Flow measurement is not affected by changes in fluid density, viscosity, temperature, pressureand conductivity.
Lining material:
| material |
Main performance |
| Polyurethane rubber |
1. Very good wear resistance coal slurry, mud, ore slurry, etc. 2. Not resistant to acid, alkaline and other corrosive or high temperature media 3. There must be no negative pressure in the pipeline |
| Neoprene |
1. Very good elasticity and wear resistance 2. Capable of measuring domestic sewage, non-corrosive industrial sewage PH value: in the range of 6/7/8, temperature below 80 ºC liquid 3. There must be no negative pressure in the pipeline |
| Perchloroethylene propylene F-46(PTFE) |
1. On the basis of all functions of PTFE, the temperature of non-corrosive liquid can be increased within 140 degrees 2. Not resistant to fuming nitric acid, butyl lithium 3. There must be no negative pressure in the pipeline |
| Silicone fluoride lining |
Temperature resistance: 70 degrees, mainly high temperature. It can be used to measure hot water in heating systems, and is not resistant to corrosion. |
