Dam Level Measurement – Overview This system is used for high precision level measurement, volume calculation, and hydrostatic or pneumatic pressure measurement. This can be installed pneumatically or hydrostatically. Pneumatically, the sensors measure the counter-pressure produced by an air compressor, thus having no direct contact with the water. Hydrostatically the sensor comes into direct contact with the water. This cost-saving system optimises the water balance measurement. It does multi-point measurements with one controller. It is also highly durable and maintenance-free (no recalibration required). A normal web browser is used to connect to the instrument. Thermal compensation with a quartz crystal temperature signal is used to counteract sensor performance when the sensor efficiency is affected by temperature fluctuations. Dam Level Measurement – Features Up to four measurement sections per Controller Transmitters for hydrostatic or pneumatic pressure measurement 100% thermal compensation with quartz crystal Temperature signal Very accurate calculation of storage water volume: resolution < 1 mm H2O Excellent accuracy of typical < 0.01% FS (quartz crystal sensing element) Superior stability – near-zero drift of sensing technology IEC 60870-5-104 and Modbus communication Fits to all standard PLCs Controller with built-in web server for easy configuration
