Bangkok Municipality Trusts in Measurement Equipment

Sommer (Austria) provides Bangkok with the radar discharge sensor RQ-30 to monitor the discharge and water level of main rivers and canals flowing into the city.

Sommer is a family owned company with long experience in developing and producing high quality sensors for meteorological and hydrological application. Besides snow monitoring sensors and automatic weather stations, Sommer’s core competence is discharge measurement of rivers, canals or streams.

Due to the geographical location and the monsoon season beginning end of July, Bangkok is threatened by floodings every year. Besides the Chao Phraya river a complex system of canals crosses through Bangkok. Exact information about the water level and the discharge of these rivers and canals is essential for an optimised water control.

The Sommer RQ-30 is a unique radar sensor which measures contact free the water level and the velocity of the river in real time. The sensor automatically calculates the discharge based on a complex hydraulic model. The main advantage of the sensor is that it is installed outside the water. Therefore, it is maintenance free and gives reliable results especially during high flow condition.

With AMR Asia Sommer had an excellent local partner, who implemented the sensors into the municipal SCADA system.
