To help you be compliant with IMO SOLAS FSS Code & ISO14520 for fixed gaseous fire extinguishing systems and NFPA 12 codes, look no further. (Scroll down for details.) Our unique place in the monitoring of liquefied gaseous extinguishing systems is that we cross-verify liquid level contents with agent mass calculations in a unique Portalevel™ MAX –Portasteele™ Calculator combination which has never been done before. We are launching a new remote constant monitoring system too – Permalevel™.
