Description

Rotameters Supplied by HA Tradings

At HA Tradings, we supply precision rotameters, also known as variable area flow meters, from verified and trusted international manufacturers, offering reliable volumetric flow measurement for liquids and gases in industrial processes. Tailored for B2B bulk buyers, these rotameters provide accurate, low-maintenance solutions for monitoring and control in diverse applications, ensuring compliance and operational efficiency.

Key Specifications & Technical Standards

Our rotameters adhere to international standards such as ISO 5167, OIML R137, and EN 1359, guaranteeing high accuracy and durability. Available in glass, plastic, or all-metal tube designs, with sizes from 1/4″ to 4″ (DN6 to DN100) and flow capacities up to 1,000 m³/h for gases or 500 GPM for liquids at pressures to 100 bar and temperatures -40°C to +400°C. Floats made from stainless steel, glass, or PTFE for media compatibility, featuring tapered tubes with direct-reading scales calibrated for air/water equivalents. Accuracy ±1-2% FS over 10:1 turndown, with low pressure drop <2 mbar. Options include needle valves, alarms, and transmitters for 4-20 mA output. Safety features encompass armored shielding, explosion-proof enclosures (ATEX Zone 1), and over-range protection. Each unit undergoes factory calibration, leak testing, and certification by bodies like TÜV or NIST, compliant with UAE industrial flow measurement regulations.

Features & Benefits for Bulk/Industrial Buyers

Designed for high-volume industrial use, our rotameters incorporate simple mechanical operation that requires no external power, reducing installation costs by 30% and enabling easy visual monitoring. Variable area principle ensures linear response across ranges, minimizing errors in fluctuating flows. Bulk buyers benefit from customizable materials for corrosive or high-pressure environments, with all-metal versions offering 20+ year lifespans. Integrated alarms and switches automate shut-off for safety, while low-maintenance designs cut downtime. Scalable for manifold blocks in parallel systems, supporting large-scale deployments. Environmentally robust with no emissions, they align with ISO 50001 efficiency goals. Sourced from certified manufacturers, these rotameters provide consistent quality, extended warranties, and bulk pricing for optimized ROI in process control and utilities.

Applications

Rotameters from HA Tradings are versatile for numerous industrial applications. In chemical processing, they measure corrosive fluids in reactors and mixing vessels. Petrochemical plants utilize them for gas analyzers and purge flows in distillation units. Pharmaceutical facilities integrate glass-tube models for ultrapure water and solvent metering. Food and beverage operations employ them for cooling circuits and CIP systems. Power generation relies on metal rotameters for fuel gas lines and steam monitoring. Water treatment plants use them for brine and chemical dosing. Their visual indication suits laboratories for R&D, while armored designs fit harsh environments like mining and offshore platforms, adhering to seismic, fire safety, and NACE MR0175 standards.
