E&H FLOW METER PDF

Flow measurement for liquids, gases and steam Product overview for applications in liquids, gases and steam Consistent product quality, safety, process optimization and environmental protection — these are only a few reasons why industrial flow measurement is becoming more important all the time. Water, natural gas, steam, mineral oil, chemicals are some of the fluids that have to be measured day in, day out. There is no single, across-the-board technology suitable for all these applications, so you can choose the flowmeter best suited to your process needs from our comprehensive product basket. Benefits From the communication-capable single measuring point to the complete solution for higher-level control systems: you can always rely on the fact that we customize our products to your process requirements. Together with automated process control and state-of-the-art communication interfaces fieldbus systems , flow metering has advanced into more and more new fields of application in recent years. You can choose among various measuring principles - electromagnetic measuring of volume flow, mass flow based on either the Coriolis or thermal principle, measuring of volume flow based on the vortex or ultrasonic principle.

Electromagnetic flowmeters Proven flow measuring technology for all electrically conductive liquids in every industry Electromagnetic flowmeters have been used throughout industries for more than 60 years.

These meters are applicable for all conductive liquids, such as water, acids, alkalis, slurries and many others. Typical applications are monitoring of liquids, filling, dosing and precise measurement in custody transfer. Electromagnetic flowmeters Our product finder helps you to search for suitable measuring devices, software or system components via product characteristics.

Applicator leads you through an individual product selection via application parameters. Go to Applicator In the industrial environment, electromagnetic flowmeters are primarily used in water management and in the processing, life sciences and food industries. In tunnel construction and mining, robust magmeters are often the only option for measuring highly abrasive ore slurries with entrained solids, sand-water mixtures, filler materials or bulk solids with the required accuracy.

This dynamo principle also governs the way electromagnetic flowmeters work. As soon as the electrically charged particles of a fluid cross the artificial magnetic field generated by two field coils, an electric voltage is induced.

This voltage, tapped by two measuring electrodes, is directly proportional to the velocity of flow and thus to the flow volume. The magnetic field is generated by a pulsed direct current with alternating polarity.

This ensures a stable zero point and makes the flow measurement insensitive to multiphase or inhomogeneous liquids, as well as low conductivity. Benefits The measuring principle is virtually independent of pressure, density, temperature and viscosity Even fluids with entrained solids can be metered, e.
