Product Description

Product Overview

The RBBF is an inline, flanged transit-time ultrasonic flow meter for industrial water and process liquids. Every unit leaves the factory calibrated, so no field setup is required, and the full-bore design has no moving parts and zero pressure loss.

Bi-directional measurement with high resolution, up to 2 GB of event logging and IP68 rating make the RBBF suitable for flooded pits, plant utilities and custody-transfer style monitoring.

Frequently Asked Questions

How accurate is the RBBF flow meter?

The RBBF offers Factory calibrated accuracy, verified through our ISO 9001-managed factory calibration process.

What pipe sizes can the RBBF accommodate?

The RBBF is available for pipe sizes from DN15 ~ DN1000, supporting a wide range of industrial flows.

Which output signals does the RBBF support?

The RBBF supports RS485 Modbus RTU, 4-20mA, pulse, M-Bus (relay/RS232/datalogger optional) output for integration with your control system.

How do I choose between electromagnetic, ultrasonic, and vortex flow meters?

Selection depends on fluid conductivity, pipe size, temperature, and accuracy needs. Electromagnetic meters suit conductive liquids, ultrasonic meters suit large pipes and clean liquids, and vortex meters handle steam, gas, and liquids. Contact R&B Instrument Inc. engineers for a recommendation.
