Sonda di pressione OTT PLS con cella in ceramica per livello dell'acqua e temperatura

OTT PLS

Resistente cella di pressione in ceramica

La sonda di pressione SDI-12 o 4 ... 20 mA OTT PLS consente di misurare il livello dell'acqua, la soggiacenza o la pressione per mezzo di un controller integrato e di una cella di misurazione della pressione in ceramica.

  • Acqua di superficie Acque sotterranee
  • Cella di pressione ventilata
  • Livello dell'acqua/pressione, temperatura dell'acqua
  • Misurazione continua del livello dell'acqua, da utilizzare con datalogger esterno
  • 0 … 4, 10, 20, 40, and 100 m
  • ± 0,05% FS
  • SDI-12, RS-485 (using SDI-12), or 4 … 20 mA
Radar a impulsi OTT RLS

OTT RLS

Sensore di livello radar senza contatto a basso consumo

OTT RLS è un sensore di livello radar senza contatto con tecnologia radar a impulsi ideale per il monitoraggio in ubicazioni remote o di difficile accesso.

  • Acqua di superficie
  • Livello dell'acqua/soggiacenza
  • Radar a impulsi senza contatto
  • Misura il livello dell'acqua o la soggiacenza da un ponte, molo o braccio di montaggio
  • 0.4 … 35 m
  • 0.8 … 2 m: ± 10 mm; 2 … 30 m: ± 3 mm; 30 … 35 m: ± 10 mm
  • No
  • SDI-12, RS-485 (using SDI-12), or 4 ...20 mA
Codificatore ad albero galleggiante per livello dell'acqua OTT SE200

OTT SE 200

Sensore di livello dell'acqua OTT SE 200 con codificatore ad albero galleggiante

Il sensore di livello dell'acqua OTT SE 200 con codificatore ad albero galleggiante fornisce misurazioni comprovate del livello dell'acqua in monitoraggi continui e non presidiati in applicazioni nell'ambito delle acque di superficie e sotterranee.

  • Acqua di superficie Acque sotterranee
  • Livello dell'acqua
  • Codificatore ad albero galleggiante
  • Misurazione continua del livello dell'acqua, da utilizzare con datalogger esterno
  • ±30 m
  • No
  • SDI-12 or 4 ...20 mA

The Mekong River Commission Secretariat (MRCS) is a Basin Management Organization formed through the Joint-Cooperation by the National Governments of Cambodia, Lao PDR, Thailand and Vietnam. Besides, China and Myanmar are dialogue partners for cooperation with the MRCS.
 
The organization aims at sustainable development on managing water resources, sharing information among the Mekong member countries. In cooperation with the World Meteorological Organization (WMO), MRC established a near-real time Hydro-meteorological network, funded by the French Development Agency AFD.

The MRC hydro-meteorological network is a basin wide hydro-meteorological monitoring system, spatially covering both mainstream and main tributaries of the Mekong River.  The system is integrated into the existing MRCS monitoring system and will also improve the national hydrological networks and river monitoring / forecasting capacities.
The project is managed under the Information and Knowledge Management Programme (IKMP) in the Technical Support Division (TSD) of the MRC Secretariat.
It shall be ensured that all data collected basin wide are made available in a timely manner to the Regional Flood Management and Mitigation Center (RFMMC) in Phnom Penh and other real time users.


The main objective of the MRC Hydro-meteorological network is to establish an efficient, reliable and timely hydro-meteorological data collection and transmission system. The 49 network stations need to provide near-real time water level and rainfall in 15 minutes intervals over the mainstream and main tributaries of the Mekong River.

  • Water level and rainfall measurement stations
  • Remote data transmission via GPRS
  • Installation of the stations at 49 different locations in the different member countries
  • Training of national technical staff
  • 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.
  • Different water level sensor technologies applied, according to individual site conditions:
  • 30 bubble sensors: OTT CBS
  • 9 radar level sensors: OTT RLS
  • 10 shaft encoders: OTT SE200
  • 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

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