ATM.ECO/N - Analog Level Transmitter
Fully submersible pressure transmitters designed for the long term monitoring of depth and level measurements.
• Excellent long term stability allow accurate measurements over a long period
• High measurement accuracy is ensured by sophisticated digital temperature compensation algorithms
• Fast customisation thanks to configurable product design
• Available with over-voltage protection
The ATM.ECO/N is part of a comprehensive range of pressure transmitters specifically designed for the long term monitoring of ground water and wastewater. Features such as Kevlar strengthened cable, titanium, ballast weights, data loggers, etc. broaden the installation opportunities. The modular construction provides manufacturing flexibility and offers fast delivery for all pressure ranges and standard options.
Examples of applications include:
– Wells, lakes and reservoirs
– Bore holes
– Surface water, irrigation canals and rivers
– Wastewater and sewage treatment plants
– Tank level measurement
