  • Automatic data transmission and error messages/remote maintenance via GPRS
Capacity Utilisation Measurement and Ex-proof Data Transmission via GPRS
Installation principle
Capacity Utilisation Measurement and Ex-proof Data Transmission via GPRS


  • The portable flow measurement system PCM Pro with an Ex-proof GPRS data logger Type NivuLog Ex have been used.
  • The built-in pressure measurement cell of the flow velocity sensor allows to detect the channel overflow.
  • Using an additional air-ultrasonic sensor (LUS) ensures reliable measuring of even lowest discharge during the night.
  • Highly efficient data compression as well as the particular transmission behaviour guarantee reliable data transmission despite mas­sive channel walls and metal manhole covers.
  • The NIVUS "Device to Web" data portal allows direct access to the measurement system as well as to the connected sensors.
