In the 1950s, temperature-equalizing columns were commonly used in steam drum differential pressure–based devices for measuring water level. However, these columns are problematic because a portion of ...

A pressure transmitter can be used to establish the liquid level in a river, tank, well, or other body of liquid. The pressure at the bottom of a liquid filled container is directly connected to the ...

There are essentially four different types of pressure measurement transmitters. Absolute pressure transmitters measure against a vacuum, meaning that if no pressure is applied, the reading would ...

In most applications, level measurements need to be quantified and sent electronically to an automation system, which requires some type of instrument. Sorting through the instrument selection process ...
