• Shut-off valve: Shut-off valve: pneumatic, normally closed shut-off valve, with additional metering screw
• Primary element (calibrate orifice)Primary element (calibrate orifice): used to measure the flow rate by means of a pressure transducer (shall induce a pressure loss at nominal flow rate of less than 100 mbar)
• Small piping for instrumentation (before and after the orifice), equipped with Schrader valves on the control rack
• Shut-off valveShut-off valve: pneumatic, normally open
• Non-return valveNon-return valve: by-pass for the shut off valve in case of overpressure on the detector circuit
