1、Summary
YK-98-88LCD Series Inligent Flow Totalizer PID control, adopts advanced microcomputer chip and technology, and with the use of various flow sensor or transmitter, temperature sensor or transmitter and pressure transmitter, on a variety of liquid, steam, gas, general gas flow parameters were measured by cumulative calculation, display, alarm and control, analog PID control valve, data acquisition and communication.
2、Function characteristics The full range of automatic temperature pressure compensation calculation. Calculation function the user can set Flux signal linearity or root can set. LCD visual display of multiple data. Small signal elimination, rage 0.0~5.0% With PID control flow function, control a constant flow。The output signal of the control valve opening 3、Technical specifications Flux input ：DC0～5V、1～5V、DC4～20mA、0～20mA、0～10mA Pulse signal 0-10KHZ square sine wave eq. voltage amplitude >4V Pressure input ：DC0～5V、1～5V、DC4～20mA、0～20mA、0～10mA Temperature input: DC0～5V、1～5V、DC4～20mA、0～20mA、0～10mA Thermocouple K, S, B, T, E Resistance temperature Detector Pt100, Cu50, Cu100 Measurement accuracy : 0.2％FS±1 digit Resolution: 1, 0.1 Display : LCD pixel 128*64 sampling period： 0.5S Control output: relay ,SSR 4～20mA, 0～10mA, 1～5V, 0～5V.
