Chilled water energy metering system
Chilled water energy metering system
(OP)
Dear All
I want to sell chilled water to our customer, we will use energy metering system to measure energy absorbed by our customer. Can anybody recommend the type and accuracy of this metering system? Our chilled water flow rate is 4,500 m3/hr? This is to transfer cooling load of 12,500 RT(Refrigeration ton). The chilled water supply 5 deg C and return is 14 deg C.
Regards
ARP

RE: Chilled water energy metering system
However Endress+Hauser and Krone Marshall have those type of meters with inbuilt temperature transmitters and processors for calculation.
A Vortex Flow Meter with 0.5% maximum error (for liquids) is relatively cheaper and better option in your case.You should take care of sizing by avoiding redundancy (general, I mean)
