PLI Gauge

The PLI Portable Liquid Level gauge is designed to offer a simple, accurate, rapid and reliable method of determining the liquid level of CO2, Halon, FM200, Propane and any liquefied gas under pressure, without having to weigh the cylinders. It will also indicate the level of oil or water in a container.

The PLI liquid level meter generates an ultrasonic sound wave that travels through the steel of the cylinder and into the liquefied gas. The pulse responds differently to the presence or absence of liquid indicating the level of the liquid.

The complete PLI kit includes:

  • PLI Gauge
  • Sensor with1.5m Cable
  • Protective Leather case with neck strap
  • Couplant
  • Three-section telescopic extension arm for reaching to the back of banks of cylinders
