There are many different viscometer technologies and all have their merits, depending on the application. 

Before you go and talk to any manufacturers, it is important that you know your application specifications and you need to know what to ask so you don’t end up with an expensive paperweight. This guide will help you gather your information upfront so when you do reach out, we can assist you quickly and effectively.

Laboratory viscometers and process viscometers may have some technology and methodology overlap, but the conditions of use are different so we’re going to break this down into two separate groups.

Recently, a few of our team members created a video to help a customer with a minor issue they were having. We thought that if one customer might have the issue, another might, also, so we uploaded the video, How to Remove a Cambridge Viscosity 500 Series Viscometer Piston, in case it could help other customers.

CVI's ViscoPro 2100 helps increase oil recovery by as much as 20%

Jun 23, 2021 11:10:41 AM / by Patrick Riley posted in reservoir fluid, oil reservoir viscosity, viscosity management, in-line viscometers, ViscoPro 2100

In mature, oil-producing reservoirs, conditions like natural fissions in the reservoir rock or resistance from heavier or more viscous oils require enhanced oil recovery (EOR) injection techniques.  Polymer flooding is one EOR technique that is widely used because it can significantly improve oil recovery over conventional flooding. It uses polymer solutions in an aqueous medium to increase oil recovery by reducing the water-to-oil mobility ratio. Managing the viscosity of the EOR polymers at the well head supports efficient oil production, while helping to reduce the amount of EOR polymer needed.

CVI Offers On-Site Service Capabilities

Maintenance is more than fixing problematic equipment. A preventative maintenance program for your lab or process equipment can help you minimize unplanned downtime and maximize efficiency. All instruments operate best when routine maintenance is conducted, and this is true for Cambridge Viscosity viscometers. Even when a CVI viscometer is working perfectly, we recommend a yearly service inspection. To ensure equipment health and optimum performance, CVI viscometers should undergo annual servicing that includes:
  • Annual inspection
  • Cleaning
  • Verification of settings
  • Reviewing historical data and error logs
  • Calibration verification

Oil condition monitoring for lube oil monitoring on screw compressors

Feb 17, 2021 11:55:02 AM / by Patrick Riley posted in viscosity control, viscosity management, compressor viscosity, in-line viscometers, ViscoPro 2100

Managing lubricant viscosity is essential to maintaining the health of a compressor in a process plant, because a single compressor failure can cost $10,000 a day or more in lost revenue. Considering it’s another $10,000 to rebuild a compressor, or more than $100,000 to replace a compressor, maintaining the health and performance of compressors is important.

When your lab measurements are different than the in-line measurements

There is always some level of uncertainty in comparing on-line viscosity measurements with laboratory measurements. When it comes to viscosity analysis, a major reason for that uncertainty – and inconsistent measurements – is because the fluids are, in fact, under different conditions.

Almost two months ago, while those of us in the United States were enjoying our Thanksgiving holiday, our associates in Italy were holding a webinar on viscosity measurement in pressroom converters. This event inspired a series of material discussing the coating application, including last week’s blog highlighting factors that influence viscosity measurement in the pressroom converter application.

Spring and wire products are a substantial market – estimated to reach $468B by the end of 2020. Wire is widely used in manufactured goods, including electronics, automobiles, motors, transformers, and a wide array of other products. The coating on the wire is possibly the single most important variable in wire quality, and viscosity plays an important role in ensuring quality.

In shipping vessels, “bunker” refers to the fuel and lube oils that are stored on the ship and used for machinery operation. When the fuel or oil is intended for transfer to another ship for use in its machinery, the operation to transport the oil is called “bunkering.”

Cambridge Viscosity process viscometers are known for robust operation and reliability in viscosity measurements. Performing scheduled Preventative Maintenance (PM) on your Cambridge Viscosity viscometer is vital to system operation, longevity, and verification.  Cambridge Viscosity recommends performing PM on your viscometer on an annual basis as defined in our Operational Manual.  PM can be performed at more frequent intervals if deemed necessary due to internal QA or other departmental policies.
