 The main technical parameters 
 Should grasp the two principles in the selection process; namely: to ensure production safety, and second, to ensure accuracy. So we must implement the three selection parameters, ie, in the recent and long-term maximum, minimum, and commonly used in traffic (mainly for the selected instrument nominal diameter), the design pressure of the measured media (mainly for the nominal pressure of the selected instrument level), the actual working pressure (mainly for the selected instrument pressure sensor pressure rating). 
 When known to the measured traffic volume flow rate for the working conditions, the adapter can be directly selected by the flow range in Table nominal diameter. 
 (b) known to the measured flow volume flow under standard conditions, the first standard volumetric flow QN conversion to volumetric flow rate Qv working conditions (according to the flow range of technical parameters in Equation 2), and then select the appropriate the nominal diameter. 
 (c) Do not allow the actual minimum flow Qmin below the selected nominal minimum diameter flowmeter flow. 
 (d) have special requirements on the flow range, nominal pressure protocol order.
