Pulse Transmitters | Veeder-Root

Pulse Transmitters | Veeder-Root

Veeder-Root Pulse Transmitters (Pulsers) models 1871, 7697 and 7671 were designed to automate the Mechanical Meter Register 7887 and can be used in other applications that require precise emission of pulse signals to a remote display or data system.

The Pulse Transmitter model 7733 was designed exclusively to automate the Mechanical Meter Register VR-101 used in mechanical fuel pumps for commercial use.

Precision, durability and reliability are the hallmarks of Veeder-Root Pulse Transmitters (Pulsers).

MODELS 1871 AND 7697

  • Fast, accurate pulsing for counters, printers and stepping motors with remote indicating and data monitoring system.
  • Minimum contact bounce.
  • Mount in any position.
  • Approved for use in hazardous locations Class I, Group C and D.

MODEL 7671

  • Solid state switching mechanism that provides fast and accurate signaling for remote indication, totalizing and data monitoring systems.
  • Directional operation
  • Mount in any position.
  • Approved for use in hazardous locations Class I, Group C and D

MODEL 7733

  • Easy installation. Replaces the liter totalizer Mechanical Meter Register VR-101.
  • Simplified wiring.
  • Pulse adjustments not required.
  • Backstop bearing and glass display that prevent unauthorized adjustment of registered totals and over counting due to sudden closure of the fueling nozzle.
