flow meters

Selecting the right flow meter is a critical decision that impacts operational efficiency and bottom-line costs. Two of the most common technologies in our lineup are the RBCM Coriolis Mass Flow Meter and the RBVF Vortex Flow Meter . While both are essential tools, they serve very different purposes. RBCM Coriolis Mass Flow Meter RBCM Coriolis : The Gold Standard for Precision The RBCM series utilizes the Coriolis effect to measure mass flow directly. Unlike volumetric meters , mass measurement is unaffected by changes in temperature, pressure, or viscosity. Best For: Pharmaceuticals, oil and gas custody transfer , and chemical blending. Key Advantage: It doesn't just measure flow; it provides real-time density and temperature data. Its high accuracy (up to ±0.1%) ensures that every drop of high-value fluid is accounted for. RBVF Vortex : The Steam and Utility Specialist The RBVF series operates by detecting vortices shed behind a bluff body . It is the "workhorse" of i...

 In modern water resource management, monitoring flow in open channels and partially filled pipes has always been a technical challenge. Traditional weir and flume methods , while reliable, often face high construction costs, head loss, and sedimentation issues. The RBDOF Series Doppler Ultrasonic Flowmeter represents a significant shift toward more efficient, maintenance-free measurement. The RBDOF Series Doppler Ultrasonic Flowmeter The Core Technology: Precision through the Doppler Effect The RBDOF operates on the Doppler effect principle: a probe emits ultrasonic beams into the fluid. These waves hit bubbles or suspended particles—which move at the same speed as the fluid—causing a frequency shift. By measuring this shift, the system calculates the true average velocity. Unlike clean-water ultrasonic meters, the RBDOF thrives in "real-world" water containing silt or air, making it ideal for municipal and agricultural use. Three Competitive Advantages of RBDOF ...

Measuring flow in gravity sewers, storm drains, or industrial effluent lines is challenging because pipes rarely run full. Traditional solutions like weirs , flumes , or siphons require expensive concrete work, take up space, and need constant cleaning. How to Measure Flow in Partially Filled Pipes Accurately The RBEF-P Partially Filled Pipe Electromagnetic Flow Meter from R&B Instrument Inc. offers a smarter, cost‑effective alternative. How it works It uses the velocity‑area method : an electromagnetic sensor measures flow velocity, and a high‑precision level gauge measures liquid height. The meter then calculates real‑time flow rate and totalized volume. Just input the pipe inner diameter. Why choose RBEF-P ? - Wide level range – accurate from 10% to 100% full pipe (accuracy ±2.5% FS) - Triple electrodes at 10%, 30%, and 50% of pipe diameter – the meter automatically uses the best signal above the liquid surface, avoiding oil or floating grease - No moving parts – unaffected by...

Introduction In industrial process control, measuring the flow of slurries —whether it's mining pulp , paper stock , or chemical waste —is notoriously difficult. Most engineers struggle with "jumping" signals and inconsistent readings. The culprit? Slurry Noise . Today, we explore how Multi-frequency Magmeters are revolutionizing this field by delivering rock-solid stability where others fail. Slurry Flow Measurement The Problem: Why Traditional Magmeters Fail in Slurry Standard electromagnetic flow meters typically use low-frequency excitation. When solid particles in the slurry collide with the sensors' electrodes, they generate massive electrochemical noise spikes. To a standard converter, this noise is indistinguishable from the flow signal, leading to erratic data that makes precise process control impossible. The Solution: RBHEF-LS Multi-frequency Technology The RBHEF-LS Series by RB Flowmeter is engineered specifically for these harsh environments. By emplo...

The Hidden Drain on Mining Profits In the high-stakes environment of gold and copper processing, abrasive slurry is a silent profit killer. For many mining plants, the constant "sandblasting" effect of solid particles means standard flow meters fail every 3 to 6 months. One major gold processing plant reported that these frequent failures weren't just a maintenance headache—they were a financial disaster. Each production line was losing approximately $150,000 annually in lost output, plus $20,000 in hardware replacement costs. The RB Flowmeter Intervention: Engineering for Longevity RB Flowmeter stepped in with a customized version of the RBHEF-LS Electromagnetic Flowmeter , specifically configured for high-abrasion hydrocyclone feed lines. The solution centered on three "Hardcore" technical advantages: • Advanced Material Synergy: We utilized a robust Polyurethane liner , which provides the necessary toughness to withstand high-velocity abrasive particles. ...
