Aplisens Electromagnetic Flowmeter PEM-500 Series

Introduction – Aplisens Electromagnetic Flowmeter PEM-500 Series

The Aplisens Electromagnetic Flowmeter PEM-500 Series is designed for accurate measurement of conductive liquids with a minimum conductivity of 5 µS/cm. Operating on the electromagnetic induction principle, it provides precise and stable readings of flow rate and total volume in both directions. Its compact, sealed design with no moving parts ensures maintenance-free operation and undisturbed flow of the measured medium.

Engineered for versatility, the PEM-500 Series is suitable for pure, viscous, and chemically aggressive liquids. It is widely used in water and wastewater treatment, chemical processing, food production, and thermal energy plants. The instrument’s robust construction with optional IP68 protection allows underground or flooded installations, making it ideal for challenging industrial environments.

Configuration and communication are handled via the RS-485 interface with Modbus RTU protocol, enabling remote setup, diagnostics, and integration with automation systems. The flowmeter can be easily programmed for empty-pipe detection, low-flow alarms, or event recording. It also supports external visualization through an optional HMI panel, allowing real-time monitoring and configuration.

The Aplisens Electromagnetic Flowmeter PEM-500 Series, distributed by Dubai Sensor, combines reliability, accuracy, and flexibility, meeting the high standards demanded by industrial users across the UAE and MENA region.

Installation, Commissioning & Maintenance

The PEM-500 Series flowmeter is flanged for direct pipeline installation. For most configurations, a 5 × DN upstream and 3 × DN downstream straight pipe length is recommended, except for the CP version, which allows installation without straight sections.

Electrical connections are factory-terminated for convenience, ensuring safe and reliable operation. Optional PP-PEM junction boxes (IP67) simplify wiring in the field. The meter requires no routine recalibration due to its non-mechanical measuring principle, and the optional remote HMI panel facilitates configuration, diagnostics, and real-time flow monitoring.
