M-Series Positive Displacement Flowmeters: Precision Engineered for Demanding Liquid Applications

When accuracy, durability, and versatility matter in liquid metering, the M-Series Positive Displacement Flowmeter stands apart. Designed for seamless integration into transfer and process control systems, these meters deliver unmatched reliability for industries ranging from fuel distribution to chemical processing. Discover how the M-Series’ innovative engineering solves your toughest flow measurement challenges.

How It Works: Precision by Design

The M-Series employs a robust, no-compromise mechanical design:

Synchronized Rotor System: Two-blade displacement rotors and a central blocking rotor rotate within three cylindrical bores with zero metal-to-metal contact, ensuring minimal wear and long-term accuracy.

Continuous Capillary Seal: The blocking rotor creates a leak-proof barrier between unmetered upstream and metered downstream product, eliminating slippage even with low-viscosity fluids.

Timing Gear Mechanism: With the blocking rotor gear rotating at half the RPM of the displacement rotors, synchronization is maintained for consistent, repeatable measurements (0.05% repeatability).

Key Features & Benefits

Built for Tough Environments:

Max Pressure: 10 Bar | Max Temperature: 120°C

Corrosion-resistant housing and bearings for harsh chemical or fuel applications.

High Accuracy Across Flow Rates:

Models like the M-150-1 handle up to 3,000 L/min at 25 Bar, while the M-40-1 starts at 25 L/min (see full specs below).

Easy Integration & Customization:

Process Connection Options: ANSI, NPT, BSPF or other standards as requested

Units: Liter, US Gallon, IMP Gallon

Strainer Mesh: 80-mesh for diesel, 40-mesh for gasoline (prevents clogging).

Low Maintenance: No exposed electrical components and a self-lubricating design reduce downtime.

Ideal Applications
