Flow meters are critical instruments used to measure the flow rate, volume, or mass of fluids in industrial, municipal, and commercial systems. With the increasing demand for automation, accuracy, and energy efficiency, modern flow meters must operate reliably across a wide range of conditions — from clean water to corrosive chemicals, high-viscosity fluids, steam, gases, and slurry.
The flow meters in this collection — Coriolis, Electromagnetic, Gas Turbine, Liquid Turbine, and Vortex — represent a complete portfolio suitable for nearly every flow-measurement requirement. These instruments offer high precision, digital communication, explosion-proof options, IP67/IP68 protection, and advanced electronics to ensure accurate and stable performance even in harsh environments.
From water treatment and chemical processing to steam measurement and gas metering, these flow meters integrate seamlessly with PLCs, HMIs, DCS, and IoT monitoring systems to support automated control and operational optimization.
What is a Flow Meter?
A flow meter is a device that measures the flow rate of a fluid (liquid, gas, or steam) as it moves through a pipe. Different technologies are used depending on the type of fluid, accuracy required, and process conditions.
1. Coriolis Mass Flow Meter (GCF-1000 Series)
Measures mass flow directly using the Coriolis force principle.
Also provides density, temperature, concentration, and volume flow simultaneously.
Key technologies include:
DSP closed-loop processing
Self-adaptive drive circuits
Multi-parameter measurement
Ultra-stable zero point
Tube geometries: U-type, V-type, S-type, Triangle-type
2. Electromagnetic Flow Meter (GEF-1000 Series)
Ideal for conductive liquids (>20 μS/cm).
Uses Faraday’s Law of Electromagnetic Induction.
Has no moving parts and provides extremely stable, drift-free measurement.
Features include:
PTFE lining >3mm
Pure copper coils (99.999%)
IP68 waterproofing
Bi-directional measurement
Excellent small-flow performance (down to 0.01 m³/h)
3. Gas Turbine Flow Meter
Uses a high-speed turbine rotor whose speed is proportional to gas flow.
Suitable for air, nitrogen, natural gas, and compressed gases.
Offers wide ranges up to 650–13,000 m³/h depending on pipe size.
4. Liquid Turbine Flow Meter (GTF-1000L Series)
Ideal for clean, low-viscosity liquids.
Provides high accuracy (up to ±0.2%) and fast response.
Available in threaded, flange, and sanitary connections.
5. Vortex Flow Meter (GVF-1000 Series)
Measures liquids, gases, and steam using the vortex shedding principle.
Highly suitable for saturated steam, compressed air, and industrial gases.
Available in wafer and flange types with remote or integrated electronics.
