Fixed weight monitoring system for CO2 & Inert Gas cylinders

24/7 Fast-acting Contents Loss Monitoring for Inert Gas, CO2 and Clean Agent Fixed Fire Suppression Systems

The most accurate and fast acting constants loss monitoring system of its kind. Capable of detecting a loss of agent mass to within 1% and provides accurate percentage pressure loss of Inert gas systems associated with agent contents leakage.

Fixed weight monitoring for fire suppression systems

Overview

The Permalevel™ Featherweight is our innovative answer to the need for CO2 and Clean Agent cylinder contents constant monitoring because we recognise the need for one master control to display the constant agent weigh fluctuation in high pressure gaseous system installations covering up to twelve cylinders. Merging fundamental mathematics to enable true constant monitoring along with cutting edge engineering that could be easily retrofitted, bringing you our latest addition to the complex continuous monitoring technology.

Monitoring the mass of your cylinder contents is a fundamental way of measuring agent loss, against the risk of accidental discharge or slow seepage of agent and is the only method that is not affected by pressure or temperature. This enables cylinders to be constantly monitored 24/7 with the Permalevel™ Featherweight to ensure they are at designed capacity, but we also provide real-time information on the exact amount of agent in the cylinders to less than 1% accuracy above 10kg agent weight or 100g below.

During a leak event, the system will show you the exact amount of agent loss, including percentage loss in each cylinder, and if monitoring Inergen™, it will show pressure loss, which is intrinsically linked to mass, all displayed on a full-colour 4.3” display. “Technology that is designed for total flood fire suppression systems in high-pressure seamless cylinders.”

      • Monitors up to 12 cylinders (48 by connecting 4-main units together using on power source).
      • Accurate to 10g or less than 1% above 10kg total cylinder weight.
      • Converts mass loss in Inert gas systems into equivalent pressure loss.

 

What's in the box

Main Electronic Unit: Sophisticated electronic control unit capable of monitoring up to 12-cylinders and connecting four additional units together sharing one-power source. Communication ready for easy fire panel integration.

Hanging Mechanism: Entire mechanical hanging kit needed to support and hang the cylinders under the weight sensors. Unique locking plates allow the user to quickly and easily remove the sensor without disconnecting the cylinders, saving down-time.

Load Cell Sensor: Highly accurate 200kg capacity strain gauge sensor used to send weight measurement data to the main control unit for processing.
