Plan 21/23 Heat Exchangers
(OP)
Trying to get a feel as to how often you guys utilize an in-line flow meter on the cooling water supply upstream of the heat exchanger on a plan 21/23? I know the seal vendors typically require a certain cooling water flow to achieve "X" amount of temperature cooling and none of our exchangers have flow meters on the cooling water supply. What are your typical plan 21/23 installations like?

In Plan 21 you may use Orifice to control the flow. normally 3 to 5 lpm flow is recommended by seal manufacturers. An orifice can be designed for desired deltaP and flow.
In Plan 23 flow need not be measured. Only soaked heat and heat generated by seal is to be removed. If you tell me the seal size , RPM and pressure, I may tell you the size of the heat exchanger to be used (i.e. how many kW heat is to be removed).

I am more concerned with how to monitor and control cooling water supply to the exchanger. DO most of you just simply use a site gauge or an actual flow meter to ensure you have adequate cooling water flow to the exchanger?
