Before purchasing the KATflow 200, it had to interrupt the process and introduce an orifice meter or V-notch weir and mechanical flowmeter to measure flow.
The basis of this recommendation is that the elements of an AHU possess stable aerodynamic characteristics that can be used as an effective orifice meter. Heat exchangers and heating coils, as well as cooling coils for AHUs operating in cooling mode without air drying, can be used as measuring elements.
(Emphasis has been added to highlight the need to ensure that the orifice meter run has been manufactured to the specifications of the standard.)
The pipes, attached to an orifice meter to check the flow of secondary coolant, are similar to the one that ruptured and caused the fatal accident.
Years of testing show the orifice meter to have a very reproducible and predictable wet gas flow performance.
The checking was mainly conducted around the downstream part of the orifice meter for secondary cooling water.
Reducing the bore diameter will increase the pressure drop of the orifice meter and report incorrect mass flow.
An orifice meter consists of a straight piece of pipe called the meter tube plus a round metal plate with a hole through its center known as the orifice plate.
A proper orifice meter installation is one key to accurate flow measurement.
