Is your research or process hampered by flow data that isn't实时, or by meters that can't communicate with your modern control systems? Moving beyond simple totalization, today's labs and plants demand intelligent flow data for analysis, automation, and quality assurance. The ABR-Birotor Flowmeter with electronic counter is a high-precision volumetric flow meter engineered to deliver exceptional mechanical metering combined with advanced digital connectivity for pipe sizes from DN15 to DN400.

Why Choose an Electronic Birotor Flowmeter? Solving Data Integration & Accuracy Challenges

Eliminate manual readings and integrate flow data directly into your workflows. This precision digital flowmeter solves critical pain points for modern facilities.

• Seamless Data Integration & Remote Monitoring: Unlike purely mechanical units, this ABR Birotor flowmeter with RS485 Modbus transforms precise volumetric measurements into actionable digital data. The electronic counter enables real-time flow monitoring via RS485 Modbus communication and (4-20)mA analog output, allowing for seamless integration with PLCs, SCADA, and data acquisition systems for remote control and process optimization.

• Unwavering Accuracy Across All Liquid Types: Achieve the highest level of confidence in your measurements. The proven double-rotor technology provides superior volumetric flow accuracy up to ±0.1% . This exceptional performance remains stable across an incredibly wide viscosity range (0 to 20,000 mPa.s), from low-friction solvents to highly viscous crude oils and polymers, eliminating the need for constant recalibration.

• Enhanced Process Control & Flexibility: The electronic counter for Birotor flowmeter does more than just count. It facilitates automatic unit conversion for international workflows and, when combined with stable density data, can perform mass conversion. This empowers you with versatile, intelligent data for better process decisions and quality documentation.

Key Features for Demanding Applications

Engineered for longevity and performance, this flowmeter offers:

• Superior Reliability: Proven double-casing design and self-lubricating rotors ensure a long service life with minimal wear.

• Low Pressure Loss: The uniform rotation of the dual rotors creates very low noise, vibration, and pressure drop across the meter.

• Easy Maintenance: Simple construction allows for straightforward servicing, reducing downtime.

• Global Compatibility: Outputs and unit conversions meet diverse international measurement standards.
