33、e general requirements on leak detection systems according to Clause 5 of EN 13160-1:2016 shall be met. Liquid or vapour sensors shall be installed in such a way that they can detect specific liquids or their vapours present in or entering the leakage containment, interstitial space or monitoring we

34、lls. The sensor shall react within a time specified by the manufacturer. The leakage containment can take the form of a sump or riser designed to contain spills from leaks originating from pipework or pumps/dispensers; bund, designed to contain leakage from an above ground storage tank or from any o

35、ther above ground facility containing liquids; other facilities in which sensors can be installed to detect the presence of liquids or vapours. An alarm device according to EN 13160-3:2016, 4.1.3.5, shall be provided. In the event of a sensor disconnection of the power supply an alarm condition shal

36、l result. In case of a short circuit between two conductors in the connection between sensor and evaluation device an alarm shall be triggered. 4.1.2 Presence of liquids Liquid sensors shall detect specific liquids they may come into contact with (e.g. stored/conveyed product, water), according to t

37、he following requirements: Category 1: Non-discriminating sensor. The sensor shall detect the presence of any liquid (stored/conveyed product and water). Category 2: Discriminating sensor.
