  • Page 16: Electrical Connections

    P2.x AMEX 4.4.1.2 Monitoring measures when conveying flammable and/or toxic gasses Conveying flammable and/or toxic gasses further requires continuous monitoring of the sample gas pump during operation. This can be done as follows (1) or (2). Flow rate monitor before the pump’s gas inlet and after the gas outlet. A sudden reduction of the suction volume / flow volume ahead of the pump and consistent or suddenly increased flow volume after the pump indicates a defective bellow (the pump can convey ambient air suctioned in due to the tear).
