Aigner-powered electromagnetic flow meter.

Mô tả

Aigner-powered electromagnetic flow meters are widely used due to their minimal obstruction to fluid flow, reasonable cost, and high measurement accuracy. With no moving parts, electromagnetic flow meters are not affected by wear, helping reduce operating and maintenance costs. A wide range of electromagnetic flow meters is available with various liner materials, electrode options, and sizes, capable of measuring flow rates of many different types of conductive liquids.
Đặc điểm nguồn điện và kết nối:
– Diverse power sources: Usually supports a wide voltage range from 100 - 240V AC (mains) or 24V DC (Suitable for industrial control cabinets)
– Real–time response ability: Since there is no concern about battery saving, this line has an extremely high sampling rate, giving accurate measurement results almost instantly as soon as the flow rate changes.
– Rich output signals: Fully integrated with standard communication ports to send to the SCADA system
Technical specifications:
– Size: DN3 – DN3000 (1/8" – 120" according to ANSI/DIN standards)
– Accuracy: ± 0.5% of reading at flow rate ≥ 0.5m/s 0.1∼15m/s
– Structure: Compact/remote, standard cable length 10m, maximum 100m
– Protection rating: IP65, IP68 (submersible, remove type only)

– Functions: High and low alarms, system alarm, empty pipe alarm, self - diagnostics.
Key Characteristics: 
– Wide range of standard sizes from DN3 to DN3000
– High accuracy up to 0,2% available, supports bidirectional flow measurement capability
+ Independent of pressure, temperature, density, and viscosity of the fluid
– No moving parts, requiring minimal maintenance
– Supports data logging/ Bluetooth/ wireless communication
– Automatic power failure recording function (optional)
Benefits: 
– No feature limitations: Supports continuous operation of the backlit LCD display, allowing technicians to easily monitor parameters in low-light conditions.
– Control capability: Relays can be installed to automatically control pump or valve on/off operation based on flow rate thresholds.
– Component durability: Powered by the mains supply, the device does not experience performance degradation over time as occurs with weakening batteries.
Disadvantages:
– Fully dependent on the electrical infrastructure
– Electrical risks: Issues such as lightning surges or sudden voltage drops in the power grid may damage the converter.
– More complex installation requirements
– Electromagnetic interference: If installed near variable frequency drives (VFDs) or high-power motors, the measurement signal may be affected by interference unless proper shielding and grounding are applied.
