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.
