Electromagnetic flowmeter EFM-115

Precise Flow Measurement for Conductive Liquids

The EFM-115 Electromagnetic Flowmeter delivers continuous and accurate flow measurement for electrically conductive liquids. Industries use this device to monitor flow in pipelines, process systems, and liquid transport applications.

The flowmeter measures both positive and negative flow directions. Operators can track forward and reverse flow conditions without additional sensors. This capability improves monitoring accuracy in industrial processes.

The system supports applications such as flow measurement, dosing, mixing, and liquid registration. Many industries rely on electromagnetic flowmeters because they provide stable and highly accurate measurements.

Measurement Based on Lorentz Law

The EFM-115 operates according to the Lorentz electromagnetic principle. When conductive liquid moves through a magnetic field, the system generates an electrical voltage.

The sensor detects this voltage and converts it into a flow rate signal. The control unit processes the signal and calculates the actual flow velocity and volume.

This measurement method ensures reliable results because it avoids mechanical moving parts. Consequently, the sensor maintains consistent accuracy over long operating periods.

Robust Industrial Construction

The EFM-115 features a durable sensor and transmitter housing designed for demanding industrial environments. The robust construction protects internal components from mechanical stress and environmental conditions.

The sensor supports flanged process connections from DN 15 to DN 200 mm, which allows installation in many pipeline sizes. Engineers can also convert the system from a compact version to a remote installation when required.

The flow tube uses stainless steel construction with carbon steel flanges, which improves strength and corrosion resistance. The internal liner uses hard rubber, which provides chemical resistance and stable performance in liquid media.

High Accuracy and Reliable Flow Monitoring

The EFM-115 provides measurement accuracy of 0.3% of the reading within the operating range. This high precision allows operators to monitor industrial processes with confidence.

The system supports flow velocities between 0.3 m/s and 12 m/s. In addition, the device includes adjustable low-flow rejection to eliminate measurement noise during very low flow conditions.

The flowmeter automatically performs zero-point calibration, which ensures stable performance even when flow conditions change.

Advanced Control and Communication Features

The control unit includes a backlit OLED display that shows real-time flow data and system information. Operators can easily read measurements and configure system parameters.

The device supports several industrial output signals. These include 4–20 mA analog output, frequency output, relay outputs, and RS-485 Modbus RTU communication.

The system also includes a built-in data logger capable of storing flow data for up to four months. This feature allows operators to review historical flow performance.

With durable construction, precise measurement technology, and advanced monitoring capabilities, the EFM-115 provides a reliable solution for industrial liquid flow measurement.
