The working principle and structure of the flow totalizer

1. Working principle The flow totalizer is used for collecting, displaying, controlling, remote transmission, communication, printing and other processing of various signals such as temperature, pressure and flow on site, forming a digital acquisition system and control system, suitable for liquid, general Total flow measurement and control of gas, superheated steam, saturated steam, etc. 2. Principle and structure A paperless recorder with three-channel input and three-way flow accumulation function. The instrument can input standard current, standard voltage, thermocouple, thermal resistance, frequency and other signals, and can provide sensor power distribution output, analog transmission output, and relay contact output. Directly connect to the micro-printer to print real-time, historical data and curves at the time specified by the user; connect with a portable computer and a PDA through the RS232 communication interface to directly read the historical data of the instrument, and the user can use the data management software to carry out the data. Analysis, archiving, printing processing. Through the RS485 communication interface, it can form a real-time monitoring system with professional configuration software such as Kingview and MCGS. The instrument has powerful display functions, high-precision bar graph display, real-time trend curve display, historical curve recall, over-limit alarm, alarm status display, and automatic playback of intelligent historical trends. 3. Principle-related features 1. The flow totalizer is used in conjunction with various flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters, and can measure the flow parameters of various liquids, steam, natural gas, and general gases. Carry out measurement display, accumulation calculation, alarm control, transmission output, data acquisition and communication. Features ● Full range of automatic temperature and pressure compensation calculation, the compensation method can be set arbitrarily ● Linear accumulation, square root calculation can be arbitrarily set ● Instantaneous flow, cumulative flow, temperature, pressure display of various parameters ● Small signal cut-off function, cut off The range is 0-5% optional ● The accumulated flow value can be reset to zero through the panel keys, and the reset operation can be locked
