What We Offer:
We specialize in a comprehensive portfolio of flow measurement technologies:
Below are some of our core products details.
Thermal Mass Flow Meter
- Wide Measuring Range with Ultra-Low Flow Capability. Our thermal mass flow meters feature an exceptionally wide turndown ratio of 2500:1, enabling accurate measurement from as low as 0.1 Nm/s up to 250 Nm/s.
- Integrated Chip-based Sensors. The integrated chip-based design supports long-term stability and measurement precision.
- Advanced Full-Digital Signal Processing. Full-digital processing helps deliver higher accuracy, improved zero-point stability and long-term drift resistance.
- Intelligent Sensor Diagnostics. Built-in diagnostics can detect contamination or overheating before it affects measurement accuracy.
Bi-rotor Positive Displacement Flow Meter
The bi-rotor positive displacement flow meters are used in demanding applications requiring accuracy, long life and ruggedness. Two simple rotors with no metal-to-metal contact are the only moving parts in the measuring chamber. They are suitable for gasoline, LPG, kerosene, light diesel oil, crude oil, heavy fuel oil and other high-viscosity liquids.
- High accuracy up to +/-0.1%. High process pressure up to 110 bar (1595 psi).
- Extremely long service life. Economical low maintenance.
- No sliding wear parts. No oscillating, reciprocating or sliding parts that disturb balanced rotary operation.
- Stable running with low voice. Good anti-interference performance and long service life.
- Strong applicability. Suitable for viscosity changes.
Coriolis Mass Flow Meter
- High accuracy up to +/-0.1%, good reliability. Coriolis mass flowmeters provide mass flow, density and temperature measurement performance for demanding process conditions.
- Good zero-stability and anti-interference performance. Low resistance and low pressure loss improve measurement accuracy and support complex field conditions.
- No moving parts, no maintenance required. A stable measuring tube design reduces routine mechanical wear.
- Multiple digital communication including Hart. Outputs can include 4-20 mA, pulse, Modbus RTU/RS485 and HART.
Low Flow Mass Flow Meter / Controller
- Ultra-Low Flow Detection with High Accuracy. Designed for precise control of micro to low flow rates, our meters and controllers measure from as low as 0.1 sccm.
- Multi-Fluid, Multi-Range, and Multi-Principle Flexibility. Sensor principles include Coriolis, thermal mass and differential pressure.
- Fast Response and Stable Control. A short control response time supports real-time flow regulation.
- Compact Design for Easy Integration. Compact modular bodies simplify integration into analytical instruments, automated systems and compact gas panels.
Certified Quality & Calibration
We are ISO 9001, CE, SIL2 and others certified, with each flow meter calibrated using equipment traceable to the National Institute of Metrology. Please check our
certifications. Every unit includes a unique serial number and full calibration records. Whether from our own production lines or trusted partners, all products meet strict precision and traceability requirements.
Our Activities
Metlan Instrument actively participates in various domestic and international exhibitions and technical seminars, sharing the latest technologies and solutions with industry experts and clients. These events not only enhance our brand influence but also foster deeper collaboration with customers, driving technological innovation and product optimization.
