General Specificaition

Position of electrodes in The LF502 Electromagnetic Flowmeter is so designed that it can be used even in a partially-filled pipe to measure the flow rate.

Improved functional magnetic field distribution technique enables a high-precision flow measurement continually from low-level to fully-filled flow conditions. This eliminates unnecessary piping work such as lifting the downstream pipe section to fill the detector pipe.

Compared with flowmeters measuring the flow rate by means of flow level, the obstructionless LF502 flow-meter does not usually allow mud, sands and other solid sediment stay at the bottom of the detector pipe and is unaffected by wave or floating solids on the fluid surface.

The AF900 Hand-held terminal (HART(*1)Communicator) can be used for remote control.

  • *1 HART protocol (Highway Addressable Remote Transducer) is a communication protocol for industrial sensors recommended by the HCF (HART Communication Foundation).
