PC series flow accumulation paperless recorderDetailed product description：

Product Introduction
The PC series flow accumulation paperless recorder is a three channel universal input flow accumulation paperless recorder with temperature and pressure compensation function. The instrument can be configured to select input signals such as standard current, standard voltage, frequency, millivolts, thermocouples, and thermal resistors. It can provide sensor power distribution and analog transmission output, as well as two relay contact outputs. Equipped with a standard USB 2.0 interface, it supports data transfer and storage functions.
The PC series flow accumulation paperless recorder fully utilizes the advantages of the LCD screen graphical interface, with simple, intuitive, and convenient configuration, and does not require the secondary calculation of most traditional accumulation meters. It fully considers the engineering issues in flow measurement and combines the successful experience of multiple thermal companies in heat network management to add many new functions for resolving settlement disputes between supply and demand sides in trade.
