Then if the high and low pressure conduits link back, the transmitter is not working properly, or need to be removed and reconnected. The following is a description of the differential pressure transmitter's reverse connection.
For transmitters that measure static pressure levels, the pressure-transmitting tube is connected backwards, which can reverse the output. When the liquid level is the lowest, the output is 100%. When the liquid level is the highest, the output is 0%. The differential pressure meter that did not migrate in the early years is used as such.
However, when the flow rate is measured, the pressure guiding pipe is reversed. Generally, it cannot work normally, and it needs to be removed and re-linked.
Forward refers to the transmitter differential pressure signal increases, the output also increases, reverse refers to the differential pressure signal increases, the output decreases, any forward and reverse can be converted transmitter, if the pressure pipe reversed , as long as it is changed to reverse output state, and then plus a certain positive and negative zero migration, you can make the transmitter in the normal output direction.

Reaming of aluminum reaming parts generally adopts carbide, coated carbide, and PCD reamers. Generally, the built-up edge is the biggest problem in processing aluminum parts. The generation of built-up edges will lead to adverse effects such as enlarged pore size and excessive roughness.
On the whole, the PCD reamer can use a higher linear speed, effectively avoiding the generation of a built-up edge.
But if the cemented carbide tool is designed properly, it can also be processed with good precision. Especially for the use of coated tools, the correct selection of the corresponding coating can not only meet the accuracy requirements, but also have the advantages of stable wear resistance and chemical properties, heat resistance and oxidation resistance, small friction factors, and low thermal conductivity. However, coated blades are not as sharp as uncoated knives because the cutting edge is passivated when the knives are coated. The sharp cutting edge can also effectively prevent the formation of a built-up edge, so the processing of aluminum alloy tools is generally not coated.
