The meter tube is the piece of pipe in which the orifice plateorifice plateAn orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate ).https://en.wikipedia.org › wiki › Orifice_plateOrifice plate - Wikipedia is installed along with straightening vanes as needed. A typical meter tube consisting of the orifice plate and straightening vanes is illustrated in Figure 12.19. ... The orifice flow rate is the mass flow rate or volume flow rate of gas per unit of time.
What is a meter run?
A meter run is an assembly consisting of an orifice plateorifice plateAn orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate ).https://en.wikipedia.org › wiki › Orifice_plateOrifice plate - Wikipedia with flanges and calibrated upstream and downstream pipes. Since the meter run is manufactured as one unit, it is possible to optimally match all components with each other. Thus any faults that might lead to measuring inaccuracies can be avoided.
