Ariston Norway - Level-Gauging Tank-Monitoring Systems

Ariston Norway was established in 1996 as a recognised manufacturer of high-quality, reliable, automatic systems for level gauging, monitoring and control of levels, temperatures and pressures for the marine industry.

Ariston Norway specialises in the development and manufacturing of technologically advanced automatic level-gauging multipurpose tank-monitoring systems by supplying the marine industry with the Surveyor™ product.

Multipurpose tank monitoring and control system

The Surveyor system is one of the most comprehensive and accurate in the market, utilising tailor-made, high-quality radar and pressure sensors with integrated temperature measurement.

Surveyor systems are advanced, highly technological and user-friendly, and easily integrate into other parties' automation systems. Display of information and the elegant user interface make Surveyor systems easy and simple to use.

Surveyor offers a universal and flexible solution for monitoring of tank levels (cargo, ballast and service), tank and manifold pressures, temperatures, draft, etc., and delivers the information to ships' automation systems.

Tank monitoring and control system features

Features of the Surveyor multipurpose tank-monitoring system include:

• Automated cargo level monitoring
• Independent high level and overfill alarm
• Pressure monitoring
• Ballast level
• Tank temperature monitoring
• Integrated valve and pump control
• Water ingress detection and dewatering system
• Service tank level
• Loading calculator
• Oil-water interface detection

TDU control unit and configurable software

The system features a TDU display unit with colour touch-screen and configurable software via a Windows®-based configuration program. Local set-up of display functions and measurement units makes the interface user friendly and easy to operate.

The unit's sleek design, size and easy installation contribute to creating more human friendly and ergonomic environment solutions. Through virtually unlimited expansion possibilities the system can handle a virtually unlimited number of channels, adding or removing monitoring points howsoever a need arises. Configuration of a new monitoring point or update of the configuration can be done on-site by connecting the control unit TCU to a PC via a serial line.

The TCU control unit performs all the processing of the signals from the I/O cards and supplies power to the I/O cards and the display unit. The control unit supports communication protocols to the majority of makers' automation systems – for example digital I/O and thermocouples.

Customised software, friendly interface and expandability possibilities make the Ariston multipurpose monitoring and control system a cost-effective and efficient solution.

Pressure-sensor technology

Surveyor systems are based on proven pressure-sensor technology, giving accurate information through direct measuring of cargo level, temperature, vapour pressure and cargo density. The pressure sensors have a track record of long-time stability and accuracy.

Customised pressure sensors

The tailor-made high-quality pressure sensors measure absolute pressure. Sensors are hermetically sealed without any ventilation to the atmosphere. Reference is made through an additional sensor, which reads the atmospheric pressure on a continuous basis. Temperature measurement is integrated in the sensors for correction of the pressure-reading accuracy, as well as a separate temperature-monitoring feature.

Hull stress and stability calculator

The system is recommended for installation in cargo tanks, ballast tanks, fuel-oil tanks and for draft measurement. The sophisticated and user friendly on-line / off-line loading calculator is capable of presenting hull stress and stability calculations – allowing printouts of cargo transfer reports – making it an integral part of the system.

Automatic oil-water interface detection system

The Surveyor automatic digital microwave oil-water interface detection system with tank level and temperature monitoring is designed to detect oil-water interface in oil and product tanks – both on vessels (COT, FSO, FPSO) or in land-based tanks (tank farms). Water-oil interface is detected by the dielectric properties of the water.

This oil-water interface detection system uses submersible microwave radars, IP68, EEx and a 2in diameter probe. It is approved by all major classification societies.

There are two ways to detect the oil-water interface: dynamic and static. The dynamic method is based on moving the sensor to enable it find the interface. The static method is based on fixing sensors at a predefined height, waiting for the interface to reach the sensor.

This system can be used as a stand-alone solution or as a part of a complete tank gauging system: level, temperature, pressure, weight, oil-water interface detection, with alarms.

Long-term after-sales support

The focus in Ariston Norway is on quality and performance – from devising tailor-made system solutions to long-term warranty periods and excellent after-sales support worldwide.
