5. 安装及接线方法

5. Installation and connection method

探头的安装及接线方式：

The probe of the installation and connection mode:

1． 该探头在安装时需根据管道材质和规格选用专用的安装底座，其他方式的安装可能会导致探头测量精度受到影响；

1. The probe when installation should be selected according to piping material and specifications for the installation of the base, the installation of other ways may lead to probe measurement accuracy affected;

2． 探头安装件选用三通式垂直与被测量管道的安装方式，安装件与三通出厂前已经粘接完毕，可以直接使用；

2. The probe installation piece choose three general formula is measured with vertical pipe installation, the installation and tee before delivery is adhesive, can be used directly;

3． 如果被测量管道是金属管道，则安装件需要用法兰进行过渡转换，转换时需注意直线段要求。

3. If you are measuring pipe is a metal pipe, install a need to use the flange to convert the transition, transformation needs to pay attention to the line segment.

4． 选用的安装件必须与被测管道的公称直径相一致；

4. Select installation pieces must be consistent with the nominal diameter of the pipeline under test;

5． 在安装件与管道粘接时注意探头的垂直角度，探头尽可能保持垂直状态；

5. When installing a piece and pipeline adhesive pay attention to the vertical Angle probe, probe as far as possible to keep the vertical state;

6． 红色线为12V/DC直流电源正极,接JMA多阀控制器14#接线口；

6. The red line is the 12 v/DC DC power anode, valve controller by JMA was 14 # wiring mouth;

7. Shielding wire is 12 v/DC DC power cathode, valve controller by JMA was 15 # connection port;

8． 白色线为信号输出端（脉冲信号输出）, 接JMA多阀控制器16#接线口；

8. The white line (the pulse signal output) for signal output end, more than by JMA valve controller 16 # connection port;

6.  维修及保养

6. Repair and maintenance

探头的维修及保养：

Probe the repair and maintenance:

1． 探头在安装前需确认叶轮自由转动自如，没有明显的卡位现象；

1. The probe free in before installation, check to ensure that the impeller rotating freely, no obvious screens phenomenon;

2． 当流量计出现停止计量时，且确定被测液体仍然在流动时，可以在线检查流量探头的工作方式。

2. When there is stop measuring meter, determine the liquid is still being tested in the flow, can check the flow probe works online.

将探头上端背母拧下，观察探头背部发光二极管的工作状况，如果二极管出现常亮或常灭的现象，说明管道内叶轮已停止转动，此时需要停止管道工作，将管道内压力全部泄掉，然后拆下探头，检查叶轮周围是否有异物影响叶轮转动。

Will probe the upper back unscrewing, observe the probe back the working condition of light-emitting diodes (leds), if the diode normally on or destroy phenomenon, often shows that the pipe has stopped rotating impeller, the need to stop working pipe, the pipe inner pressure drain off all, and then remove the probe, to check whether there is foreign body impact around the impeller impeller rotation.

清洗后如果手动转动工作正常，且背部二极管正常工作，确认安装正确后可以继续使用。

If manual rotation normal work, after cleaning and back diodes to work properly, can continue to use after confirm correct installation.

3． 如果探头出现叶轮破裂、探头顶端支架破损、轴承弯曲、经修复叶轮仍然无法自由转动、与液体接触部分出现被腐蚀现象、安装部位丝扣受损严重时，需更换新的探头。

3. If the probe in the impeller fracture, probe the top bracket damaged, bearing bending, the repair still not freely rotating impeller, contact with the liquid part of the corrosion phenomena and install thread is severely damaged, need to change a new probe.

4． 如果探头背部二极管闪烁工作正常，二次表仍然不能正常工作，请检查探头导线是否有破损，并且可以用万用表在屏蔽和黑色线之间测量电压是否正常。

4. If the probe back diodes flash works well, the second table still doesn't work, please check the probe wire to see if there is any breakage, and can be measured with a multimeter between block and black line voltage is normal.

二极管亮则无电压输出，二极管灭则有电压输出。

Diode light, no voltage output, diode has the voltage output.

5． 由于液体内污渍可能会引起叶轮转动不顺畅，可能会影响液体测量的精度。

5. Due to the stains in liquid may cause impeller rotation is not smooth, may affect the liquid measuring precision.

因此需要定期对探头的叶轮部位进行检查和清洗。

So we need regular inspection on impeller part of the probe and cleaning.

探头K值参考表：

Probe K value reference table:

K值的含义表示每单位体积流过探头时，探头所产生的脉冲个数。

The meaning of K value said per unit volume through the probe, the probe pulse generated by the number.

例如：在DN100的PVC管道中，如果设定K值为1，则表示每流过探头1公升水，探头会产生1个脉冲信号。

In DN100 PVC pipe, for example, if the set value of 1 K, says each through the probe 1 liter of water, probe produces a pulse signal.

因被测量的管道内径不同的变化，用户可以用调整K值的方法进行调节。

By measuring the change of different pipe diameter, the user can use the method of adjusting K value.

流量传感器在出厂时将随机给出PVC管道DN40、DN50、DN65、DN80、DN100条件下经过实验室标定所得到的K值参考值。

Flow sensor in the factory will be given randomly PVC pipe DN40, (, DN65, DN80, under the condition of DN100 calibration in the laboratory to get the K value of reference.
