Differential pressure transmitters measure the difference of two or more pressures fed as inputs to a sensing unit. They were first put into practice in the 1950s and are still one of the technologies that are frequently used to measure the liquid level in industries. Differential pressure transmitters are used in many industrial applications such as chemical, petrochemical and electric power creation. Amongst the different types of process level measurement equipment, the differential pressure transmitter has seen a massive rise in its worldwide sales volume. The versatility and cost- effectiveness of this device makes it extremely popular.
However, many new level measurement devices have come out over the years and are fast capturing a market share from other older technologies which use mechanical and pressure-based measurements.
A differential pressure transmitter can be used to monitor the hygiene of a filter in a liquid or a gas application. A differential pressure transmitter can also measure the pressure fall across an oil filter. These differential pressure transmitters can also be used to measure the flow or level in pressure vessels.
Some other applications that use differential pressure transmitters include flow measurements, filtration of water for housing as well as commercial works, fuel filtration in diesel engines, chillers, and for medical purposes.
