Bamo Air bubbling level transmitter BAMOBUL

BAMOBUL is designed for Venturi channel or Weir plates (documentation 755-01) water level measurements up to 500 mm.
This application requires a highly accurate level measurement as between water height and level the relation is exponential.
The instrument is associating an air generator to a 4-20 mA pressure transmitter extremely accurate. The sensor permanently measures the necessary pressure to create bubbling against the water column.
This pressure difference is directly proportional to the water height (the pressure is equal to hydrostatic pressure of water column).
To limit errors due to the airflow fluctuation, adjustment are easy with integrated valves. Access to the “0 flow rate” calibration and the full measurement scale are permitted to the end-user.
This instrument is well known for its reliability and the accuracy of signal output even whit particles in the fluid or foam over the surface.
