Water level measurement

OTT ecoLog 1000 is a compact all-in-one system for measuring water level, temperature, and conductivity (optional). It guarantees real-time, reliable measurement data transmitted online via the GSM network. The device is operated via a smartphone or computer using the built-in Bluetooth (BLE) module. Basic maintenance tasks, such as battery or desiccant replacement, require no tools and can be performed on-site. The device is compatible with Windows, iOS, and Android operating systems. Thanks to its new hardware platform, remote data transmission and parameter adjustments are possible, minimizing the need for service visits.

ADVANTAGES

• Integrated 4G/2G or IoT LTE-M cellular modem
• Wireless local communication via Bluetooth Low Energy (BLE)
• Local communication through the app (Android, iOS, Mac, and Windows 10 devices)
• Remote service access via GSM network, station management through Hydras 3 net system
• Robust construction – hydrostatic sensor with a ceramic membrane, probe made of 904L steel
• Intelligent energy management
• Measurement cable can be shortened on-site
• Alarm statuses sent directly from the device to individual recipients via SMS
• Installation inside a protective pipe: all components are installed in a hidden and inaccessible location, reducing the risk of vandalism
• Battery life: up to 10 years, batteries can be replaced on-site without additional tools

APPLICATIONS

• Surface and groundwater monitoring
• Short- and long-term measurements
• Remote access to measurement data
• Remote locations without infrastructure
• Collecting precise real-time water level data
• Monitoring water level changes, drought events, climate change, water resources, and usage

Used by:

• National and local monitoring networks
• Water resource managers, scientists, engineers
• Universities and research institutes
• Consulting and advisory companies

OTT PLS measures water level, depth, or pressure using a hydrostatic sensor with a ceramic membrane integrated with an advanced signal converter. Design features such as multiple communication outputs (SDI-12 or 4…20 mA), stainless steel housing, and a tensile-resistant cable make this sensor an ideal tool for water level monitoring in various applications.

ADVANTAGES

• The ceramic measurement cell stands out for its high mechanical resistance and top-level accuracy. Unlike typical metal membranes, it is not prone to deformation after prolonged use, ensuring measurement stability.
• Durable design: the ceramic cell is highly resistant to overload (withstands pressure five times greater than the nominal measurement range). The device housing is made of high-quality corrosion-resistant stainless steel. The probe is well-suited even for installation in seawater.
• Built-in microprocessor: compensates for the temperature effect on measurements and adjusts for gravity and water density variations.
• Atmospheric pressure compensation through a capillary tube connected to the sensor eliminates its influence on the level measurement.
• The highly durable cable is equipped with a Kevlar core to stabilize length.
• Simple configuration and connection to an external data logger with SDI-12 or 4–20 mA input interface.
• Optimal measurement resolution — the ability to assign the 4–20 mA output signal to the portion of the measurement range needed for the installation.
• The probe can also output water temperature (only with SDI-12 interface).

APPLICATIONS

Surface and groundwater level measurement in various conditions, including:

• Areas with steep banks, such as flood levees
• Pipes and piezometers with a small diameter (from 1 inch)
• Hydrotechnical structures, weirs, and irrigation systems
• Water channels that periodically freeze
• Seawater and inland waters
• Water channels that periodically dry out (e.g., retention reservoirs)

OTT CBS is a pneumatic sensor for surface water level, known for its compact design, measurement accuracy, and very low energy consumption. OTT CBS meets USGS (United States Geological Survey) requirements for measurement accuracy and long-term stability. The sensor has both SDI-12 digital output and 4-20 mA current output.

ADVANTAGES

• High measurement accuracy — meets USGS (United States Geological Survey) requirements for water level measurement accuracy and long-term stability
• Comprehensive solution in a single device — combining the OTT CBS sensor with the EPS-50 bubbler head eliminates wave interference, ensuring clean measurement data
• Maintenance-free — does not require desiccant replacement, pneumatic component maintenance, or lubrication
• Easy configuration and setup — configuration via micro-switches, connection to existing measurement installations using a 3/8” or 4 mm outer diameter capillary (no mounting adapters required)
• Compact — small, efficient micro-pump motor provides sufficient performance for bubbler method measurement
• Low energy consumption — intelligent measurement procedure; the sensor compares the previous measurement result with the current pressure value to adjust the air pumping time (small level changes are measured during very short pump cycles)

APPLICATIONS

Water level measurement in:

• rivers, streams, watercourses, natural and artificial channels
• groundwater wells and piezometers
• retention reservoirs, lakes, floodplains

Ideal for monitoring:

• in water level observation networks
• in areas prone to lightning strikes
• in channels and watercourses with long and flat embankments
