Capacitance type Electromagnetic Flowmeter
LF511/LF541/LF516/LF546

Electromagnetic flowmeter separate type converter LQ500 image Certification No. Z01207 image. FM(C US) APPROVED image. 3A FDA Approved (Sanitary type Only) image.

General Specificaition

The capacitance type Electromagnetic flowmeter, model LF511/LF541, employs the surface electrode system outside the alumina ceramic tube, therefore, the electrodes do not come in contact with the process fluid. Its unique technology and mechanical design make it available for use not only on conventional applications but also on new applications such as low conductivity, abrasive and high concentration slurry.
Furthermore, this meter gives a stable flow measurement even though the insulation solid adheres to the wall of the tube.

The LF511 detector can mount with the LF541 converter as combined type.

The alumina ceramic tube for LF511 detector is highly resistant to extreme temperatures and negative pressure.The multi-functional LF541 converter has an unique Noise-suppression Circuit & Advanced Algorithms, therefore, this flowmeter is highly resistant to noise and provides a stable output even for fluids containing slurries.

The AF900 Hand-held terminal (HART*1Communicator) can be used to communicate with the flowmeter from remote places.

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