i-Series sensors are high-precision ultrasonic sensors for measuring distance, level, empty space, and volume, for liquid media or bulk materials.
They are particularly suited to harsh environmental conditions. Their non-contact measurement technology prevents fouling and wear. Defined, pre-configured measurement ranges avoid complex programming.
i-Series Sensors can be connected to any PLC, data logger or acquisition system with an active mA input or HART communication protocol.
More specifically, they are commonly used in NivuFlow flowmeters from Nivus.
Applications
- Wastewater: pumping stations, overflow structures, clarification basins, screening facilities, etc.
- Drinking water: tank level measurement, water treatment
- Flowmetering using flumes, weirs or channels
- Tank volume measurement, container monitoring
- Irrigation systems, seawater desalination
- Flood protection: retention reservoirs, surface water
- Power generation: cooling systems, hydroelectric power plants
Main benefits
- High accuracy
- Settings and pre-programming for 3, 6, 10 and 15 m ranges
- Low power consumption (short measurement time, fast start-up time in standby mode); ideal for battery-powered systems
- Resistant to moisture, corrosion, and extreme temperature variations
- Degree of protection IP68
- Can be connected directly to a PLC
- Time- and space-saving, integrated transmitter
- Digital echo processing with automatic false echo suppression (DATEM process)
- Approval for potentially explosive areas Class I/Division 1/Zone 1 (Zone 0 optional)
