Design & Functionality

The flowmeter features a robust design with IP65 protection, ensuring durability in harsh industrial conditions. Its intelligent display system shows instantaneous flow, cumulative flow, and diagnostic alerts such as empty pipe detection and excitation faults. The membrane touch interface simplifies configuration and operation.

Total Crossed Beams

The electromagnetic sensing principle ensures full-bore measurement without obstruction. This allows uninterrupted fluid flow and eliminates pressure loss, making it highly efficient for continuous industrial processes.

Beam Pitch Options

Optimized internal calibration allows flexible adaptation to varying pipe diameters and flow ranges. This enhances compatibility across industries such as oil processing, wastewater treatment, and food-grade liquid handling systems.

Intrinsic Synchronism

The device maintains consistent signal synchronization between sensors and transmitters, ensuring stable data output even under fluctuating flow conditions. This improves accuracy and reduces measurement errors in dynamic environments.

Operational Advantages

The 4800 flowmeter supports multiple output configurations including analog, frequency, pulse, and alarm outputs, enabling seamless integration into automation and control systems. With optional RS232/RS485 and HART communication, it fits modern industrial IoT ecosystems. Its low maintenance design, absence of moving parts, and strong resistance to corrosion make it ideal for long-term deployment in process control industries.
