Apure PCM610 series Differential pressure transmitter

How to measure the level in a water bottle

How does differential pressure work?

Differential pressure gauge can also be used to measure the flow of liquid in the pipeline. Differential pressure meter by measuring the pressure difference between the before and after the orifice plate to measure the flow. Differential pressure table is a kind of simple and convenient way to obtain process visual indicator.

Why is differential pressure important?

Hvac system is responsible for the increase of pressure. This pressure differential is very important because it helps to prevent cross contamination. Dust particles produced during granulation may enter the air and contaminate other products.

What's the relationship between differential pressure and flow rate?

As the flow increases, more pressure drops occur. Upstream and downstream of pulse pipeline will flow routing to measuring the differential pressure transmitter to determine fluid flow
