Abstract

novel handy oil tank liquid level measuring system with optically powered is presented. To realize handy and simple structure, optical powered and micro- consumption detection, the system has taken the PWMIPPM modulation, time division multiplexing (ThM), ratio measurement and pulse width division multiplexing techniques. So, the multiple parameters measurement driven by optical power and transmitted by single optical fiber is also realized. This new transducer has provided with high characteristics: experimental transmitting distance is 500m; total power consumption of the probes is less than 150uw; measurement error: ±0.10( in the measured temperature range of —20-50C) and ±0.04KPa(in the measured pressure range of 0-100Kpa). The measurement accuracy of the liquid level and reserves is mainly determined by the pressure accuracy.
