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 ...

The need for accurate and reliable level measurement systems is increased by the demands of advanced automated processing systems, more stringent process control and strict regulatory requirements. By ...

Drive process engineers require more reliable and precise level measurement systems because of the needs of sophisticated automated processing systems, an increasingly stringent regulatory environment ...

More than one level of measurement technology has proven viable for the range of applications found in coal-fired power plants. Because different coal-handling processes exist within a single power ...

Submerged hydrostatic level measurement in liquids storage tanks is a viable replacement for guided-wave radar (GWR) in the same application and can be installed without interrupting operations. This ...

AutomationDirect has added more ProSense and AchieVe submersible level transmitters to their lineup. The ProSense GLPT series of general-purpose submersible level sensors are designed for water ...

The right level instrumentation is key to keeping boilers on an even keel. Guided-wave radar offers a critical combination of capabilities. If asked to make a short list of factors able to improve ...

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 ...

OVER THE YEARS, several different level-measurement technologies have proven viable solutions for a broad range of industrial and municipal wastewater applications. However, because of the many ...

All the components are easily obtained or manufactured. Any non-magnetic metal can be used for the probe. In this case, stainless steel was used. TDR Detailed Implementation To make a TDR measurement, ...

What’s the difference between a transmitter and a sensor? Nine different types of sensor transmitters. How does each type of transmitter work? What are the components of each transmitter type? Sensors ...

There are many types of sensing used to measure liquid levels.For example: Using a float to drive a resistive element Using capacitive measurement Using ultrasonic measurement This series of three ...
