Aigner battery-powered electromagnetic flow meter

Mô tả

The Aigner battery-powered electromagnetic flow meter (AIGNER/D) is a flexible and accurate solution that operates independently of mains power, making it ideal for remote water supply systems, water treatment, and industrial flow measurement applications—especially where remote monitoring and automation integration are required. With long battery life and multiple communication options, it is well suited for modern measurement and control systems.
Technical Information:
– Battery: Uses 5 built-in 3.6 V lithium batteries, battery life ≈ 3–8 years depending on usage and device configuration.
– Size: DN10 – DN2000 (≈ 3/8″ – 80″)
– Velocity: 0.1 – 15 m/s
– Standard accuracy: approx. ±0.5% of measured value
– Higher accuracy option: ±0.2% (high accuracy) available upon request
– Fluid type: Measures conductive liquids only (conductivity > 5 μS/cm, or > 20 μS/cm for water)
– Operating temperature: Display/transmitter −20°C to +60°C; sensor up to +80°C – +150°C depending on liner material
– Protection class: IP65, IP68
– Output signal: 4–20 mA
Benefits:
– Operates independently without mains power
– Battery life: 3–8 years depending on workload and configuration
– High accuracy: ±0.2% to ±0.5% (depending on configuration)
– Modern communication connectivity: PLC/SCADA and IoT integration via RS-485, HART, GPRS/4G/5G
– Excellent protection: IP68 allows outdoor or submerged installation without risk of device damage
– Wide application environments: from clean water and wastewater to conductive chemicals (depending on material selection)
Disadvantages:
– Measures conductive liquids only; not suitable for oil or dry gas
– Higher initial investment compared to many mechanical or basic ultrasonic meters
– Proper pipeline design and calibration are required to achieve optimal accuracy
– Battery life may decrease significantly if GSM/GPRS data transmission is too frequent
