The irrigation Electromagnetic Flow Meter is designed for environments where both mains power and field battery operation are required. It supports AC220V/DC24V and built-in lithium battery supply, ensuring continuous measurement and stable data recording even in remote areas without a power grid.This model is ideal for agricultural irrigation, water resource management, rural water supply, and outdoor flow monitoring.
1.Dual Power Supply:
Operates with AC220V/DC24V mains power or switches automatically to an internal lithium battery when grid power is unavailable.2.Low Power Consumption:
In battery mode, it can continuously operate for 3–5 years, depending on configuration and usage.3.Remote Communication Options:
Supports RS485, LoRa, and NB-IoT for remote data transmission and flow monitoring.4.IP68 Protection:
Fully sealed design for outdoor and underground installations, resistant to rain, flooding, and harsh field conditions.5.Data Security:
Internal memory ensures totalized flow data is retained during power failure.6.Easy Installation:
Compact one-piece structure, available in flange or clamp connection, suitable for quick field setup.
Flow measurement in channels, pipelines, sprinklers, and drip irrigation systems.
Reservoir discharge monitoring, groundwater abstraction tracking.
Village water networks and zone metering applications.
Flow measurement in remote or unmanned areas.
