For the storage processes of ethanol of a Swedish producer the guided wave radar for continuous level determination was implemented within several tanks. In addition, TDR sensors meet the highest safety standards, which makes them the technology of choice especially in the oil, gas and chemical sectors. With these capabilities, TDR sensors make a noticeable contribution to increasing the productivity of the plant. Robust sensor design that can be used in a variety of ways Radar technology has gained more and more importance over the past decades and has been continuously developed. The area of application now extends from simple installations to complex process vessels with a wide variety of challenges. In addition to free-radiating radar sensors, the radar category also includes those based on guided microwave technology, which are often referred to as TDR (Time Domain Reflectometry) or GWR (Guided Wave Radar). Above all, the versatility and insensitivity to changing process conditions make TDR sensors a popular all-rounder. In the course of modernizing its plants, an ethanol producer in Sweden was looking for a smart…

UWT offers you the right solution for your interface measurement Continuous measurement There are applications not only in the chemical, petrochemical or oil & gas industries but also in other industries, such as Oil & fat separators where a separating layer between two liquids or a liquid and foam is to be measured. The particular challenge for the measurement technology are mainly deposits, adhesions, chemicals and any emulsion layers that may occur. With the NivoCapa® 8000 and NivoGuide® 8000 series, UWT offers two reliable sensor families that meet the most diverse media to be measured, requirements and installation positions. Point Level Measurement The capacitive measuring method is ideally suited to precisely record or measure the transition between two liquids or a liquid and foam. Sensors for interface measurement are designed to have a high sensitivity, a high chemical resistance and a robust design with regard to mechanical stress and deposits or adhesions. With the Capanivo® 7000 and Capanivo® 8000 series and the…

Project planning options for interface detection with NivoBob® or Vibranivo® from UWT There are several industries where sludge levels or solids in liquids need to be measured. For example, in sediment containers or basins, filters or lamella separators in the metal industry, chemical plants, lime or gravel works and the waste water industry. The measuring accuracy and durability of the sensor technology is important. Dirt, chemicals and gases often affect the sensors and require special resistance. The NivoBob® series NB 3300/3400 meet the requirements of many interface measurements and are very reliable due to the simple measuring principle. For level evaluation an analogue signal 4-20mA and a Modbus RTU/Profibus DP interface are available. Vibrating forks of the Vibranivo® series VN 1000 or VN 5000 can be used to measure the level of sludge and solids in liquids. The parts in contact with the medium are made of resistant stainless steel. With the versions VN 1030 and VN 5030 even depths of approx. 4 m when installed from above in a tank or basin.…

Solutions for tricky level measurement challenges What is radar? Radar is the abbreviation for "radio detection and ranging" which means "radio-based location and distance measurement". This technology is based on electromagnetic waves. A radar device emits a concentrated electromagnetic wave, which is reflected by objects as an echo and then evaluated by the device according to various criteria. Depending on the application, the following information can be obtained from the reflected waves: -the angle or the direction to the object -the speed of an object (Doppler effect) -the contours of an object -the distance to the object The latter point means that radar technology is also used for determining fill levels. This has become increasingly important in recent decades and has been continuously developed. The areas of application now extend from simple storage tank applications to complex process containers with a wide variety of challenges.
