Akış Hesaplama Ölçer (lu-50)

1. Brief Introduction

LU-50 is suitable for the flow measuring of all kinds of liquid, gas and vapor, and will carry on compensation calculation according to the temperature and pressure of medium measured.

LU-50 has many input types, may connect with frequency pulse sensor, such as vortex flowmeter, and other flow transmitter with 0-10mA /4-20mA output.

LU-50 adopts look-up table compensation method, may carry on high precision compensation for superheated steam and saturated steam.

LU-50 has many display methods, may display the cumulative flow, instantaneous flow, pressure, temperature frequency, density and time, and the display refresh cycle can be set freely.

LU-50 may have ten different flow constants according to different input frequencies, and will automatically calibrate the flow constants by interpolation algorithm.
