Split-type Electromagnetic Flowmeter
Product Overview
The electromagnetic flowmeter consists of a sensor and a converter. The sensor is installed in the pipeline, while the converter is mounted in an instrument room or near the sensor for easy access, typically at a distance of tens to hundreds of meters. The converter amplifies, processes, and calculates the flow signal to display instantaneous flow, cumulative flow, and output pulse or analog current signals for fluid flow measurement and control. Equipped with an intelligent converter, it not only provides measurement and display functions but also supports remote data transmission, wireless control, alarms, and more.
Performance Features
- Simple structure with no moving parts or flow-obstructing throttling components in the measurement tube.
- Capable of measuring dirty, corrosive, or solid-liquid two-phase flow media.
- Unaffected by the temperature, viscosity, density, or conductivity (within a certain range) of the measured medium during operation.
- Output is proportional to the average flow velocity of the medium, independent of flow state (laminar or turbulent) under symmetric distribution.
- Rapid response with no mechanical inertia; measures instantaneous pulsating flow and bidirectional flow (forward/reverse).
- Wide selection of industrial-grade flowmeter diameters.
- Self-check and self-diagnosis functions.
- On-site range adjustment based on user requirements.
