Circuit board set parameters and wiring method of Roots flow meter & Gear flow meter
Parameters setting
1.1.1 Accumulated flow (total volume) to keep three decimal places, integer bit eight spills automatic reset;
1.1.2 Instantaneous flow is volume flow (m3 / h), most can be kept 3 decimal places, shows a maximum of 9999999;
1.1.3 Temperature and value range is -50 ~ + 300 ℃, if beyond this range, the presenting bank tip OV (parameters beyond), at the same time interior call compensate temperature setting, and prompt the ST (with temperature compensation);
1.1.4 Pressure display value reserve two decimal places, range is 0 ~ 99.999 MPa, if beyond this range, the presenting bank tip OV (parameters beyond), at the same time interior call set pressure value to compensate, and prompt the SP (with pressure compensation).
1.1.5 Instrument normal work, tip OK, if mistakes, the tip ERR, and have corresponding error
