Information About EC350
The EC350 is the latest generation of electronic volume correctors from Honeywell, building on over 40 years of experience from legacy Mini-Max® and Mini-AT models. The device accurately converts gas volume at operating conditions to reference conditions using integrated pressure and temperature sensors and supports AGA and NX-19 calculation standards. The EC350 is available in meter-, rotary-, or wall-mount configurations and supports up to two pressure inputs with a plug-and-play digital transducer. Featuring a multi-line LCD, internal lithium battery (up to 10 years), optional cellular modem, RS232/485 ports, and support for AMR and Invisiconnect IP calling, it is ideal for utilities looking to reduce ownership costs and simplify field servicing.
Key Features:
- Flexible Mounting Options: Available in UMB-, rotary-, and wall-mount configurations for a range of meter installations.
- Accurate Volume Correction: Uses AGA-7, AGA-8 (gross methods 1 & 2, detailed), and NX-19 for precise correction.
- Advanced Digital Pressure Transducer: Plug-and-play design for ease of service and reduced calibration time.
- 10-Year Battery Life: Lithium-powered system minimizes site visits and maintenance costs.
- Integrated Communications: Internal cellular modem, RS232/485, and IrDA configuration ports for flexible integration.
- Audit Trail and Diagnostics: Offers up to five independent logs and detailed status alerts to support compliance and preventive maintenance.
- Wide Operating Range: Works from –40°C to +77°C, with ±0.1% accuracy on pressure and temperature readings.
- AMR and SCADA Ready: Compatible with Itron, Sensus, Aclara, and other remote reading platforms.
- Field Serviceable Design: Enclosure and electronics optimized for in-field maintenance and part replacement.
- Certified for Safety and Performance: Meets CSA Class I Div 1 & 2, and IEC-Ex explosion-proof standards.
The EC350 simplifies gas volume correction and remote monitoring, reducing operating costs while enhancing data reliability for billing and regulatory compliance.
