Electromagnetic flow meters

Electromagnetic flow meters for accurate conductive liquids measurement

WIKA electromagnetic flow meters provide precise measurements of conductive liquids offering many important advantages compared to other technologies, such as exceptional long-term stability, maximum process reliability, no pressure drop and zero maintenance. WIKA electromagnetic sensors are available in different versions in terms of body and lining materials, pipe connections and applications (from economical solution for irrigation up to highly accurate custody transfer as per MID MI-001, OIML R49). They can be coupled to WIKA digital signal converters, supplied in compact and separated configurations, able to deliver accurate flow measurement and manage communication with the external control systems, even in absence of power supply. With no moving or intrusive parts these WIKA instruments ensure fast response time and ease of installation.

How do electromagnetic flow meters work?

Electromagnetic flow meters are used to precisely measure conductive liquids. The measuring principle is based on Faraday's law of induction. According to this law, a conductive liquid can be measured by its voltage as it passes through a magnetic field. The advantage of electromagnetic flow meters is that they work even in the absence of power supply and can be used regardless of pressure, temperature, density, viscosity and aggressiveness of the measured substances.

Where are electromagnetic flow meters mainly used?

Electromagnetic flow meters are used wherever media flow, for example in the field of water and wastewater. However, media with solid components, such as sludge and concrete, or aggressive media can also be measured precisely. Areas of application include earthquake devices, fire protection devices, refrigeration technology, civil engineering, mining or in the process industry. WIKA signal converters, e.g. type FLC-608, are attached to electromagnetic flow meters in separate or compact configuration. This generates, for example, current for the solenoid coil and manages the communication to external control systems
