Viscometer G19

The G19 is a microprocessor controller for the regulation of the viscosity of water based ink. 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 water 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. Water based ink and varnish.

Console and command screen

HMI 4,3” – 9,7” touchscreen display. All colours displayed on the screen. All viscosities 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 or viscosity over tolerance).

Control G19

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

Viscometer G19-RIV

G19-RIV to install in a danger zone near the ink tank. Water correction through pneumatic valve. Feeding by rotary or alternative pumps. Viscosity accuracy is measured within 1%.


Control pH by G80 probe. Control temperature by G90 heat exchanger. PC 15” touchscreen display. 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.
