Understanding Differential Pressure Measurement: Filter Example

- Опубликовано: 28 ноя 2018
- In many applications fluids passing through a pipe require filtering this results in the need for continuous differential pressure monitoring. Differential pressure gauges, switches and transmitters help monitor your processes.
Differential pressure is measured by placing taps both before and after the filter. A differential pressure measuring instrument can be connected to detect the high side and low-side pressures. The instrument will report the difference between the two sides. The saturation point will be indicated when the Delta P value reaches a predetermined threshold. This value was derived from a calculation that factors in the flow rate fluid viscosity and filter characteristics. The filter manufacturer can be contacted for help in identifying the optimum differential pressure value that tells you when it's time to service the filter.
