Variable Speed Controller
The Vari-Gage is a level controller for pump stations, wet wells and tanks, proven across applications from critical tank level control to effluent flow monitoring. It reads an internal pressure transducer (15 psi maximum) or a remote submersible transducer.
- 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
- Three-step programming
- 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 to 999 max)
- 15 discrete LEDs for Mode/Status indication
- EEPROM (electrically erasable programmable read only memory) lasts 100 years; no battery backup 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
- Fully digital measurement that virtually eliminates drift and error
- Level simulation by using UP and DOWN arrow keys
- Works with SCADA Express for implementation of remote station monitoring and control.
