Electromagnetic flowmeter installation requirements:
1. Flowmeters that are common in the market now belong to unidirectional flowmeters. The titanium anode plate must be clearly seen when installing electromagnetic flowmeters. Water supply equipment 2, electromagnetic flowmeter converter (head) can not be installed down.
3. Installation location: Permitted to be installed in horizontal or vertical pipelines. Horizontal pipelines must be required to make joints for upward movements at outlets or outlets. The vertical pipe must be installed on the pipe where the liquid moves upwards.
4. Requirements for straight sections before and after: Under normal circumstances, the straight sections before and after are required to be 5D after the first 10D (ie, the first 10 times is 5 times the diameter after the diameter). Special occasions can be reduced or increased.
Correct installation of electromagnetic flowmeter, titanium anode correct product selection:
1. Selection of Electromagnetic Flowmeter Electrodes Problem: Electrodes are selected according to different media, commonly used 316 stainless steel electrodes, corrosive occasions have different titanium electrodes, Hastelloy electrodes, tantalum electrodes, nickel electrodes, platinum electrodes For different electrodes, users can choose according to different corrosiveness.
2, the medium temperature can not be too high, frequency conversion water supply currently used Teflon material lining or polyurethane rubber lining ht, annealing furnace nitrile rubber lining maximum temperature of 200 degrees.
3, should measure the characteristics of electromagnetic flowmeter, the medium must be conductive liquid, conductivity must be greater than 5us/cm.
4. Electromagnetic flowmeters used in high-pressure applications must be watchful and provide the appropriate pressure when ordering. The pressure is divided into the pressure of the pipeline and the actual pressure of the fluid.

The type of drill free grading cement injection device is manily used in straight wells.The strucure is an internal closure structure.When it is opened,it is put into the gravity plug from the wellhead to open the circulation hole.When it is closed,it is put into the closure from the wellhead to drive the closure sleeve down to close the circulation hole.At the same time,it close the circulation hole.The graded cement injection device will be separated from the outer cylinder and will fall freely to the bottom of the well.
