Metlan Instruments today presents two complementary product lines built for mass flow measurement needs across gases and liquids: Mass Flow Meters / Controllers (MFM/MFC) for ultra-low dosing and stable regulation, and Coriolis Flow Meters for direct mass flow measurement with broad process adaptability.
1. Low-Flow Mass Flow Meter / Controller: measure and control at micro-flow ranges
Metlan’s mass flow controller series is designed for applications where “small flow errors become big problems,” such as laboratory instruments, gas panels, catalyst testing, micro-reactors, and precision dosing/skid integration. The product line supports mass flow measurement and (for controllers) closed-loop setpoint control to keep flow stable under changing operating conditions.
Key product highlights
- Ultra-low flow capability: measurement starting from 0.1 sccm (model/configuration dependent).
- Fast control response: controller response time < 1 second for real-time flow regulation.
- Multiple measurement principles available: Coriolis, Thermal Mass, and Differential Pressure options to match gas/liquid/steam and process demands.
- System-friendly integration: common signals and communications including 0–5V / 1–5V / 4–20mA, RS232/RS485, and MODBUS (with PROFIBUS indicated for certain configurations).
Low-flow product families (quick view)
- MTL20FE — Coriolis Low-Flow MFM/MFC (gas & liquid): turndown ratios listed as 50:1 (controller) and 100:1 (meter), with accuracy stated as ±0.5% F.S (gas) and ±0.25% F.S (liquid); max pressure up to 100 bar.
- MTL20FC — Differential Pressure Mass Flow (gas/liquid/steam): measuring range stated as 2 SCCM to 3000 SLM (configuration dependent), with display of instantaneous/cumulative flow plus pressure and temperature.
- MTL20FD — Thermal Gas Mass Flow (gas): measuring range stated as 02 SCCM to 6000 SLM (configuration dependent), designed for stability and anti-blockage via a tubular shunt approach.
2. Coriolis Flow Meters: direct mass flow with density and temperature insights
For customers seeking high confidence mass flow measurement, especially when fluid properties change, Metlan’s Coriolis mass flow meters measure mass flow directly using vibrating tube technology. The product line also highlights added process value from density (derived from vibration frequency) and temperature sensing, supporting richer diagnostics and derived calculations (such as volumetric flow).
Metlan also summarizes typical Coriolis performance expectations: liquid accuracy commonly ±0.1% to ±0.2% of reading, and gas accuracy commonly ±0.5% to ±1.0% of reading, with strong rangeability commonly up to 100:1 for liquids (figures dependent on model and conditions).
Coriolis product families highlighted on the page
- MTD-ACMW (W shape) / MTD-ACMC (C shape): accuracy options down to ±0.1% (configuration dependent), with temperature capabilities including split-type operation down to 200°C and up to +350°C, and max pressure listed up to 250 bar for these families.
- MASS series (MASS-A / MASS-L / MASS-C): positioned for advanced process measurement, low-flow & dosing, and cryogenic applications respectively; materials listed include 316L and Hastelloy C (others on request). The MASS-L low-flow/dosing line lists max pressure up to 875 bar.
Selecting the right product: a practical positioning
Metlan’s two lines are designed to be complementary:
- Choose Low-Flow MFM/MFC when your top priority is ultra-low flow stability and active control (setpoint regulation).
- Choose Coriolis Flow Meters when you need direct mass flow with strong adaptability and added density/temperature insight for process measurement.
Calibration and traceability
Metlan states that its flow meters are calibrated and assigned a unique serial number linked to calibration data for traceability.
Availability
Low-flow MFM/MFC and Coriolis flow meters are available through Metlan Instruments’ product pages with configuration options and quotation request pathways.
