Main Functions

Signal acquisition & conditioning: Receives tiny flow‑induced voltage signal from remote electromagnetic flow sensor, filters noise and amplifies raw measuring signal.
Flow calculation: Computes volumetric flow rate, forward / reverse flow, cumulative totalizer value based on sensor input.

ABB WaterMaster Select FES121 Remote‑Mount Electromagnetic Flow Converter

Standard analog output: Galvanically isolated 4‑20 mA HART output, transmits real‑time flow value to PLC, DCS or recording instruments
Pulse / frequency digital output: Open‑collector isolated pulse signal for totalized flow counting; frequency output proportional to instantaneous flow rate.
Totalizer function: Stores forward total, reverse total and net flow total; supports totalizer reset.
Diagnostic & alarm function: Detects empty‑pipe condition, electrode fault, signal abnormal, power supply failure; outputs alarm status via digital channel.
HART digital communication: Supports remote parameter configuration, reading process data and fault diagnosis via HART hand‑held communicator or upper system.
Parameter configuration: Supports setup of pipe diameter, fluid conductivity, filter time, output scaling, alarm threshold.More products: www.plcva.com
Harsh‑site adaptability: IP67 enclosure rating, wide operating temperature range, suitable for field cabinet or outdoor remote installation.
