(((•))) Kockum Sonics Electro pneumatic level and draught gauging General Information The new generation of Levelmaster is named H8 and is the successor of the well-known CALM system. Level gauging using the electro-pneumatic principle, so called 'bubble measuring', has always been known as a very robust and reliable method. Kockum Sonics now release its fourth generation of the electro-pneumatic system concept. We have combined the latest and best sensors and microprocessors in order to produce an electro- pneumatic system that combines low cost and very high performance. The heart of the system is the integrated sensor and control unit (SCU). It takes care of all data acquisition, calibration, control and transmission. The SCU is developed by Kockum Sonics and tailor made to suit electro-pneumatic tank and draught gauging. Each pressure sensor has been calibrated for non-linearity and temperature shift in order to provide optimal performance. While in operation the system auto calibrates at pre set intervals, which maintains the system accuracy. The SCU is adaptive and precisely adjusts the needed air output for each tank. Simplify operation Increase accuracy Reduce investment costs Reduce maintenance costs The new Levelmaster H8 is packed with new and improved technology. First of all the system is fully modularised making for very easy service. Secondly the new Levelmaster H8 software driver makes integration with other systems easy and straightforward. All collected data can be made available overa standardTCP/IP network.The software driver is also used to monitor the status of the system. Diagnostics can be run from any connected computer with the driver installed. High accuracy with automatic system calibration Adaptive level sensing Automatic purge High update speed No electrical parts in EX zone Small dimensions Easy installation Maintenance free The Levelmaster H8 system will be delivered with all components mounted in a powder coated steel cabinet.

Adaptive Level Sensing Levelmaster H8 is an intelligent system. It automatically senses and compares measured levels making the system adaptive. When the level in the tank increases, more air is given in order to ensure that the tank filling speed does not have an effect on the measurement. Automatic Leakage Detection If the ship pipes to the tanks are not completely air tight, the Levelmaster H8 system will detect the leaks. At small leaks the system reacts by purging the tank with longer intervals in order to minimise the effect on the measurement. The error will be negligible. In...
