Installation & Instruction Manual
The Model 970-C Sugar Consistency Monitor reliably measures massecuite consistency in sugar vacuum pans, providing a continuous indication of this important variable in pan operation over all ranges encountered in high- or low-grade sugar boiling.
The 970-C Consistency Monitor is a convenient guide for experienced operators and an invaluable tool for training new sugar boilers. Since optimal consistency varies by pan, operators can experiment to find the ideal level for a particular pan. Using the 970-C monitor to maintain this level, boilers can avoid excessively "tight" massecuites and therefore avoid poor pan circulation. Likewise, operators can pinpoint an optimum dropping consistency that produces high crystal yield without unduly long discharging time. The zero and span adjustments expand readability in critical viscosity or consistency ranges.
The narrow viscosity range is useful in measuring concentration in sugar melters, evaporator syrups and molasses dilution tanks, and even slurries such as milk of lime where density is a troublesome measurement and can introduce serious time lags into control loops. It can also measure the concentration of evaporated whey, distillery slops, fruit and vegetables or tomato products.

Typical Sensor Mounting
Normal probe location is in the side of a vacuum pan so the rotor is about midway between the lower tube sheet of the calandria and the pan bottom. Preferred mounting is shown in position A with a slight downward angle so that the rotor will be in an area of good massecuite circulation, although horizontal mounting as shown in position B is satisfactory. On some pans, it may be necessary to install through the pan bottom to get the rotor in a good free area as shown in position C. However, the mounting angle should not be over 75 degrees from horizontal as there is danger of purge water leaking into the motor bearings. The rotor should be located between syrup feed inlets and away from any obstruction, so that it will measure a freely moving sample of average massecuite.
