    • In a fluidic flowmeter for measuring the flowrate higher than the preset flowrate by use of a fluidic element and for measuring the flowrate lower than the present flowrate by use of a flow sensor inserted into the nozzle portion, the present invention relates to the fluidic flowmeter that has an abnormality judging circuit for judging an abnormality and issuing a warning signal and also zero point and gain correcting circuits when operating the flowrate on the basis for the signal being output from the flow sensor in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the event that the flowrate signal lower than the preset flowrate is to be input only from the fluidic element side.
    • 在流体流量计中,通过使用流体元件测量高于预设流量的流量,并且通过使用插入到喷嘴部分中的流量传感器来测量低于当前流量的流量,本发明涉及流体流量计, 在流量信号高于预设流量的情况下,具有用于判断异常并发出警告信号的异常判断电路,以及在从流量传感器输出的信号的基础上操作流量时的零点和增益校正电路 仅从流量传感器侧输入,并且在仅从流量传感器侧输入高于预设流量的流量信号的情况下,以及在要输入低于预设流量的流量信号的情况下 仅从流体元件侧。

    • A number of remote terminals are connected to various utility meters to store the readings therein. A central terminal sequentially transmits signals to the remote terminals to actuate the same to transmit the meter readings to the central terminal. Each remote terminal comprises storage units to store the readings of the meters respectively. Each storage unit is designed to store the number of digits required for the meter reading, and also a code digit which indicates the type of meter (gas, electric, etc.) or instructions (skip to next meter, remote terminal address, user number, etc.). The code digit is transmitted as if it were a part of the meter reading. A connector card is insertable into a receptacle to detachably set the codes into the storage units of the remote terminals.
    • 多个远程终端连接到各种公用事业计量表以存储其中的读数。 中央终端顺序向远程终端发送信号以启动它们以将仪表读数发送到中央终端。 每个远程终端包括分别存储仪表的读数的存储单元。 每个存储单元设计用于存储仪表读数所需的位数,以及表示仪表类型(气体,电气等)或指令(跳到下一个仪表,远程终端地址,用户号码 等)。 代码数字被传输,就像它是仪表读数的一部分一样。 连接器卡可插入插座中以将代码可拆卸地设置到远程终端的存储单元中。
