic results.

Abstract
Description
1. Technical field and background
[0001] The invention relates to devices for determining the viscosity of liquids by measuring the dispensing time. Conventional ISO or Ford cups have an open outlet, the opening of which is released by lifting or pulling off the cup. The start time is therefore manual and less reproducible. The Unipup V1 improves this process through a mechanical lever control and optional electronic time recording. 2. Structure and features 3. Operating principle
[0002] By pressing the lever, a precisely guided valve at the bottom of the cup opens, releasing the dispensing liquid. A return spring closes the valve when the lever is released. The measurement time can be recorded manually or automatically by the processor module integrated into the handle. The system calculates the viscosity using a stored calibration formula and displays the value directly on the screen. 4. Advantages over the state of the art
[0003] One-handed operation with reproducible start and stop times. Large measuring range from water to highly viscous oils. Electronic evaluation and temperature compensation. Compact design, portable and suitable for field use. No liquid loss or dripping during start-up. Reference symbol list 1 mounting base for electronic module 2 Seat for the measuring cup 3 spouts 4.
