Event Duration Measurement (EDM) in Combined Sewer Overflow (CSO) applications has, rightly, become a significant focus for our water operators.Read more
Level Control and Measurement
Fluid Level Control
Fluid level control is a mechanism, device or system which monitors, compares and regulates the level of liquids or gases within a process to a set value. Level control is used to adjust the level value to a safe level using electric or pneumatic signals. To provide good control, accurate measurement is paramount.
Fluid Level Measurement
Level measurement determines the position of the level relative to the top of bottom of the process fluid storage tank or silo. Level control and measurement is essential to assure the safety and profitability of industrial processes. This Technology Zone offers an insight into the latest innovations in level control and measurement of fluids.

After the hydrates are removed from natural gas, the next step in processing is natural gas liquid, or NGL, recovery.Read more
AURORA, IL – Power generating facilities have large, open atmosphere collection basins known as sumps that are usually found in wastewater treatment areas. Often constructed of concrete, with depths ranging from four to ten feet, sumps function as collection and treatment sites for waste liquids ranging from storm water runoff to excess make-up water.Read more
KLINGENBERG – Transistor instead of reed: As the first instrument of its kind, WIKA has launched a float switch with a PNP/NPN output signal. The model GLS-1000 detects the level of liquids with an accuracy of ≤ 1 mm.Read more
AURORA, IL – In refineries, gravitational separators known as “boots” are commonly found among, but not limited to, alkylation units, hydrotreaters, cokers and amine units. Extending off of the bottom of these horizontal vessels is a boot where interface can occur between the process hydrocarbons and heavier density liquids, such as residual water, HF acid, glycol or amine.
AURORA, IL – Gas turbines are used throughout power generation plants to drive electrical generators. The compressor of a gas turbine ingests a large amount of air containing particulate matter, aerosols of hydrocarbons and other organic compounds and gases. Although the larger particulate matter is filtered out, the other compounds are deposited on the compressor blades. Compressor washing removes this deposited fouling and restores the aerodynamic profile and compressor efficiency.Read more
