An intrinsically safe explosion-proof turbine flowmeter measures liquid flow accurately in hazardous areas where flammable gases, vapors, or dust may exist. It combines a turbine sensor with intrinsically safe electronics and, if needed, an explosion-proof housing. Liquid flow rotates a low-inertia turbine. A magnetic pickup detects blade movement and sends pulses proportional to flow rate. The signal travels to a safe-area display, PLC, or DCS through an isolated barrier or galvanic isolator.

The meter often carries Ex ia IIC T4/T6 certification. Its energy, voltage, and current remain below ignition limits even during faults. Wetted parts are usually stainless steel, with durable bearings and precision machining for stable results. Stainless steel bodies and tungsten carbide bearings resist corrosion and wear. Outputs include pulse, 4-20 mA, HART, and RS485 for modern control systems.

Applications include oil and gas, petrochemical, chemical, pharmaceutical, and paint production. It measures solvents, fuels, hydraulic oils, and other low-viscosity liquids. The meter suits both custody transfer and process monitoring. Correct installation needs straight pipe runs, grounding, and approved safety barriers. Filtration and regular calibration help maintain accuracy and protect the turbine from debris. With proper barriers, it meets ATEX and IECEx requirements.

By combining intrinsic safety, explosion-proof protection, and precise turbine measurement, this flowmeter delivers reliable performance in demanding industrial environments.
