Frequently Asked Questions

  • What type of fluids can the LF502 measure?

Volumetric flow rate of electromagnetic fluids is what LF502 is designed to measure

  • Are Flowmeters for Both Horizontal and Vertical Installations?

LF502 is capable of being fitted and hanged both horizontally and vertically.

  • Is it Safe to Use The Flowmeter In An Explosive Environment?

No, use of the LF502 in an explosive atmosphere poses a safety hazard and should not be used.

  • What is the Minimum Ohm requirement for The LF502 to Work?

To guarantee stable performance, the LF502 must be connected to a ground with resistance of 100 ohms or less.

  • Is There An Display Device For LF502?

Yes, there is optional 2*16 character LCD which is backlit, for setting parameters and showing measurements.

  • What Must Be Kept In Mind During The Installation Process Of The LF502?

Do not installation during wet conditions and humidity and avoid touching piping and wiring during the electric shock.

  • What Is The LF502 Output Current?

The LF502 signals directly related to the flowrate in 4-20mA DC.

  • Is The LF502 Capable Of Measuring Flow In Partially Filled Pipes?

Yes, the LF502 is specifically intended for providing good flow measurement in partially full pipes.
