Viscometer G30

The G30 is a microprocessor controller for the regulation of the viscosity of adhesive, varnish and lacquer. The viscosity measurement is made through a vibration sensor inline with the ink piping without moving parts.
This sensor emits a frequency to the controller that processes the viscosity in seconds (cup ZAHN, FORD etc.) and, then to the solvent valve, which maintains the value according to the reference signal.

The cleaning of the viscometer is made at job end, while washing up.


Rotogravure and Flexographic presses and lamination. Adhesive, cold seal, glow, varnish, lacquer and special inks.

Console and command screen

HMI touchscreen 4,3” – 9,7” display. All colours displayed on the screen. All data are displayed on a graphic bar. Individual cup settings to desired reference. Save up to 50 different jobs. Temperature control function displayed. Error signals (no ink, no water, no liquid or viscosity over tolerance).

Control G30

Rack system cabled by connectors. Installed in a cabinet. Serial communication between HMI and control.

Viscometer G30-RIV

G30-RIV to install in a danger zone near the liquid tank. Solvent correction through pneumatic valve. Feeding by rotary or alternative pumps. Viscosity accuracy is measured within 1%.


Control temperature by G90 heat exchanger. Magnetic filter G70.

Maintenance and cleaning

At the end of the job, the cleaning of sensors is made simultaneously with the press ink cleaning system. No mechanical parts or moving components.
