How It Works

A municipal water system moves water from source to distribution through a series of monitored and controlled stages.

1
Well Pump

Extracts water from underground aquifer and fills storage tank

Signals

  • • Motor V/A/kW/Hz (VFD)
  • • HOA/Run/Fault status
  • • Start/Stop command
  • • 4-20mA downhole water level sensor

DV8 Displays

Run status, fault detection, motor diagnostics

Alarm Examples

Fault condition, overcurrent, no-flow with pump running

2
Flowmeter

Measures water flow from well

Signals

  • • 4-20mA flow rate
  • • Pulse totalizer (optional)

DV8 Displays

Real-time GPM, daily/monthly totals, signal strength

Alarm Examples

Flow too low/high, signal loss, totalizer discrepancy

3
Chlorine Injection

Doses chlorine proportional to flow

Signals

  • • Pump enable DO
  • • Dosing rate command (optional analog)

DV8 Displays

Injection system enabled/disabled, dose rate

Alarm Examples

System fault, low chemical supply

4
Chlorine Analyzer

Measures chlorine residual in treated water

Signals

  • • 4-20mA chlorine residual (ppm)

DV8 Displays

Real-time Cl₂ level, signal strength, trending

Alarm Examples

Residual too low/high, signal loss, analyzer fault

5
Storage Tank

Stores treated water for distribution

Signals

  • • 4-20mA level (ft or %)
  • • High/low level switches (DI)

DV8 Displays

Tank level, volume calculation, fill/drain rate

Alarm Examples

Level too low/high, rapid level change

6
Service Pumps

Maintains distribution pressure

Signals

  • • Motor V/A/kW/Hz (VFD)
  • • HOA/Run/Fault
  • • 4-20mA pressure feedback

DV8 Displays

Pressure setpoint control (PI loop), motor diagnostics

Alarm Examples

Fault, pressure deviation, Leak Detection

7
Hydro Tank/Tower

Pressure maintenance and peak demand buffer

Signals

  • • 4-20mA pressure (psi)
  • • Air Compressor Run Status (if equipped)

DV8 Displays

Line pressure, pressure band maintenance

Alarm Examples

Pressure too low/high, pressure drop
