摘　　要：静压法储罐计量系统(HTG)的原理就是用压力或差压变送器测量油品介质作用在罐底部静压的方法来测量储罐内介质质量。系统压力或差压变送器信号输出采用HART现场总线协议,数字信号传输通过RS485进行MODBUS通讯。The work principle of HTG is that medium quality in oil tank is measured with the method that static pressure of bottom of oil tank is measured with pressure or differential pressure transmitter. HART field-bus protocol is used in output of system pressure or differential pressure transmitter, digital signals is transmitted with MODBUS via RS485.

关 键 词：静压法储罐计量系统 差压变送器 介质 HART现场总线协议
