Optiflex 1300C guided wave radar tide gauge
The Krohne Optiflex 1300C radar is a contact type measurement sensor (the water interface measured is in contact with the instrument). These are guided wave radars using TDR (Time Domain Reflectometry) measurement technology. The instrument transmits short electromagnetic pulses along a conducting cable. The pulses are then reflected by the surface of the water and received by the apparatus, which measures the time between the transmission and reception of each pulse. Half of this time is equivalent to the distance between the sensor's reference point and the surface of the water. Optiflex 1300C sensors are now replacing the older generation BM100A radar tide gauges. They offer higher measurement quality (improvement of radar signal characteristics) as well as lower power consumption.
Tide gauge deployment
These sensors are installed in stilling wells with a diameter of at least 300 mm and whose characteristics range from old stone stilling wells (Brest, Socoa etc.) to polyethylene tubes (Saint Nazaire, Port-Bloc etc.).
