Permalevel® SINGLE POINT

Non-Invasive Constant Level Monitoring Technology

The Permalevel® Single Point is a fixed-level monitoring device designed for use in a variety of industrial, safety and manufacturing applications. 

The sensor, placed on the outside of the tank, can trigger an alert if the liquid level rises or falls below a fixed point, sending a 4-20mA output to interact with other equipment.

Overview

Non-invasive level monitoring system

The Permalevel® Single Point is designed to offer maximum flexibility across a wide range of fixed-point level monitoring applications. The main principle of the system involves fixing an ultrasonic sensor to a critical position on the side of the container being tested. This critical position can be found and verified using a Portalevel® unit and the Portasteele® Calculator. The unit will then non-invasively monitor whether or not liquid is present inside the cylinder at this point. As soon as the liquid level rises above or falls below this point, this will trigger an alert from the Permalevel® Single Point. This alert can interface with any alarm or management system operating in the facility. There are a wide variety of applications for this system, including pressurised cylinders, storage tanks and pipes.

Frequently asked questions

Yes, it can, providing that the temperature of the CO2 container is kept reasonably stable. The density of CO2 can vary quite considerably with temperature, so if your cylinder is kept outdoors where temperature may vary greatly, the Permalevel® Single Point may not be suitable. In fact, at temperatures above 31°C, it is not possible to use any liquid level indicator for CO2 monitoring, as it will reach its critical temperature and there will be no liquid level.
