In 2006 the test rig for water and heat meters, produced in 1995, was converted and renewed in order of the National Weights and Measures Office Sachsen-Anhalt.
The standards, electronic and software were prepared for higher requirements and more flexibly. Also in expectation of the new European Measurement and Instrumentation Directive this reconstruction was necessary.
The flow-standards (MID's), balances, control electronics as well as the computer inclusive software were replaced. The pipe work system, valves and water tanks were maintained and will be used further without substantial changes.
The control is based on special decentralized I/O modules of the company SHF AG, which are connected by an Ethernet network with the computer as process control as well as the balances. For further stages of development it would be possible to use the devices in a Real Time Ethernet network.
The control computer is a usual standard PC. Programming took place with a modern graphic programming surface.
A following development of this test rig for testing heat meters is planned. The control components can be supplemented by further I/O modules. Programming is easily expandable.
An additional extension on the requirements of the new European Measurement and Instrumentation Directive is also possible without problems at short notice.
