Flow Cups

Flow Cups

The various viscosity cups comply with the relevant standards and are delivered with a certificate.

Ford Flow Cups

BYK-Gardner Ford Viscosity Cups are guaranteed to be within 3% (drain time of calibration oil) throughout the recommended use range.

  • For low viscosity liquids
  • Body made of solid bar aluminum
  • Stainless steel orifice
  • Calibrated against standard oils referenced to certified NIST oils (National Institute of Standards and Technology of United States)
  • Certified cups available on request

 

Standards:

ASTM D333 D365 D1200

The following Ford cups are available:

  • Ford Cup No. 2     (25-120 cSt.)
  • Ford Cup No. 3     (45-220 cSt.)
  • Ford Cup No. 4     (70-370 cSt.)

 

DIN Flow Cups

This cup holds 100 ml ± 1 ml, and has an integrated orifice with a diameter of 4 mm ± 0.02 mm.

  • For low viscosity liquids
  • Body made of anodized aluminum
  • Stainless steel orifice, interior polished
  • Calibrated against standard oils referenced to certified PTB oils (Federal Institute of Physics and Metrology of Germany) to be within 3% (drain time of calibration oil)

 

DIN Auslaufbecher

Standards:

DIN 53 211*

*Note: DIN 53211 was withdraw in October 1996

The following DIN cups are available:

  • DIN Flow Cup 4mm    (100-500 cSt.)
  • DIN Flow Cup with interchangeable orifices (2, 3, 4, 6, or 8mm)
    (not certifiable)

ISO FLow Cups

This cup has a longer orifice, less tapered body and slightly different inner dimensions than the DIN 53211* flow cup and thus provides different efflux times. The extended measurement range makes the ISO cup a useful supplement of the DIN cup.

  • Recommended for international use
  • Body made of anodized aluminum
  • Stainless steel orifice, interior polished
  • Calibrated against standard oils referenced to certified PTB oils to be within 3% (drain time of calibration oil)

 

ISO Auslaufbecher

Standards:

ASTM D5125
ISO 2431

The following ISO cups are available:

ISO 3 mm      (10 - 40 cSt.)
ISO 4 mm      (25 - 130 cSt.)
ISO 5 mm      (70 - 370 cSt.)
ISO 6 mm      (130 - 700 cSt.)
