Liquid Controls M7 Class 1 2 in. Flanged 100 GPM Meters

Liquid Controls M7 Class 1 2 in. Flanged 100 GPM Meters

The Liquid Controls M7 Series 2-inch flanged flow meter is a high-accuracy positive displacement meter engineered for precise measurement of petroleum-based and industrial liquids. Designed with a rotary motion measuring chamber that eliminates metal-to-metal contact, this meter delivers sustained accuracy, reduced wear, and extended service life with minimal recalibration requirements. Its right-angle configuration supports flexible installation options, while compliance with NIST and International Weights and Measures standards ensures suitability for custody transfer and other demanding applications. With a wide operating range for temperature and viscosity, the M7 Series provides consistent, reliable performance across a broad spectrum of fluids and operating conditions.

Features

• Sustained Measurement Accuracy: Non-contact internal measuring components minimize wear, preserving accuracy over time and reducing maintenance requirements.
• Wide Temperature and Viscosity Range: Accurately meters fluids from extremely low to very high viscosities and performs reliably in harsh temperature environments.
• High Pressure Rating: Rated for operating pressures up to 150 PSI, making it suitable for demanding industrial and commercial systems.
• Flexible Installation Design: Right-angle configuration with stock or custom elbows and fittings allows adaptable mounting in space-constrained installations.
• Custody Transfer Compliance: Meets NIST and International Weights and Measures accuracy requirements for regulated measurement applications.
