Pressure Measurement For Liquids

There are several principles for measuring pressure in Liquids:

 

PROCESS PRESSURE

Function

In pipelines or closed vessels, pressure transmitters measure the pressure of liquids, gases and vapors. The pressure of the measured medium acts on a pressure measuring cell, which converts it into an electronic signal. These process pressure transmitters are ideal for detecting relative or absolute pressure in applications with condensation or rapid temperature changes.

 

DIFFERENTIAL PRESSURE

Function

In differential pressure measurement, different pressures act on the two sides of an oil-filled differential pressure measuring cell. This converts the pressure differential into an electronic signal. Differential pressure measurement is used to measure pressure, level, density and flow of liquids, suspensions, gases and vapours.

ELECTRONIC DIFFERENTIAL PRESSURE

Function

In electronic differential pressure measurement, two sensors from the VEGABAR series are combined to form a unit. Electronic differential pressure is used for differential pressure measurement in filters and pumps, level measurements in pressure-superposed tanks, as well as for flow, density and interface measurements.
