Controllers & Temperature Controllers

I. Overview

The LU-50K flow totalizer is suitable for flow measurement of various liquids, gases and steam, and can perform compensation calculation based on the measured pressure. It offers multiple input modes and is specially designed for orifice plate flowmeters, accepting square-root-extracted or non-square-root-extracted differential pressure transmitter signals of 0-10 mA and 4-20 mA. The LU-50K flow totalizer adopts a table-lookup compensation method, enabling high-accuracy compensation calculation for superheated steam and saturated steam. It provides multiple display modes and can display cumulative flow, instantaneous flow, pressure, temperature, frequency, density and time, with the display refresh cycle freely settable. The LU-50K flow totalizer can be adapted to both square-root-extracted and non-square-root-extracted differential pressure signals simply by setting its internal parameters. The LU-50K flow totalizer adopts WATCHDOG circuit, software trap, redundancy, digital filtering and other technologies, giving the whole instrument strong anti-interference capability.
