LABTECH PROFLOW 5000 flow meter installed on pipeline

Comprehensive Flow Measurement Technology

Labtech Electronics offers a complete range of flow meters designed to deliver accurate, reliable measurement across a wide spectrum of process fluids and operating conditions. With over 27 years of engineering expertise, our flow measurement instruments are trusted by water utilities, chemical plants, pharmaceutical manufacturers, and industrial facilities across India and globally.

From electromagnetic flow meters for conductive liquids to ultrasonic and Coriolis meters for custody transfer, every Labtech flow meter is built to international standards including MID, OIML, and IS 6206, and is available with ATEX/IECEx certification for hazardous area installations.

Flow Meter Technologies

Electromagnetic Flow Meters

Ideal for conductive liquids including water, wastewater, slurries, and chemical solutions. No moving parts, zero pressure drop, and bi-directional measurement capability.

Accuracy: ±0.3% of reading
Pipe sizes: DN10 to DN2000
Output: 4–20mA, HART, PROFIBUS, Modbus
Protection: IP68 / IP67
Liner: PTFE, Hard Rubber, Polyurethane

Ultrasonic Flow Meters

Non-invasive clamp-on and inline ultrasonic meters for clean liquids and gases. No pipe cutting required for clamp-on variants — ideal for retrofits and temporary measurement.

Accuracy: ±1% of reading (clamp-on), ±0.5% (inline)
Pipe sizes: DN15 to DN6000 (clamp-on)
Output: 4–20mA, RS485, Modbus RTU
Temperature range: -40°C to +160°C
Battery or mains powered options

Coriolis Mass Flow Meters

Direct mass flow measurement for liquids and gases with simultaneous density and temperature measurement. Highest accuracy for custody transfer and batch dosing applications.

Accuracy: ±0.1% of reading (mass flow)
Density accuracy: ±0.0005 g/cm³
Pipe sizes: DN4 to DN200
Output: 4–20mA, HART, Foundation Fieldbus
ATEX/IECEx certified variants available

Vortex Flow Meters

Robust vortex shedding meters for steam, gas, and liquid applications. Wide turndown ratio and no moving parts make them ideal for high-temperature and high-pressure service.

Accuracy: ±1% of reading (liquids/gas), ±1.5% (steam)
Pipe sizes: DN15 to DN300
Process temperature: up to 350°C
Output: 4–20mA, HART, pulse
Integrated temperature/pressure compensation available

Differential Pressure Flow Meters

Orifice plates, venturi tubes, and annubar primaries for steam, gas, and liquid measurement. Cost-effective solution for large pipe diameters and high-pressure applications.

Pipe sizes: DN25 to DN2000+
Suitable for steam, gas, and liquids
Customised primary elements to order
Paired with Labtech DP transmitters
Compliant with ISO 5167

Open Channel Flow Meters

Ultrasonic level-based flow measurement for rivers, canals, irrigation channels, and wastewater effluent. Non-contact measurement with no flow obstruction.

Flume types: Parshall, V-notch, rectangular weir
Measurement range: 0.1 m/s to 10 m/s
Output: 4–20mA, RS485, data logger
IP68 submersible sensor option
Telemetry and SCADA integration ready
