Intelligent temperature and pressure compensation type flow integrator

1Intelligent temperature and pressure compensation type flow integratorOverview

YK-98The series intelligent flow integrator adopts advanced microcomputer chips and technology, and is used in conjunction with various flow sensors or transmitters, temperature sensors or transmitters, and pressure transmitters. It can measure and display flow parameters of various liquids, steam, natural gas, general gases, etc., accumulate calculation, alarm control, transmission output, data acquisition and communication.

IIIntelligent temperature and pressure compensation type flow integratorFeatures

uFull range automatic temperature and pressure compensation calculation, compensation method can be set arbitrarily

uLinear integration and square root integration can be set arbitrarily

uDisplay of multiple parameters including instantaneous flow rate, cumulative flow rate, temperature, and pressure

uSmall signal resection function, resection range 0-5% optional

uThe accumulated traffic value can be reset to zero through the panel buttons, and the reset operation can be locked

uPower off protection function, accumulated flow value, power off retention time greater than10Year, all set values remain unchanged after power failure

uAdvanced modular structure, combined with powerful instrument chips, makes it very convenient to combine functions and upgrade systems

uSupport multi machine communication, with a communication baud rate of 300-9600bps. The internal parameters of the instrument can be freely set

uCan be directly connected to a serial micro printer
