Establishment of a Reliable Hydro-meteorological Data Collection & Transmission System

The main objective of the MRC Hydro-meteorological network was to establish an efficient, reliable and timely hydro-meteorological data collection and transmission system.

The 49 network stations needed to provide near real-time water level and rainfall in 15 minute intervals over the mainstream and main tributaries of the Mekong River. 

Background

  • The MRC hydro-meteorological monitoring station spatially covers both mainstream and main tributaries of the Mekong River and is integrated in the existing monitoring system; improving the national hydrological networks and river monitoring and forecasting capabilities

  • The project is managed under the Information and Knowledge Management Program (IKMP) in the Technical Support Division (TSD) of the MRC Secretariat

  • All data collected in the basin will be made available in a timely manner to the Regional Flood Management and Mitigation Center (RFMMC) in Phnom Penh and other real time users

More details:

  • Water level and rainfall measurement stations

  • Remote data transmission via mobile radio communication

  • Installation of the stations at 49 different locations in the different member countries

  • Training of national technical staff

Monitoring Solution

  • Supply of 49 measurement stations with OTT DuoSens Data Logger as turn-key solutions for water level and rainfall measurement, data storage and remote data transmission

  • Installation of the stations in the different member countries by local OTT partner
  • Regional and national training for the operation and maintenance of the stations for the national customer staff

    Different water level sensor technologies applied, according to individual site conditions:

    • 30 bubble level sensors: OTT CBS

    • 9 radar level sensors: OTT RLS

    • 10 shaft encoders: OTT SE200

Advantages:

  • State-of-the-art technology for long-term and sustainable monitoring of hydro-meteorological data

  • Turn-key solution – from sensor & data monitoring to complete installation and set up

  • Best suitable sensor technology for each different type of measurement site

  • Installation: set-up and configuration of stations as well as training for customer handled by a local OTT partner

  • Competent after-sales service provided to the MRC by local partner with support from OTT Hydro service team in Germany
