Electromagnetic flowmeters JUMO offers electromagnetic flowmeters especially for flow measurements in liquids with an electrical conductivity greater than 5 µS/cm. The devices in the JUMO flowTRANS MAG series were designed for the process industry. They are used in various liquid media with different features (e.g. for viscosity, concentration, and density). Examples of these media include water, drinking water, wastewater, pastes, acids, solvents, sludge, fruit juices, and puree. The measuring principle The Faraday laws of induction provide the basis for the electromagnetic flow...

Calorimetric flow sensors The JUMO PINOS L02 is available for flow measurements in liquids, regardless of whether they are conductive or not. This device functions according to the calorimetric measuring principle so that it does not require any wear-prone mechanical parts. The device is suitable for measuring flow velocities, but can also be used for monitoring pumps, cooling circuits, and heat exchangers. The measuring principle The calorimetric measuring principle is based on the cooling of a heating element from which heat is extracted by the passing medium. A reference sensor is...

Paddlewheel flowmeters A simple flow measurement in liquids can be carried out with the JUMO flowTRANS MAG PW I01 paddlewheel flowmeter. This device consists of a sensor and a paddlewheel. The paddlewheel technology allows flows in a wide variety of liquids to be measured and monitored. The measuring device can be used universally in many applications and is ideally suited for installation in confined spaces. The measuring principle The paddlewheel technology is based on a contactless transfer of the rotary motion into a frequency signal. The flowing liquid sets the paddlewheel in motion....

Flowmeters according to the differential pressure principle Flow measurement according to the differential pressure principle is used especially in gases and steam, but also in all liquids. For this purpose JUMO offers devices from the JUMO flowTRANS DP P and JUMO flowTRANS DP R series, which are based on differential pressure measurement. You can measure the flow using either a pitot tube or orifice plate. The generated differential pressure is acquired with the JUMO dTRANS p02 or JUMO dTRANS p20 DELTA differential pressure transmitter and converted into a proportional flow signal. The...
