Electricity Meter Pulse Sensor

The sensor can be easily stuck on to the front surface of any utility meter with an led pulse output.

Electricity meter pulse sensor.

Benefits of using the led pulse sensor. Sensor has the advantage of a built in op amp to ensure good voltage swing and allow direct. The led pulse sensor picks up the light output pulses from a single phase or 3 phase energy meter and converts this into an electrical pulse. The pulse output may be a flashing led or a switching relay usually solid state or both.

Monitoring gas meters without pulsed output or magnet. Tls257 detects light in the visible range. Highly affected by ambient light. By counting these pulses and measuring the time between each pulse the meters kwh value can be calculated.

For single phase domestic electricity meters eg. Connected directly to an arduino digital input with a 10k pull down resistor was able to detect a light pulse from reporter 5193b meter. The rate of this flashing is proportional to the amount of power passing through the meter and so useful information is there to be collected. The optical pulse sensor works by sensing a utility meter s pulsed led output.

The electric pulse can then be used in a suitable logger to monitor energy usage. The amount of energy each pulse corresponds to depends on the meter. Emonth gas with phototransistor or reed switch. British gas smart meters part 1.

Gas meters water flow meters etc the pulse output may be a flashing led or a switching relay usually solid state or both. Single phase and three phase electrical energy meters gas meters water meters. Each pulse corresponds to a certain amount of energy passing through the meter. The led pulse sensor is designed to work with the meter logger 100.

It allows power consumption to be monitored and an alert to be issued in the case of anomaly. Locate the little led on your meeter and mount the light sensor over it to register the power consumption rate blinks. An optical pulse sensor detects the led ir pulse output from a utility meters. Hall effect sensors reed switch debouncing.

The frequency of pulses indicates the power demand. If you have had an electricity meter installed in the last few years or you have installed a solar pv installation your electricity meter s will be electronic with an led which flashes. A tls257 light to voltage converter. Gas meter monitoring with hall effect sensor reed switch.

Need to good ambient light shielding around sensor. Many meters have pulse outputs examples include. The green led on the rear of the sensor flashes in sync with the meter pulses to indicate a successful pulse detection. Set the pulse factor in the example sketch to pulses kwh rating on your meter.

There are a few parameters that need to be tuned for each power meter s pulses kwh usually says xxx imp kwh somewhere on your meter. Each pulse corresponds to a certain amount of. In the case of an electricity meter a pulse output corresponds to a defined amount of energy passing through the meter kwh. A simple autonomous solution for remote electricity meter reading yellow pulse transforms a conventional electric meter with an s0 output or dry contact into a communicating meter.
