Model Selection Viscometers Brookfield | Rongtien Co., LTD
Looking for a lab instrument but not sure which one? Brookfield is ready to help you make the correct choice for your application. Use the model selection guidelines to help you in your decision making process. Still need help? No problem, just call or email us or one of our authorized dealers for an immediate discussion about your requirements.
There may be industry or supplier/vendor specifications that you need to duplicate. Before making a final selection, we suggest that you confer with people in your industry to find out which Brookfield Viscometer they are using so that your data can be correlated.
Brookfield Viscometers/Rheometers are supplied with a standard spindle set constructed of stainless steel (#302), however, other options such as #316 stainless steel, cylindrical, vane or Teflon coated spindles for increased corrosion resistance are also offered. Please call or email for details of when these non standard spindles should be used.
In addition, asking yourself these questions may help determine what – if any – accessories you should be considering.
LAB QUESTIONS
- What is the viscosity range of your material: Low, medium, high?
- What rotational speeds or shear rates are important?
- How much sample is available for testing?
- Is temperature measurement/control necessary?
- How will you record the viscosity data?
Interested in an inline instrument but are unsure of what you need? You should contact us by email or phone. A trained sales engineer will probably start off by asking the following questions:
PROCESS QUESTIONS
- What is the viscosity range of your material?
- Is your material Newtonian, Dilatant, Non-Newtonian, Thixotropic or Plastic?
- What is the minimum, maximum and average pressure requirement of your application?
- What is the minimum, maximum and average temperature of your application?
- What is the minimum, maximum and average flow rate of your application?
- Where in production would you like the viscometer: in-line, on the top of the tank or on the side of the tank?
- What electrical code requirements do you have:
- NEMA 1 (general purpose-indoor)
- NEMA 4 (watertight/dust tight for indoor/outdoor use)
- NEMA 7 (explosion proof-Class 1, Div. 1&2, Group D)
- ATEX (explosion proof-Code: EE x d 11B T6)
The above parameters may eliminate some of the instrument models because, for example, the viscosity is higher than the range of the instrument or outside of the pressure rating of the instrument. In many cases, more than one instrument may be applicable.
Please allow us to assist you in choosing the best viscosity control system for your application.
