Industrial Grade Digital Meters - Aluminum FLOMEC®

Aluminum
Aluminum

(Was Model 31904A)

Meter Type
Industrial Grade Digital Turbine Flow Meter, battery powered that displays rate of flow and totals.

How It Works
Magnetic pulses are picked up by a coil. The computer converts the pulses into a flow rate and totals.

Standard Features

  • Rate of Flow, 2 Totals (1 Resettable Batch, 1 Cumulative)
  • User Configurable to GPM, LPM or any Unit of Measure
  • Factory Calibrated for 1.0 Specific Gravity
  • Field Calibratable for fluids greater than 1.0 Specific Gravity
  • Digital Display with 6 Digits Starting at 0.01 (floating decimal)
  • Totals Maximum of 99,999,999
  • Powered by (2) 1.5V AAA Alkaline Batteries (2-year life)
  • Factory Calibration Certificate supplied with each meter
  • Suitable for Fuel, Diesel, Petroleum Based Products or other suitable applications
  • 1 Year Limited Warranty

Application Notes

  • Saturated Steam Service: Not acceptable
  • Potable Water: Not acceptable (See Series GPI- QSE)
  • Vacuum Service: Not acceptable
  • Gaseous Service: Not acceptable
  • General Non-Suitable Services: Not recommended for water applications. Not suitable for medias with varying viscosities.
  • Installation: Limit display’s exposure to sun.
  • Corrosion: Before ordering, verify all materials of our flow meters are compatible with the service media(s), intermittently used cleaners, the environment, and cleaning processes in conjunction with the temperatures and pressures of the application(s) and future applications. John C. Ernst Co. does not make chemical compatibility recommendations. Compatibility is the responsibility of the user and/or specifying party.
