ptf600 differential pressure flow meter

The most popular flow metres are differential pressure flow meter sensors. The significant number of appearances reflects the extensive quantity of experience (the measuring technique has been around for 100 years). The volume flow of gases, liquids, and steam are measured with a differential pressure flow metre. They’re beneficial in conditions involving high pressure, high temperature, or large diameter. Chemical, oil, gas, and power sectors are the most common places to find them.
Clean media, such as solvents, chemicals, cooling water, oil, gas, steam, and compressed air, can be measured with differential meters. Backflow preventers, pipelines, heat exchangers, and other related equipment are common commercial and industrial applications.

When Should A Differential Pressure Flow Sensor Be Used?
In general, you choose a differential pressure flow metre because the measuring principle is standardised in ISO 5167, ensuring that the measurement results are accurate.

Differential pressure flow meters have the following advantages:

Conceptually, it’s a fairly straightforward one.
They can be built out of various materials and used in a variety of gases and liquids.
Temperatures range from -270°C to +500°C, making them suitable for both cold and hot environments.
Because they can be welded, there are fewer potential leak sites.
Measuring element made to measure for the application
It can be employed in huge pipes (up to a few metres in diameter)
Construction is straightforward and durable.
Installation and removal are simple.
Inexpensive.
They can handle a variety of flow rates and pipe sizes.
They have the ability to configure in a bidirectional flow.
It can be used to measure both liquid and gas flow rates.
Because it has no moving parts, this gadget is maintenance–free (or very low maintenance).
It is offered in a variety of sizes.
