SELMA Integrated Tank Level Gauging System relies on modern PLC Platforms and are configured according to ship specific tank gauging specifications and requirements (turn-key solutions).
SELMA Tank Level Gauging System is based on Hydrostatic Level Pressure Transmission technology designed especially for long lasting operation.
SELMA Level Pressure Transmitters are performing tank gauging by hydrostatic pressure that is applied on the transmitter. The direct conversion of the pressure into electrical signal is achieved by a minute deformation of the sensor diaphragm with applied pressure which changes the electrical resistance.
The transmitters are based on rugged and reliable capacitive ceramic sensors qualified for measuring small filling heights with accuracy. Thanks to different housing materials in combination with several mounting types the transmitter covers a lot of applications in shipbuilding.
- Small Thermal Effect
- Excellent Linearity
- Good Long Term Stability
- 0.175% / 0.125% FSO BFSL
- 0.35% / 0.25% FSO IEC60770
(Main Processing Unit) comprising powerful and robust industrial PLC controllers and equipment, is responsible for collecting and processing all the sensor signals and system data through the Remote I/O stations. All the data from the MPU are transferred and communicated to the new Panel PC Workstation for display, control and monitoring purposes, as well as for further post-processing.
The MPU also provides open-standard data outputs for interfacing with the vessel’s Alarm and Monitoring System (AMS) as well as with the Load computer. Furthermore, the MPU has embedded extensive self-diagnostic functions, fully monitoring the health and status of the system and its sensors.
Radar High Frequency microwave pulses are applied and guided along the probe, where the pulses are reflected on the surface and received by the processor module.
SELMA Tank Gauging System display Gross / Net Tank Volume, Sounding, Ullage and Temperature measurements on heavy duty Workstations and Touch Screen monitors.
SELMA experienced engineers undertake retrofit / upgrades design/programming of existing systems where reduced piping requires due that most of the present installation (pipes, flanges etc) remains as fitted.
