1. Brief Introduction
LU**0K may suit for already square root or not square root differential-pressure signal. It specially connected with orifice flowmeter

suit for flow measuring of each kind of liquid, gas and vapor, and will carry on the compensation calculation according to the measured medium’s temperature and pressure. It has many methods, may connected with frequency pulse sensor such as vortex or other flow transmitter of ***0mA output or ***0mA output.
 adopts the looking for form compensation method, may carry on high precision compensation calculating for excessively hot vapor, saturated steam and has many display method, may display the accumulated flow, instant flow, pressure, temperature frequency, density and time, the display interval can be set willfully.
 may set ten different flow constant according to the different frequency, and will automatically calibrate the flow constant with interpolation algorithm.
