An automatic on-line viscometer for the measurement of non-Newtonian viscosity for process control applications
Summary A coaxial cylinder viscometer, which is available commercially, has been converted into an automatic instrument by replacing the manually-operated speed-selection switch with a cam timer and solenoid-operated switch. This enables the viscometer to operate using a pre-selected sequence of rot...

| 520 | |a Summary A coaxial cylinder viscometer, which is available commercially, has been converted into an automatic instrument by replacing the manually-operated speed-selection switch with a cam timer and solenoid-operated switch. This enables the viscometer to operate using a pre-selected sequence of rotational speeds. The torque due to the fluid at each speed is measured by a built-in potentiometer and the electrical signal from this is recorded on punched tape using a data-logger. The conversion of the torque-speed data into shear stress/shear rate relations is carried out with the aid of a digital computer using the explicit formulae that exist in the literature. The computer programme incorporates routines for data smoothing and curve fitting, in which the latter allows for the differentiation of the torque-speed data demanded by the use of the explicit formulae. Although this instrument may be used as a laboratory viscometer to facilitate viscosity determination, it has been developed primarily as an on-line viscometer and will be used for gathering information on the non-Newtonian properties of a process fluid in order to determine how these are affected by different material variables. This appears to be the necessary first step in developing control instrumentation for processes in which the flow properties of the fluid are important. | ||

The torque due to the fluid at each speed is measured by a built-in potentiometer and the electrical signal from this is recorded on punched tape using a data-logger. The conversion of the torque-speed data into shear stress/shear rate relations is carried out with the aid of a digital computer using the explicit formulae that exist in the literature. The computer programme incorporates routines for data smoothing and curve fitting, in which the latter allows for the differentiation of the torque-speed data demanded by the use of the explicit formulae. Although this instrument may be used as a laboratory viscometer to facilitate viscosity determination, it has been developed primarily as an on-line viscometer and will be used for gathering information on the non-Newtonian properties of a process fluid in order to determine how these are affected by different material variables. This appears to be the necessary first step in developing control instrumentation for processes in which the flow properties of the fluid are important.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Torque</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Explicit Formula</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Coaxial Cylinder</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Process Fluid</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Automatic Instrument</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Davis, J.

An automatic on-line viscometer for the measurement of non-Newtonian viscosity for process control applications |
| abstract |
Summary A coaxial cylinder viscometer, which is available commercially, has been converted into an automatic instrument by replacing the manually-operated speed-selection switch with a cam timer and solenoid-operated switch. This enables the viscometer to operate using a pre-selected sequence of rotational speeds. The torque due to the fluid at each speed is measured by a built-in potentiometer and the electrical signal from this is recorded on punched tape using a data-logger. The conversion of the torque-speed data into shear stress/shear rate relations is carried out with the aid of a digital computer using the explicit formulae that exist in the literature. The computer programme incorporates routines for data smoothing and curve fitting, in which the latter allows for the differentiation of the torque-speed data demanded by the use of the explicit formulae. Although this instrument may be used as a laboratory viscometer to facilitate viscosity determination, it has been developed primarily as an on-line viscometer and will be used for gathering information on the non-Newtonian properties of a process fluid in order to determine how these are affected by different material variables. This appears to be the necessary first step in developing control instrumentation for processes in which the flow properties of the fluid are important. © Dr. Dietrich Steinkopff Verlag 1969 |
