IMP Lite Pulsar Level Measurement

IMP Lite Pulsar Level Measurement can be used wherever you need reliable non-contacting ultrasonic level measurement and digital echo processing means IMP Lite is perfect for slurries or liquids and anywhere you need a display telling you the level, or an analogue output to interface with your site control system or drive a display. The full IMP range is available with the wetted parts in PVDF build alternative for corrosive or aggressive applications.

IMP Lite Pulsar Level Measurement Features

  • 2-wire configuration
  • RJ11 Port
  • Up to 10m range available

Compact and low-profile

When used on battery power for intermittent (wake-up) applications, IMP Lite’s high speed boot up of circa 3 seconds maximises battery life. For example, if an IMP Lite were switched on every 15 minutes for a 3 second reading, average current is a mere 40µA.

Active and passive (sourcing and sinking) analogue outputs assist with system integration, especially when retro-fitting into older installations.
