Hi, I am looking to build a prototype that will be able to measure viscosity using a stirring device. A general idea to this process is that the liquid will first be cooled to approximately 30 degrees celcius and then using a stirring device, the viscosity of the liquid will then be calibrated. I wo…

As a zero-order guess: Viscosity will correlate to torque and torque will correlate to current into the motor. If you have speed control (feedback using an encoder, for example), you can probably deduce viscosity from the current measurement. You'll need to calibrate the system with liquids of kno…

will it be more accurate than using a flow rate sensor that calculates the viscosity using the time of flow? given the liquid that is used is quite viscous Blackfin: As a zero-order guess: Viscosity will correlate to torque and torque will correlate to current into the motor. If you have speed c…

I am not expert to built the system but I used both type of system which measure the viscosity with rotation (metal ball rotating inside liquid with magnetic field) and flow based viscos meter (flow passed through narrow plates and two sensor which detect the liquid and calculate the viscosity based…

I did a photo shoot for an oil analysis manufacturer a few years ago. One of the measurements, of course, was viscosity. The instrument used a constructed tube and measured the pressure before and after the constriction.

I am actually considering using the flow rate sensor to calculate the viscosity. My question is will it be accurate relative to the viscometers that are out in the market right now? If not, how far off is the flow rate sensor?

If you are building something designed to compete with existing products then I don't think that using an Arduino is going to magically make it cheaper to build. The main cost is in the sensors, motors, power supply, mechanical construction, certification etc. However, it wouldn't surprise me if th…

jeremychan98: I see. In terms of building it, which one is more complicated and requires a higher skillset? It may help you : MiniVisc 3000 See that video after 03:00 min

Hi, Is there any ultrasonic or laser viscometer in the market or someone made or tried? Is there any possibility to measure the viscosity without touching the liquid? Any idea?

Hi jeremychan98,

I am planning to make viscometer via DIY. Based on Torque and current. Can anyone guide me on this topic?
