The RBHEF-LS Series is specifically designed for solid-liquid two-phase flows and high-concentration slurries. By integrating multi-frequency excitation and intelligent filtering, it perfectly solves the jitter and noise issues common in pulp and mining applications.The RBEF-LS High frequency slurry type Magnetic Flow Meter is special designed for the measurement of Process Media Type: Liquid, Suspended Solids / Slurries, pulp, paper pulp and pasty liquid. To achieve a stable measurement of slurry, 25Hz excitation frequency and latest noise-suppression methods are applied to reduce the flow noise effectively.
According to the characteristics of the medium, the slurry-type electromagnetic flowmeter adopts various technologies such as multi-frequency excitation, digital noise reduction, and new algorithm filtering. It perfectly solves the measurement problems of various concentration solid-liquid two-phase fluids such as pulp, mineral slurry, mud, coal-water slurry, and fruit pulp, achieving accurate measurement, stable data, and fast response.
The converter of this type flowmeter uses 25Hz ~ 50Hz high-frequency square wave excitation, so that effectively reduces the flow noise. It uses the latest signal processing technology and noise suppression algorithm to achieve a stable measurement, which means Zero-point stability, Low steady-state volatility and fast dynamic response. The sensor has abrasion-resistant lining, which is suitable for the flow measurement of solid-liquid suspension or inhomogeneous liquids. RBEF is mainly used for measuring the slurry of pulp, coal water slurry, mud (including micro particles) and cement slurry etc.
Multi-frequency slurry type Magnetic Flow Meter Features:
Noise Suppression: Advanced digital noise reduction algorithms ensure a stable reading even with high-solid content.

Multi-frequency slurry type Magnetic Flow Meter Applications:
Multi-frequency slurry type Magnetic Flow Meter is special designed for the measurement of pulp, paper pulp and pasty liquid.
1. Conventional Pulp Measurement: It is suitable for measuring pulp diluted with tap water.
When the pulp concentration is below 5%, it can accurately measure and ensure the stable operation of the papermaking production process.
2. Low - Conductivity Pulp Measurement: For pulp diluted with pure water, with a pulp conductivity of 1us/cm - 10us/cm and a concentration below 5%,
it is often used in the production of special papers such as insulating paper, meeting the high - precision measurement requirements of special
paper manufacturing.
Paper & Pulp: Conventional pulp (<10% concentration) and specialized insulating paper production.
Mining & Minerals: Accurate measurement of ore slurries and tailings.
Wastewater Treatment: Reliable data for sludge and solid-laden industrial water.
