Rivertrace Introduces The SMART VISCO Main Engine Sensor


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 monitor incorporates an LCD display that visually indicates all parameters. The viscosity and temperature data can also be easily retrieved using RS485 or a USB stick.

The fuel oil’s viscosity provides a direct indication of its impact on engine performance and efficiency. The availability of this information aid in the prevention of engine damage reduces maintenance costs and helps to minimise greenhouse gas emissions.

Digital service

This SMART VISCO, with its digital capabilities, can be integrated with the RIVERTRACE CONNECTED service to collect and share the data with ship management to monitor and analyse trends in fuel performance at both a vessel and fleet level.

The RIVERTRACE CONNECTED service initiative provides calibration compliance and equipment performance data. It can either be viewed on a cloud platform or shared through an API to the vessel/fleet management systems. The digital service is designed to support customers seeking simplified, continuous monitoring and efficient operations.

Martin Saunders, Managing Director of Rivertrace, says: “Monitoring environmental discharge has been at the core of Rivertrace’s ethos for over three decades. However, in recent years we have also embraced digital transformation and provided solutions to automate and analyse the data by making our services smarter, and by connecting to the marine digital ecosystem. The SMART VISCO probe extends our offering to encompass onboard monitoring and expands our environmental solutions to include minimising greenhouse gas emissions, as well as our oily water pollution prevention system.”

Rivertrace will be showcasing the new efficient SMART VISCO sensor along with demonstrations of the RIVERTRACE CONNECTED service during the SMM exhibition in Hamburg at stand A1.118.
