TIC-LF502A Introduction The LF502 electromagnetic flowmeter uses Faraday’s Law of electromagnetic induction in the same way as conventional electromagnetic flowmeters to measure the flow rate. Position of electrodes in the LF502 is so designed that it can be used even in a partially-filled pipe to measure the flow rate.
TIC-LF502A 2 Required straight pipe length: 10D minimum on upstream side and 5D minimum on downstream side Note: D is a nominal m eter size. Fluid conductivity: 100µS/cm minimum Fluid temperature: 32 to 131 °F (0 to 55 °C ) Ambient temperature: 14 to 122 °F (-10 to 50 °C ) Dimensions and Weights: See figures 3 to 5.
