Automation24: Operating principle of volumetric flow sensors

Volumetric flow sensors belong to the category of Process sensors and are often also referred to as Flow metersMagnetic-inductive volumetric flow meters and Mechatronic volumetric flow sensors can be distinguished. The latter is based on the principle of a spring-supported piston. The piston is located in the valve seat of the housing and is lifted by the flowing medium against the spring resistance. The piston position is detected via an inductive sensor and is output as a binary signal. The magnetic-inductive volumetric flow meters, however, are based on Faraday‘s principle of induction. The conductive medium flowing through a pipe with a magnetic field generates a voltage proportional to the velocity or the flow quantity. The sensor electronics processes the voltage determined via electrodes and provides it as an analogue value for further processes.

Applications of volumetric flow meters are, for example:

  • Volumetric flow monitoring in cooling circuits of induction furnaces and machine tools
  •  Flow rate measurement of conductive media, e.g. in coolants in welding systems

Order volumetric flow meters online from Automation24 – delivered in 24 h.

Automation24 offers you exclusive volumetric flow meters at low prices. We have concentrated the preselection we have for you on the manufacturer ifm electronic who has been proven in the market of flow meters to have higher quality against the competitors.

The offered portfolio includes both magnetic-inductive such as the Magnetic-inductive flow meter ifm electronic SM2000 as well as mechatronic flow meters such as the Mechatronic flow meter ifm electronic SBY323 with very high accuracy, repeatability and measurement dynamics. You will also find compressed air flow meters, such as the ifm electronic SD6000, for example, with which even minute quantities such as leaks can be reliably detected. A pressure rating of 16 and 25 bar can be selected as PNP NO, freely programmable as NC or NO, with analogue or pulse output. The switch points of the mechatronic volumetric flow sensor can be (pre)set continuously. The magnetic inductive flow meter has a 4-digit alphanumeric LED display for representation of the units. We offer a comprehensive choice of Volumetric flow meters – therefore simply use our online feature filter to filter the volumetric flow meter that meets your technical requirements.

At Automation24 you find a large selection of flow sensors at very favourable prices.
