Rheonics SensorView connects to inline viscometer SRV and inline density meters SRD, DVP, DVM wirelessly using Bluetooth LE built into the display module of the SME-TRD electronics. SensorView shows all the measurements from the sensor * viscosity * density * kinematic viscosity * temperature Real-time graph shows the updated measurements from the instruments. Users can select the parameters to show on the chart by clicking the measurement display buttons. Future versions will also add the ability to show estimated parameters like * concentration * API density * temperature compensated viscosity * temperature compensated density SensorView is consistently updated with new features. We love hearing from you how you use the app and what new features you would like us to add.

BYK Viscosity Calculator

Features
Read full description

Simply input either a drain time or viscosity into one of the given input fields and then select the type of viscosity cup you are working with to calculate the viscosity or drain time of your sample. If the selected cup is highlighted in green that means you are within the cups viscosity range and the number is valid. If you are outside of the cups range an error message will appear, meaning you are outside the tolerance range of that given cup. If this appears please use a different cup that would be in range for what you would like to test. You can see what cups are in range for your desired value by inputting the value you want to test and scrolling through the list, any cup in green will be able to provide a valid measurement for the desired input.
