Rotameters (Universal)
Metal Tube Rotameter (Variable Area Flow Meter)
-
IOTAFLOW Metal Tube Rotameter – High-Pressure Variable Area Flow Meter. - Durable metal tube rotameter for process water, steam, compressed air, and chemicals.
- Made in India for reliable industrial and utility flow measurement.
The IOTAFLOW Metal Tube Rotameter Series delivers accurate, reliable measurement of liquids, gases, and steam in demanding industrial environments.
Built with a robust SS316 stainless steel body (optional PTFE lining) and available in multiple connection types including flanged, sanitary, and tri-clamp, these variable area flow meters are designed for high pressure (up to 100 bar) and high temperature (up to 300°C) service.
With magnetic coupling indication, optional 4–20 mA transmitters, and switch outputs, they ensure safe operation without leakage risk.
Ideal for utilities, chemical plants, food & beverage, oil & gas, and process industries requiring dependable flow monitoring.
For dairy, food and pharmaceutical lines, the sanitary and tri-clamp versions fit directly into hygienic stainless steel pipework built with dairy and sanitary fittings, keeping the whole line easy to clean.
Applications
• Chemical processing — Monitoring flows of acids, bases, solvents, and reagents in chemical plants and laboratories.
• Oil and gas sectors — Measuring fuels, lubricants, condensate, and vented gases under high temperature and high-pressure conditions.
• High-pressure offshore systems — Used on oil platforms for drilling mud, hydraulic fluids, and high-temperature coolant metering.
Utilities & Water Treatment
• Water and wastewater plants — Measuring raw and treated water, chemical dosing flows, and air/gas lines during treatment.
• Power generation — Monitoring boiler feedwater, cooling fluid, and steam flows in thermal and renewable power stations.
Pharmaceutical, Food & Beverage
• Pharma manufacturing — Measuring flows of pure water, solvents, reagents in sterile plant environments.
• Food and beverage industry — Used for ingredient dosing, syrup and oil flow control, and sanitary process monitoring.
Specialty & Advanced Applications
• Research & development — Utility in pilot plants, R&D flow validation, safely handling variable or corrosive fluids.
• Transport systems — Used to regulate the flow of LNG vapors during regasification, especially valuable in loading/unloading operations.
