Abstract:
A condensate drain apparatus including a valve for controlling discharge of condensate from the condensate drain apparatus; a collection chamber configured to receive a multiphase fluid flow upstream of the valve including gaseous and condensate phases, the collection chamber defining a collection volume for collecting the condensate to be discharged through the valve; sensor equipment for monitoring a parameter relating to a thermodynamic property of the fluid upstream of the valve; a controller configured to monitor the condensate collected in the collection chamber based on the monitored parameter, and to control the opening and closing of the valve to regulate the condensate collected in the collection chamber upstream of the valve; wherein the controller is further configured to determine the quantity of condensate discharged from the collection volume using a flow rate calculation for a choked flow of vaporizing liquid.
