Level Measurement & Control
Interkama 2005 saw Krohne introducing an addition to the family of its H 250 all-metal VA flowmeters. This device is capable of measuring downward flow direction. This means that the H 250 is now available for all directions of flow, both horizontally and vertically. The H 250 U flowmeter features all the advantages of the H 250 family. The H 250 U is suitable particularly for use in plants where, for example due to the process, the direction of flow is from top to bottom.
The H 250 U flowmeter operates on a modified float measuring principle in which a guided float adjusts so that the flow forces acting on it are in equilibrium with a counteracting elastic force. Like the other devices of the H 250 series, two electrical signal converters in 2-wire technology are also available for the H 250 U. The ESK 2 features an analog current output 4 to 20 mA with HART interface, while the ESK 3 is equipped with Profibus PA interface. The process temperature range is between -70 and +200°C, the ambient temperature range in the standard version is -20 to +90°C.
With M9 indicator, the float position is indicated direct as a flow rate on the scale. The multipole, patented ring magnet is a component part of an effective eddy-current brake. For aggressive atmospheres or special requirements (eg seawater resistance), the housing can be supplied in corrosion-resistant stainless steel. Connections are optionally available as flanged or screw connections.
Precision measurement for ultra-pure water systems
Flow Measurement & Control
[Sponsored] Ultra-pure water (UPW) is essential in industries where even minor contaminants can impact product quality and process integrity. Anton Paar’s L-Cor Coriolis mass flowmeters provide a highly accurate and hygienic solution by directly measuring the mass of the liquid using the Coriolis effect, ensuring a high level of cleanliness.

Editor's Choice Flow Measurement & Control
It is very important that reboiler temperature controls operate well in petrochemical refineries, or the product quality can really suffer. I was asked to check such a control in a refinery where they were having problems with one of these controls.

Editor's Choice Level Measurement & Control
The operators in a petrochemical refinery were having great trouble in trying to stabilise the condensate level in a vessel, and this was adversely affecting other loops downstream. Several unsuccessful attempts had been made to retune the controller.
