The model 1077 small
bore viscometer is completely automatic process steam analsyer for measuring
viscosity in absolute units. When used with a density measurement, correlation
with ASTM D445 can be achieved.
The Model 1077 Hallikaninen analyser is
suitable for use with newtonian samples which are not sensitive to shear

The Model 421
analyser measures differential pressure across a capillary through which a
fluid is passed. The differential pressure is proportional to the absolute
viscosity of the fluid as described by the hagan-poiseuille equation
A
precision pump meters the flow sample. To ensure that the sample metered by the
pump is at approximately the same temperature as the sample entering the
capillary, two heat exchanges are fitted, one either side of the metering pump.
Input pressure is set so that the metering pump suction pressure is always
positive.
The sample flows at a constant rate through the capillary
across which a differential pressure transmitter is connected. |

The transmitter is
isolated form the sample by diaphragm seals to prevent obstruction of the
impulse lines. The output of this transmitter is the directly proportional to
the absolute viscosity of the sample.
The critical components are
maintained at a fixed temperature by immersion in an oil , the temperature, of
which , is controlled by a precision, temperature controller, heater and when
necessary, water cooling. The temperature is monitored by the relevant ASTM
(IP)_thermometer. |
