📊 External Control (4-20mA Current Loop & Hall-Effect Water Meter Pulse Multiplication)

Smart Solenoid Pump 4-20mA & Pulse Control Calculator

Model proportional pacing algorithms driven by external 4-20mA flow signals or pulsed contact water meters ($1 ext{ pulse / gallon}$): calculate pulse multiplication ($1:N$) and division ($N:1$) modes, maintain exact chemical PPM concentrations during fluctuating municipal flows, and water quality yields.
