Visc-Easy ®
Innovative Technology For You
Patented Technology
Sofmares uses an unique patented technology for the sensor which has already been proven for more than 30 years for the measurement of viscosity in various industries, fluids and viscosities. In
this way, Sofmares can ensure that every Visc-Easy ® we sell is the most accurate and reliable in the world. The design is made by the best developers and designers in the world, who earned their credits with several international design awards and patents.
Reliability & Accuracy
The Visc-Easy ® of Sofmares can measure the actual dynamic and kinematic viscosity in the range of 0-25 or 0-50 cSt or any other range on request. The Visc-Easy ® of Sofmares has been designed to deliver maximal precision. Because the rod displacement is high and fully digitally controlled, vibrations have no effect whatsoever. The Visc-Easy ® has the highest absolute maximum ratings in its field.
Installation and Operation
The Visc-Easy ® is especially designed to make operation and installation very Easy. The system has no moving parts or sensitive piezo's. The sensor is calibrated off-factory and never needs to be re-calibrated.
Sensor Housing Material
:Cast Iron or SS316L Flange
Connections :DN40, 50, DIN, JIS Orientation
:Angled or straight line Pressure
Rating :PN40 Weight
:8-9 kg Flow Rate :enough
Working Principle
The measuring principle of the Visc-Easy ® is based on an oscillating rod inside the flow of the fluid. The shear tension of the fluid will damp the amplitude of the rod. The magnitude of the damping is a direct function to viscosity. The rod is fully controlled by a 100Mhz DSP that results in 300 viscosity, density and temperature measurements per second.
Standard Design
The Digital Viscosity System is designed for full flow, in-line installation in heavy fuel oil applications. The electronics is placed in an ultra robust die-cast enclosure, withstanding the harshest environ-ments in marine applications. The sensor comprises an oscillating rod, connected to the electronic enclosure by a 5m cable. The housing has standard flanges for installation.
