How to determine the quality of a orifice plate flow meter
Thread Content
Due to the special structure of orifice plate flow meters, it is sometimes difficult to determine which fixture is most suitable for a particular sample. Generally, the decision is made based on the following three factors: 1. Whether the orifice plate flow meter is easy to use and safe to operate. 2. The clamping must be reliable; there should be no slippage. 3. During the testing process, the sample breaks at an appropriate point. The data has low dispersion. (i.e., outside the test specimen, inside the jaws, in the parallel section, or outside the gauge length)
In fact, it mainly depends on the differential pressure value; whether there is a blockage in the pipe or in the orifice plate is determined based on the normal flow rate of the process
The quality of a orifice plate flow meter depends on whether it complies with the relevant **standards**, and the multi-parameter calculation aspect is also quite important
Orifice plates have high requirements regarding the installation direction of pressure taps, and attention must also be paid to factors such as material insulation, clogging, and condensation in terms of their suitability for use. Of course, there is also the applicable range for material viscosity.
