Hi All

I need to check if I have the correct water flow rate through a chiller.
I have a 'binder' point on the flow pipework & return pipework from the chiller so I can put a pressure gauge on each and get a pressure drop through the chiller.
I know what the pressure drop should be through the chiller at the correct water flow rate.
So is this the correct or best way of determining the flow rate through the chiller or have I got it wrong. Any help advice would be appreciated

Thanks
