Circuit using optical sensor, low power counting electronics, oneclip digital-to-analog converter and operational amplifier converts mechanical readout of water, gas, fuel-oil or power meter to analog signal suitable for online processings.
Difference in oil flow volume through two mechanical flowmeters is converted to analog signal by simple inexpensive circuit. Circuit can be implemented with only minor changes to conventional oil flowmeters and used to measure fuel consumed by oil fired furnace or water heater.
