For example, pressure gauge, logic unit (such as alarm signal unit) and valve constitute a safety related system. 2.4 Safety Functions Specific functions performed by safety related systems, whose objective is to achieve or maintain the safety status of the plant in consideration of defined hazardous events. Example: Limit pressure monitoring 3 Other applicable documents and documents The flowmeter must provide the following documents.
