In the engineering use, the radar level gauge is very extensive nowadays. No matter what the object is in use, it can not avoid the wear and tear, so it is more important for its fault inspection and maintenance.
In the engineering use, the radar level gauge is very extensive nowadays. No matter what the object is in use, it can not avoid the wear and tear, so it is more important for its fault inspection and maintenance. The same is true for the radar level gauge. Here I will use the guided wave radar level gauge as an example to show you how to troubleshoot it.
First, you can check whether the oil level high setting value of the topping radar level gauge is consistent with the liquid level setting value in the PLC program. Because if the parameters set by the two are different, the interface display will be inaccurate.
The second one is to check whether the radar level gauge itself has a problem. By calculation, if the instantaneous current value output by checking the instantaneous liquid level value of the tank is inaccurate, it means that the radar level gauge itself is problematic. Perform other in-depth checks on other internal parameter settings.
To check if there is any problem with the signal transmission line, if the set value of the radar level gauge oil level is the same as the liquid level setting value in the PLC program, you can see that the liquid level instantaneous height value on the radar level gauge VU331 should be the same. The PLC interface displays the same values. Otherwise, there is a problem with the signal transmission line.
By overhauling all aspects of the radar level gauge, the level gauge can be made better and higher quality, so it must be paid attention to in the project.

1, strong, thermostable
Because CPVC compares PP-R, PE-X to be firm. Compared with PP, the PE-X tube, under the similar pressure, CPVC may use a smaller caliber to achieve the same water flow, thereby saving material costs and installation time. Compares with other thermoplastic, CPVC has the remarkable mechanical property under the different temperature, is suitable for the bearing the situation, the application temperature may reach as high as 93°C, the life may amount to 50 years.
2, easy installation
The connection method are very similar with PVC. Most commonly used and simple connection method is resolver cementation. Other connection methods are threaded connection, flange connection and electrode connections.
3, non-corrosive oxygen permeability
CPVC have the anti-oxygen, therefore the oxygen seepage from the radiator will not bring metal corrosion.
4, reducing the infiltration of additives
In order to prevent oxidation, some modified plastics needs to increase the massive antioxidant that may be infiltrated into the water supply system ,causing the ill-smelling smell.
5, without the impact of chlorine in water
A lot of polyolefin materials (including PP, PE) may be decomposed with water, while CPVC is not affected by the impact of residual chlorine in water that there is no cracks and leakage.
6, good flame retardancy
CPVC limiting oxygen index is 60, therefore it will not burn in the air. It has the characteristics : misfires the flame decoction,not to increase the fire set,restrict flame spread,low smoke generation. 7, CPVC has excellent chemical resistance to non-polar strong acid and alkali. Commonly used to substitute the metal to process the corrosive material, such as the poor quality of water, acidic material alkaline matter and other peroxide solutions.
8, the low thermal conductivity
CPVC thermal conductivity is only 1.05. heat is not easy to disseminate from the pipeline, heat loss of pipeline is low.
9, bacteria breeding is not easy
CPVC is not influenced by the impact of residual chlorine in water. So it will not result in cracks and leaks. Inner wall of pipe is smooth, not easy to breed bacteria. The research indicated that the breeding of germs in CPVC pipe is far lower than other materials such as copper, steel and other plastic pipe.
10, low thermal expansion
CPVC thermal-expansion coefficient is lower than other plastics. The tube expansion is very small when tube-pass heat, unlike other types of channels (such as PP-RRP) due to the higher temperature caused by heat expansion coefficient that could cause snake bending,the existence safe hidden danger and eyesores.
11, the test of time
none of a thermoplastic material such as CPVC,avoid the maintenance after 40 year hot water system's test, and displays its excellent performance
