Position realizes that flow velocity increases, and enhances the output signal of measuring electrode, reaches the output signal that can be measured, to increase measurement model
It encloses, range extension ratio, meanwhile, adapter flange reducer taper, pipeline crushing can be controlled reasonable through reasonable settings
One within the scope of.Undergauge pipeline entirety interface is circle, can be to avoid generating excessive crushing to medium.
Further setting: adapter flange is provided with a bit of straight pipe, In far from the other end inner hole of reducer
Pressure port can be set on the straight pipe, it can be with processing sets up in the environment of needing pressure.It herein can be to need to carry out
The place of pressure detecting provides an interface, and straight pipe is conducive to the sealed set at pressure interface, if carried out in undergauge section
Pressure is then unfavorable for the leakproofness setting of pressure taking structure.
Further setting: grounding electrode quantity is 1, is arranged on measurement pipe central bottom outer wall, and through measurement
Pipe and lining；Grounding electrode quantity is also possible to 2, is vertically arranged on the symmetrical outer wall in measurement pipe middle, and through survey
Buret and lining.
Zero potentail reference can be set for measuring signal by grounding electrode setting, save setting for other earthing modes
It sets, in addition the setting of 2 grounding electrodes, can alarm to provide for blank pipe more accurately judges signal.
Further setting: gauge outfit component can be replaced to be fixed in terminal pad with Split type connecting box, the gauge outfit group
It is electrically connected between part and Split type connecting box, the place for split installation gauge outfit component.
The setting is not suitable for installation at the scene in bad environments, gauge outfit component, or needs for table group head to be arranged and grasp
Make to use in the case where the place that personnel can check, avoid being influenced by adverse circumstances, operator's use can also be conducive to.
In conclusion the utility model has the following beneficial effects:
Electromagnetism water meter involved in the utility model can measure flow velocity more lower than through-type electromagnetism water meter, to increase
The range ability that can be measured, structure is simple, and processing and assembling are all very convenient, while using multiple electrode structure, and it is suitable to guarantee
While zero potential, the occurrence of capable of effectively preventing blank pipe.
