Ⅰ. General Description:
T-4 Flow Cup:
It is applicable to the determination of viscosity of a certain coating materials of which the flow time determined by it is under 150s.
ISO Flow Cup:
It is applicable to determine the flow time of Newtonian and near Newtonian model fluids. It is suitable for testing kinematics viscosity range of sample within 7-685mm2/s.
Ford Cups:
Ford Cups is an instrument to determine the viscosity of Newtonian or near- Newtonian paints, varnishes, and related liquid materials. The Ford Cups is filled level full with the liquid under test, and the time for the material to flow through one of the standard orifices is measured. This test method is useful for the determination of package and application viscosities of a number of paints and other coatings and in the thinning of these materials, but is limited the Newtonian or near- Newtonian liquids. A cup can produce satisfying and reproducible results when used within its defined viscosity range. Ford Cups is not suitable for measuring high viscosity liquids, pastes, etc.
The machine is used for chemical material process, safety and health protective step must be set up in accordance with all local codes and ordinances. Before using this machine, safety problem associated with chemical material must be established by user, not belonging to explanation of this Instruction Manual.
DIN Cup:
DIN cup is designed for quick, approximate determination of efflux times for paints, and similar liquids in workshops. In accordance with Deutsche Normen DIN 53211.

Ford Cups:Where: ν— kinematics viscosity mm2/s
t — flow times (measuring value should be within 30-100s)
Ford Cups produced by our company is in accordance with specification of ASTM D1200. Ford Cups is made of corrosion-and solvent-resistant material, material of Ford Cup Body is aluminium alloy, material of Ford Cup Orifice is brass, which is subject to wear with use and cleaning. We adopts similar ISO Flow Cup model, different from ASTM D1200 recommended model, it is easily cleaned & more firmly placed. Each single cup is calibrated against standard oil in a factory. If orifice is loosened or taken out from a cup, the cup should be recalibrated.
| Cup No. | Range in centistokes | Efflux Time(seconds) |
| Ford Cup 2 | 20-120 | 40-100 |
| Ford Cup 3 | 49-220 | 20-100 |
| Ford Cup 4 | 70-370 | 20-100 |
| Ford Cup 5 | 200-1200 | 20-100 |
Remarks：Packing size：205×125×306，Gross weight：1.95kg
The following formulas are used to convert the time of flow in seconds, t, to kinematic viscosity V:
Ford Cup No.2 V=1.44(t-18)
Ford Cup No.3 V=2.31(t-6.58)
Ford Cup No.4 V=3.85(t-4.49)
Ford Cup No.5 V=12.1(t-2)
Centistokes×Specific Gravity=Centipoise
