Pulsar Velocity Interface Wall Mounted

Pulsar Velocity Interface Wall Mounted

Pulsar Velocity Interface Wall Mounted is a digital to analogue converter that works with the latest Speedy velocity sensor in two important ways. It frees up the RS485 output from a FlowCERT controller in applications where digital communications are required, and allows users of Pulsar’s older equipment to upgrade to the latest Speedy sensor. It also provides the option of alarms based on flow velocity.

The Velocity Interface controller is very easy to use and may be calibrated quickly and simply via the on-board keypad and display, or alternatively by using the optional handheld calibrator, which connects to the unit via the RS232 interface and provides an on-board LCD display.

Pulsar Velocity Interface Wall Mounted Features

  • Allows Modbus or Profibus comms when using Speedy sensor
  • Gives backwards compatibility to previous Speedy units
