Home> flow meter >> accumulating and controlling instrument >> HR-LCD-XL LCD Flow (heat) Totalizer
  • Introduction
  • Specifications
It is a intelligent second instrument with multi-function. It is used to measure and totalizer the flow for all kinds of liquid and gas. It uses new microprocessor with flash memory in the hardware and extends the data store capacity. It can connect with three measured signal to satisfy the calculate requirement for pressure compensation and temperature compensation. The printing part can be connecting with printer with RS-232C series interface directly to finish time print, instant print or alarm print.
