Viscosity control system for Industrial chemistry

Viscosity control Selevisco 90000: an automatic system specifically engineered for controlling the viscosity of any kind of fluids.

In general, the viscosity characteristics of motor oil and emulsifying oil, ceramic based coatings, textile emulsions and industrial chemical products have to suit different requirements and be controlled constantly throughout all the stages of processing – production, packaging, filling and storage. For engine lubricating oils,whole or emulsifiable, viscosity is a parameter that defines the conditions of use, which can be linked for example to the operating temperature. For ceramic liquids, a programmed viscosity control is essential to maintain a uniform coating thickness and the expected characteristics of the shell. In the textile sector, emulsions have different uses and different desired viscosities that can be controlled by our viscosity control system Selevisco 9000, both during the process of packaging, with monitoring of the in-line viscosity, and during the various stages of production.

SELEVISCO control systems allow the measurement and correction of viscosity of any type of industrial liquid, such as lubricating oils, chemical products for the textile industry, ceramic compounds for coating.

They operate through a patented measuring head placed in line with the flow, a control panel for the display and regulation of the rheologic properties as well as an array of accessories to complete the range of supply.

Thanks to a precise comparative logic the programmed viscosity value is compared to the value detected alarming according to the difference between the values measured by the viscometer and a setpoint. It is also possible to perform only the manual measurement by receiving the detected viscosity value from the system.

Selevisco viscometer can control an ample range of fluids, such as coating of refractory ceramic material (ceramic slurry), lubricating oil for engines or moving mechanical parts, emulsions for the treatment of fabrics and industrial chemical products.
Ensures an elevated measuring accuracy.
Can be personalized and adjusted based on your needs.
Able to read the viscosity value even while the fluids are in motion.
Complete with a temperature control to correct the temperature according to its variation.
Requires minimum maintenance.
Can be integrated in a system for the management of automatic washing cycles.
It is versatile and can be installed in line with the fluid to be measured, or offline, inside tanks or sample containers.

SELEVISCO control systems allow the measurement of the viscosity of fluids through a patented vibrating sensorial system that is submerged in the food fluid to check.
The measuring head is embedded in an extremely resistant capsule, small and with the possibility of being anchored to external supports, thus easily allowing the installation in limited spaces. For food production plants it is possible to use an offline viscosity control system located inside tanks or sampling containers.

Thanks to a precise comparative logic, the system allows the constant maintenance of the correct mixing of different fluids. This type of application can be integrated and customized for various industrial sectors beside food industry.

The SELEVISCO series 9000 has been designed specifically for the control of viscosity, and is also employed in food preparations, emulsions, fluids and liquids.
Our viscometer offers:

Wide range of application: this specific model is designed for viscosity verification within a field of 40 to 500 cps (corresponding approximately to 9 – 120 seconds using a Ford cup size 4) and therefore permits the control of gel, oils, and liquid chemical products.
Extremely high precision: granting an outstanding reading tolerance with the possibility of modulating according to specific needs through personalized modes. The peculiar application allows the control of liquids in flowing conditions, thus permitting its application directly on the supplying pipeline. The system is also equipped with an integrated temperature control for data modulation based on its variation.
Minimum maintenance: the absence of moving elements eliminates the necessity of frequent maintenance. Furthermore, SELEVISCO can be integrated with a system of automatic washing cycles, guaranteeing efficiency and functionality for extremely long periods of time without any special arrangement.
The operating principle of the viscosity system is adaptable to multiple solutions. The main versions provide for the inline installation on the flow meant to be measured, or offline within containers. Both solutions are based on the patented principle of the vibrating reed and guarantee extremely high precision and reliability.

Installation of the
inline vibrating sensor

The measuring head is protected by an extremely resistant capsule of small dimensions, integrating proper anchoring arrangements in limited spaces.

Installation of the
offline vibrating sensor

Based on the vibrating technology, the offline sensor is installed directly into the tank, granting a better ease of use. The offline sensor is easy to clean and resistant to chemical corrosion thanks to its Teflon coating protection.

Operator friendly

The managing software allows data recording on recipes, allowing for setup and operational reputability. The data displaying and the controls are incorporated into the individual synoptics for each measuring unit. Alternatively, the measuring head can be connected to the touch screen operational interface, based on a Windows platform.

Outstanding Precision

Granting an outstanding reading tolerance.
The system integrates a temperature and pH control (option). Minimum maintenance, the absence of moving elements eliminates the necessity of frequent maintenance.

control panels

TECHNICAL INFORMATION

Measuring range: 9…140 second (Ford-4)
Sensitivity: 0,1 sec
Max number of elements: 16 (Version Touch Screen) 1 (Version SV9000)
Alarm signal of viscosity controller: visual, audible and relay output

The SELEVISCO 9000 control panel allows the display of data and command execution.
Each control panel manages a unit of measurement and can be applied within existing frameworks or supplied integrated into custom pulpits.
In manual mode the system displays the viscosity measured by a single sensor and allows the operator to add the solvent to correct the viscosity value.
In automatic mode the system compares the programmed viscosity value and the measured one. Based on the magnitude of this difference new solvent is added to correct the error.

In case of malfunctioning or lack of solvent the system activates the proper visual and audible alarm to alert the operator. The system has been designed to be auto-cleaning. The solvent enters directly in the measuring sensor both during the regulation step and when the cleaning function is activated at the end of the job. Adequate liquids should be used for the washing cycles according to the fluids’ mixture. The supply should be connected directly to an inlet port located on the measuring head. The data displaying and the controls are incorporated into individual synoptics for each measuring unit that can be retrofitted into existing cubicles or integrated on personalized consoles.

Alternatively, the measuring heads can be linked and interfaced to the machineries’ control systems through customized arrangements, or to PC systems with touch screen interface based on Windows operating systems, and complete with a specific software for job statistics.
The measuring heads and the control units are connected by electric wires, thus permitting the installation of these elements even within long distances.
