Foxboro 845-EP1H1G1HNNAANMSPFASENNBN Vortex Flow Transmitter

Product Description

The 845-EP1H1G1HNNAANMSPFASENNBN is a full ordering code variant of Foxboro 845 series vortex flowmeter by Schneider Electric. It is a precision volumetric flow instrument for gas, steam and liquid media, adopting vortex shedding principle. This long part number defines the body material, process connection, size, electronics, output, communication, certification and sensor configuration. It outputs 4-20mA analog signal with HART protocol, and supports pulse output for flow totalization. It is widely used in petrochemical, power and oil & gas process measurement.

Features

• Vortex shedding measurement principle, no moving internal parts, low maintenance
• 4-20mA + HART 7 communication, optional pulse frequency output
• Wide turndown ratio, suitable for saturated steam, compressed air, liquid and process gas
• Available with ATEX / IECEx explosion-proof certification for hazardous areas
• On-board LCD display for instantaneous flow, totalizer and diagnostic data
• Resistant to vibration and temperature fluctuation, stable long-term measurement
• Configurable via HART handheld communicator or FDT/DTM software
• Flange connection, customizable material for corrosive process media

Application Scenarios

• Steam flow measurement for boiler and power plant auxiliary systems
• Petrochemical plant gas, compressed air and process liquid flow monitoring
• Oil & gas, refinery and chemical hazardous zone flow metering
• Energy management, heat balance and consumption totalization
• Integration with DCS / PLC system via HART and 4-20mA signal
