Electric Output for Mechanical Level

  • The Model 2000 converts tank level (via Dry-seal Gauge Head reel position) to a two-wire 4 – 20 mA output signal.
  • Uses a precision, low drift solid state transmitter for instant-on level readings.
  • Only requires power when a reading is required.

Bolt-on Design

  • No special tools are required, the Model 2000 Goshawk, bolts directly to Model 1000 Redtail or Model 1500 Roadside Dry-Seal gauge heads.
  • 3/4 NPT conduit connections for sealed cable connections.

Absolution Position Encoding

  • The Model 2000 Goshawk uses absolution position encoding to ensure accurate and repeatable level indication.
  • Direct mechanical connection ensures skip-free encoding, and does not require recalibration following power outages.


  • CSA C/US Marked for Class I Division 1 Grade. C & D T6 Also Suitable for Class I Zone 1 IIB T6.
