The SMART VISCO is a Fuel Condition Monitor


Related Product Information

The SMART VISCO monitor is designed to measure the viscosity and temperature of fuel oil on board large ships prior to entering the main engines. The monitor will be installed in the fuel line prior to injection and will report temperature and viscosity data over analogue/digital outputs and volt free relay contacts.

The SMART VISCO  monitor can measure all HFO types online using ultrasonic guided wave technology. Due to the high frequency and speed of ultrasound, ambient vibration and flow speed have no impact on the measurements. The monitor has an LCD display that shows all parameters. The viscosity and temperature data can also be easily retrieved via RS485 or a USB stick.
