A2EN501-S00000

The Yokogawa A2EN501-S00000 is a complete, integrated Vortex Flowmeter from the YEWFLO E Series (often marked as models YF100, YF200, etc.). Unlike the sensor-only S2EN501 model, this unit is a one-piece flowmeter where the sensor and the converter (transmitter) are housed together in a single, compact enclosure.

Parameter Specification Details / Notes
Model Number A2EN501-S00000 A2EN501: Base model for an integrated vortex flowmeter.
-S00000: This suffix indicates a standard configuration with default options for materials, flange, and output.
Product Line Yokogawa YEWFLO E Series (e.g., YF100, YF200 models)
Device Type Integrated In-line Vortex Flowmeter Sensor and transmitter in one unit.
Nominal Pipe Size 1 inch (25 mm) The model number 501 typically corresponds to a 1" line size.
Process Connection Flanged The specific flange standard (e.g., ANSI, JIS) and pressure class (e.g., 150lb) are defined by the full order code. The -S00000 suggests a common default like ANSI 150lb.
Body Material Stainless Steel (typically SUS316) Standard material for most applications.
Output Signal 4 to 20 mA DC, 2-wire with HART protocol digital communication.
Power Supply 10.5 to 42 V DC (standard for 2-wire 4-20mA loop)
Fluids Liquid, Gas, Steam
Flow Velocity Range Liquid: 0.3 ~ 9 m/s
Gas/Steam: 4 ~ 90 m/s
Accuracy ±1.0% of rate (typical for liquid)
±1.5% of rate (typical for gas/steam)
Temperature Range Standard: -40 to +260 °C (-40 to +500 °F)
High-Temp Option: Up to +455 °C (+851 °F)
Pressure Rating Depends on Flange Rating (e.g., ANSI 150#: ~20 bar @ 100°C) Must be confirmed from nameplate or order documents.
Ambient Temperature -40 to +85 °C (-40 to +185 °F) (for transmitter)
Protection Rating IP67 / NEMA 4X Weatherproof and dust-tight.
Local Display Optional (likely on most modern units) LCD display for readout and configuration.
