Electricity Meter Pulse Sensor

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.

Electricity meter pulse sensor. By counting these pulses and measuring the time between each pulse the meters kwh value can be calculated. The led pulse sensor is designed to work with the meter logger 100. Each pulse corresponds to a certain amount of. Sensor has the advantage of a built in op amp to ensure good voltage swing and allow direct.

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. The pulse output may be a flashing led or a switching relay usually solid state or both. In the case of an electricity meter a pulse output corresponds to a certain amount of energy passing through the meter kwhr wh. 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.

Single phase and three phase electrical energy meters gas meters water meters. Set the pulse factor in the example sketch to pulses kwh rating on your meter. Tls257 detects light in the visible range. Gas meter monitoring with hall effect sensor reed switch.

An optical pulse sensor detects the led ir pulse output from a utility meters. The sensor can be easily stuck on to the front surface of any utility meter with an led pulse output. The optical pulse sensor works by sensing a utility meter s pulsed led output. Many meters have pulse outputs examples include.

It allows power consumption to be monitored and an alert to be issued in the case of anomaly. Emonth gas with phototransistor or reed switch. Direct monitoring of power meter pulse using raspberry pi an ldr. Benefits of using the led pulse sensor.

The electric pulse can then be used in a suitable logger to monitor energy usage. Gas meters water flow meters etc the pulse output may be a flashing led or a switching relay usually solid state or both. Locate the little led on your meeter and mount the light sensor over it to register the power consumption rate blinks. British gas smart meters part 1.

Connected directly to an arduino digital input with a 10k pull down resistor was able to detect a light pulse from reporter 5193b meter. 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. List of common uk gas meters. Monitoring gas meters without pulsed output or magnet.

Highly affected by ambient light. Need to good ambient light shielding around sensor. The amount of energy each pulse corresponds to depends on the meter. In the case of an electricity meter a pulse output corresponds to a defined amount of energy passing through the meter kwh.

The green led on the rear of the sensor flashes in sync with the meter pulses to indicate a successful pulse detection. 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. Each pulse corresponds to a certain amount of energy passing through the meter. For single phase domestic electricity meters eg.
