Before fuel oil is injected into the primary engines of big ships, the SMART VISCO sensor is intended to measure the temperature and viscosity of the fuel oil. The monitor then transmits this data via volt-free relay contacts on both analogue and digital outputs.
Direct indication
The SMART VISCO sensor measures all grades of HFO 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...
