摘要：本发明公开了一种防磁攻击的流量仪表脉冲传感器，用于管道气体液体浏览量监测与计量的流量仪表，脉冲传感器安装在流量计壳体内，脉冲传感器内安装有磁敏元件A、磁敏元件B或多个磁敏原件；磁敏元件A和磁敏元件B分别连接插入脉冲传感器的信号线；当流量计在复杂电磁环境下使用时，上部的磁敏元件会产生干扰信号，下面磁敏元件也会产生干扰信号，同时下面磁敏元件也会产生有用的流量信号。当在人为强磁攻击下，可使传感器下面磁敏元件接通无信号产生，上面磁敏元件也会接通，经体积修正仪对信号处理判断、异常报警，以实现惩罚性计量或关闭阀门等措施。达到抵制不法分子非法盗用的目的。通过两信号的比较滤波，可提高流量仪表的抗干扰性能。

摘要： A water meter having an electrical counter with an intermittently driving mechanism comprises of a meter case (1). An input pipe (2) and an output pipe (3) are provided on the lower part of the case, and a rotor (5) is provided within it. The output shaft of the rotor is magnetically coupled to the second intermediate gearing via the first intermediate gearing. The second intermediate gearing is connected with the driving mechanism of the electrical counter. Said driving mechanism of the electrical counter is composed of plural actuating elements and actuated elements represented various decades. Furthermore the actuating element and actuated element of the same decade are jointed to a whole unit. Both the actuating element and actuated element of the lowest decade counter device are the first stage gear of the second intermediate gearing. The actuated element of the next lower decade counter device is the final stage gear of the second intermediate gearing. The highest decade counter device only has an actuated element. The plural actuating elements and actuated elements whole or partially are mounted with resistor plates and a reading device can detect the resistance value. Compared with the prior art , the water meter according to present invention can reduce the driving torque, improve the meter accuracy and lower the cost.

摘要： Process measurement may be achieved by systems and techniques generating output signals based on the measured process. In certain implementations, process measurement systems and techniques may include the ability to generate a magnetic field (504) and successively change the orientation of the magnetic field (508). The systems and techniques may also include the ability to sense the presence of at least a first orientation of the magnetic field with a magnetic field sensor including a conductor and at least two Wiegand-effect conductors as the magnetic field orientation is changed (512) and to generate an electrical pulse in the conductor with each Wiegand-effect conductor when the first orientation of the magnetic field is sensed (516).

摘要： A fluid metering device including a housing, an isolated fluid conduit, a metering assembly, an electronics assembly, and a power assembly. An electronic device can be wirelessly connected to the metering device so as to quantify the fluid that is passing through the isolated fluid conduit. Alternatively, this can be performed by the electronics assembly and then transmitted to the electronic device. Portable spraying apparatuses are also disclosed and can include the fluid metering device. In example embodiments, other data can be captured and/or calculated such as sprayer locations, sprayed locations, type of fluid sprayed, images of the intended-to-be-sprayed subject, and/or other information pertinent as desired. In some example embodiments, the electronic device in combination with the fluid metering device can predict the chances of volatilization of the fluid based on specific environmental conditions and the fluid temperature. Finally, the sprayer and sprayed locations can be overlayed onto a map.

摘要： A turbine meter used for measuring the volume of fluid flowing through a conduit includes an elongated housing having an upstream end and a downstream end and a rotor mounted within the housing. A plurality of turbine blades are mounted on the rotor at an angle with respect to the axis of rotation of the rotor which causes each of the rotor blades to have a high pressure surface which faces toward the upstream end of the housing. Each of the rotor blades also has a trailing edge closest to the downstream end of the housing. An extension is included at approximately the trailing edge on the high pressure surface of at least one and preferably a plurality of the rotor blades. The extension has a length and forms an angle with respect to the high pressure surface of the rotor blade on which it is mounted which causes the percentage of error of the accuracy of the meter across a chosen operating range of the meter to be within predetermined limits.
