Vari-Gage Pump Controller

Digi-Gage Electronic Pump Controller

Digi-Gage Electronic Controller

Vari-Gage™

Product Status: NOT ACTIVE

The Vari-Gage has been replaced by the Vari-Gage Plus

Variable Speed Controller

The Vari-Gage is a level monitoring system capable of controlling pumps or measuring wet wells and tank levels. This exceptional versatility has been proven in a broad spectrum of applications ranging from critical control of tank levels to monitoring effluent flow in pumping stations.

The Vari-Gage delivers the control efficiency and productivity needed to meet today’s exacting standards. The system uses an internal pressure transducer (15 psi max) or a remote mounted submersible pressure transducer to monitor water and wastewater.

  • Vari-Gage 3300 for up to 3 pumps in a duplex or triplex configuration (variable speed).

Product Features

  • Easy to configure for simplex, duplex or triplex applications
  • Program with only three simple steps!
  • No wires or pneumatic connections to disconnect
  • Three field selectable inputs: 4-20mA; 0-10V, 0-15 psi
  • NEMA 1 housing
  • Easy to read ½” high 7 segment LED
  • Differential level control
  • Level indication (0 – 999 max)
  • 15 discrete LED’s for Mode/Status indication
  • EEPROM (electrically erasable programmable read only memory) lasts for 100 years – no battery back-up required
  • Draw-out chassis construction
  • Pneumatic connector accepts standard 1/4” OD flex tubing
  • Pump up or pump down capability
  • Manual or automatic alternation
  • Performs self-diagnostics upon power up to maintain optimum status
  • MODBUS communications capability
  • Lag pump start delay of ten seconds
  • 100% digital technology — virtually eliminating all sources of drift or error.
  • Level simulation by using UP and DOWN arrow keys
  • Works with Scada Express for implementation of remote station monitoring and control.
