The ATM.ST/N/T series is part of a comprehensive range of transmitters specifically designed for the long term monitoring of ground water, wastewater and tank level measurement. It provides a dual 4-20mA, 3 or 4 wire configuration for both level and temperature. Features such as Kevlar strengthened cable, titanium, ballast weights, dataloggers, etc. broaden the installation opportunities.
Examples of applications include:
• Deep wells, lakes, dams and reservoirs
• Bore holes
• Surface water, irrigation canals and rivers
• Wastewater and sewage treatment plants
• Tank level measurement
